ViewSonic Pro8 Series – A great introduction to the installation class


The new ViewSonic Pro 8 Series offers an attractive entry into the installation class from Viewsonic. Thanks to their 5200 lumens of light output, all three projectors offer high brightness for installation in larger meeting rooms, classrooms or smaller conference rooms.


The new Pro8 models

The new ViewSonic Pro8 series is divided into three different models, which differ primarily in their resolution. These are the following:

ViewSonic Pro8520WL (WXGA resolution – 1280 x 800 pixels)

ViewSonic Pro8530HDL (Full HD resolution – 1920 x 1080 pixels)

ViewSonic Pro8800WUL (WUXGA resolution – 1920 x 1200 pixels)


The projectors, or rather the chassis, look identical except for a plaque with the abbreviation of the units resolution at the front.

With the three different resolution classes, the ViewSonic Pro8 series projectors cover today’s resolutions and offer the best prerequisites for different content types and budgets.


High flexibility

The Pro8 series offers flexible optics and vertical lens shift.

The lenses provide a 1.6x Zoom, which provides a flexible installation in terms of distance or image size. This makes them attractive both for smaller and larger rooms. Since the lens values are coupled to the resolution, they look as follows for the three projectors:

ViewSonic Pro8520WL (Projection Ratio: 1.12-1.8)

ViewSonic Pro8530HDL (projection ratio: 1.07-1.71)

ViewSonic Pro8800WUL (Projection Ratio: 1.07-1.71)


The vertical lens shift allows for manual adjustment of the image on the screen. This is an advantage, especially in the case of slightly higher ceilings, since you can better align the picture this way without losing quality.

If the optical alignment via lens shift is not enough, the Pro8 series projectors offer vertical and horizontal keystone correction. Thanks to the 4-corner correction, the image can be digitally fine-tuned and precisely matched to the screen.

Another noteworthy factor is the central lens position. Thanks to this, the projector can be installed in a more visually appealing way. In addition, the installation is easier when the optics are aligned with the screen.



PortAll compartment

A new feature that ViewSonic introduces with the Pro 8 Series, is the Port All Slot . It is located under the casing of the projector and offers enough space for some practical solutions that have also been introduced to the ViewSonic portfolio. The PortAll range offers a MHL-capable HDMI interface, via which various adapters can be supplied with power. In addition, there is a micro USB cable, via which power can be supplied. This is particularly interesting for solutions that are not MHL-capable.

Among the options that can be used in PortAll range include the optional WPG Adapter (Wireless Presentation Gateway dongles) or the new optional ViewSonic HDBaseT dongle. This HDBaseT dongle is so small that it is significantly easier to install than other solutions on the market.



Sonic Expert Sound

The Sonic Expert Sound technology, introduced in recent years by ViewSonic, is also used in the new Pro8 series projectors. All three projectors (Pro8520WL, Pro8530HDL and Pro8800WUL) offer a 2 x 10 Watt stereo loudspeaker. This means a meeting room or classroom will not require any additional speakers saving on purchase costs and their installation.



Supercolor technology

The Super Color technology used by ViewSonic is also used in the Pro8 series. It ensures the most realistic possible color reproduction for DLP projectors. These work with a RGBCYW color wheel. Compared to other devices with such a color wheel division, the colors of the Super Color technology are even more effective.


Network management

As is the case with most installation projectors, the ViewSonic Pro8 series devices offer hands-on network management capabilities. Thanks to the Crestron RoomView Express support, the system allows you to control and monitor up to 250 projectors from a single computer. Even if such a large number of devices are rarely used in one place, you will get an insight into the possibilities that are available to you.



The ViewSonic Pro8 series interfaces are very versatile. A particular highlight is that they offer a total of four HDMI interfaces. Three of them are on the back, the fourth HDMI input is in the PortAll area. Besides the HDMI interfaces, the selection of the other connections is also large. This includes two VGA inputs, one VGA output, one RCA video input and one S-video input. A LAN, a RS232 interface, an IR and a 12V trigger output are available for controlling the projector screen. There are also audio outputs on 3.5 mm jack base as well as audio inputs on stereo RCA and 3.5 mm jack base. Add to this a 3D Vesa connection and a 5V DC USB interface. As you can see, a great variety.



Technical Specs

The basic values, except for the resolution, are the same:

ViewSonic Pro8520WL: WXGA resolution / 5200 lumens / 5000: 1 contrast

ViewSonic Pro8530HDL: Full HD resolution / 5200 lumens / 5000: 1 contrast

ViewSonic Pro8800WUL: WUXGA resolution / 5200 lumens / 5000: 1 contrast



The new ViewSonic Pro8 series not only makes a good impression at first sight, but also our live test convinced us of their quality. Thanks to their chassis size, they can be installed unobtrusively on the ceiling and are still suitable for placement on the table. With the cable cover for the back of the unit, they are even more appealing! The selection of the resolutions is up-to-date and offers a suitable solution as required or budgeted.
All in all, the new projectors of the Pro8 series make a good impression and offer space for a range of exciting accessories.

Acer K650i – Acer launches first LED Full HD projector


Acer K650i – Acer launches first LED Full HD projector

Acer introduces their first Full HD LED Projector, the Acer K650i. Thus, Acer closes its gap between the LED projectors and those with a conventional lamp.

LED technology

Up to now the Taiwanese manufacturer has only offered LED projectors that were equipped with a WXGA DLP chip. Now with the K650i Acer joins other manufacturers like LG, with an LED projector with Full HD resolution. The LED technology offers the advantage of a long-lasting light source. The Acer K650i has a lifetime of up to 30,000 hours in Eco mode so a change of the lamp is no longer a concern and the purchase costs for a replacement lamp are also omitted. Thus, the K650i provides an attractive money saving option.

A further advantage of the LED light source: Compared to the colour wheel technology, it covers a much larger colour space. This provides the projector with a larger colour palette with which it can also display the sRGB color space.

In addition to the colours, the LED technology also influences the contrast and with a value of 100,000: 1, the K650i is very attractive. Its representation of dark images are boosted thanks to the very high contrast ratio.

Hidden Port

This is the first LED projector in the Acer portfolio with the so-called Hidden Port. This is hidden on the bottom of the projector, not as usual under the top cover. The Hidden Port offers enough space to accommodate the optionally available Acer MWA3 Wireless Adapter or the receiver of the optional MWiHD1 Wireless Kit. Thus, the Acer K650i is particularly suitable when you are looking for a smart wireless solution.

Attractive design

As we are accustomed to from the Acer LED projectors, the design of the K650i is very appealing. At first glance, it strongly reminds the Acer K138ST, and we think it has a very elegant finish.


Multimedia Reader

The K650i has a multimedia reader, which can be supplied with data via an SD card or the internal 4GB memory. Supported file types include images, videos, music, office files, and PDFs, this makes the Acer K650i cheap for digital signage use.

Audio features

The Acer K650i is very well equipped in the audio department, offering a 2 x 5 Watt stereo loudspeaker, which provides a decent performance for a smaller room and means that if you want to use the Acer projector for occasional home cinema or gaming sessions, an external loudspeaker is not essential. If, on the other hand, you want to improve on the quality you can link it to a Bluetooth loudspeaker (eg a sound bar) thanks to the Bluetooth audio interface. It also offers the more traditional 3.5mm audio in and out ports too for easy connection to other devices.


The Acer K650i offers two MHL-capable HDMI inputs. One is in the Hidden Port, the other in the back. In addition to the wireless adapter solutions, MHL-enabled smartphones and tablets can also be connected via MHL cables. This allows the transfer of high-definition content directly from the mobile device.

The K650i also has a 5V DC USB connection, so when you use wireless solution like the google Chromecast dongle or an Amazon Fire TV stick, the USB port provides power.

Connection diversity

When looking at the interfaces, the Acer K650i can be compared with its smaller WXGA brother. However, you will discover small but subtle differences: it offers a USB connection as well as the two MHL-capable HDMI inputs. The 5V DC USB port is located on the back and is used for power supply. For the media player the mentioned SD slot is available.

Another change is the direct power connection, many other LED projectors use an external power supply, the K650i does without it and has an internal power supply which is particularly attractive when ceiling mounting.


With the Acer K650i the Taiwanese manufacturer has produced an attractive LED Full HD projector. With its light intensity of 1400 lumens you can easily use it for a range of different application’s. We are convinced however, that it will find its main application area in the home cinema, as the optimum prerequisites for light output prevail in this area. Thanks to its sRGB & Rec 709 support in conjunction with the color-responsive LED image quality, it provides perfect conditions for a successful home cinema image!

What do you think about the new LED Full HD Projector from Acer?

Acer V9800: Acer announces 4K projector!

acer-v9800Now’s the time! Acer announces its first 4K projector! The news was recently announced at their headquarters in Taipei.

4K UHD resolution – Acer V9800

The Acer V9800 has a resolution of 3840 x 2160 pixels to work with 4K Ultra High Definition. Its the first 4K projector within the ranks of the Acer. Thanks to its attractive pricing, the manufacturer hope many home cinema fans will be interested in the V9800. Where exactly the Acer will be priced is not yet known, but it is expected to be in a more attractive segment than the devices previously available with SXRD technology.

4K quality

With a 4K DMD chip from Texas Instruments at the core of the device, the V9800 provides a super resolution video processor to upscale the material on the 4K image. This also means content can be shown in 4K that is currently only available in 1080p quality.

Rec 709

Another interesting feature of Acer V9800 is to support the Rec 709 colour standard. This is used in HDTV content in order to provide optimum colour quality. It also covers the sRGB colour space. This would suggest that it is moving close to the V7500 in terms of colour quality, which impressed us during tests. Thanks to Acer Colour Purity Technology, a RGBRGB colour wheel and a custom lamp control, the V9800 a great foundation with which to work.  Another advantage of RGBRGB colour wheel is the strong reduction of the rainbow effect, it may well be that the rainbow effect is no longer visible.

acer_v9800_b24_blog_2Fan noise

Another positive we have learnt is that the Acer V9800 is listed to run with only 20dB fan noise. This is really a very low figure, so we hope its too low for the viewer to hear at all! Compared to the other home cinema projectors in Acer’s portfolio, the V9800 is likely to be somewhat larger, which goes hand in hand with lower fan noise. We expect it to fall in line with some of the other 4K home cinema projectors on the market. The big chassis lends itself to features such as lens shift.


Although there is not too much information about the first Acer 4K projector at present, the information that is there has made us listen up. The first step toward mass appeal 4K resolution projectors seems to have been made and now it remains to be seen where the Acer will settle on price. The information relating to the image enhancement means we can definitely hope for a good image quality. The V9800 has now shown for the first time live in Taipei and we are eager to know when it will find its way to us, once it does arrive, we will review the Acer V9800 and let you know our thoughts!

Gaming projectors

Gaming Projectors

Looking for the perfect gaming projector? After the world’s biggest video games fair ‘Gamescom‘ learn from us what to look for in a gaming projector. Let’s be honest, gaming on a 2-metre wide screen is much better than on a 24-inch monitor!

What you should look at a projector gaming?

Similar to monitors, there are certain qualities you need to look for in a projector. If you are using a monitor, the response time is an important criteria to look for. With projectors there are other features of importance, the most important of which we have detailed below.


An important point to keep in mind when choosing your gaming projector is the resolution. For current PC games, as well as consoles, the full HD 1920 x 1080 resolution is generally sufficient. You could also consider the WUXGA (1920 x 1200) resolution as well because the Full HD resolution fits within it. For newer consoles like the Xbox One S, offering 4K and HDR support, you can of course look at a 4K projector from the high-end segment, however as you would expect the prices are unnoticeably higher.

Light output

When choosing how many lumens to go for, it is important to know where you want to use the projector. Can the room be darkened or is it slightly lighter, such as in a living room? We would suggest looking at above 2000 lumens if you have control over the lighting and 3000 lumens or more when you don’t.


The most crucial thing here will be ensuring you have at least one HDMI port. This is the standard connection for transferring high definition content from your gaming device to the projector. In addition to HDMI, a DisplayPort connection can be interesting for PC users however this is not yet widespread in projectors.


In terms of features projectors now offer a variety of different properties, which are interesting for gamers and home theatre enthusiasts. Key features include Frame interpolation, MHL-ability and short-throw lenses. More details below!

Frame Interpolation

For gamers, this feature is a must-have. Especially with rapid image sequences as in the projection of car racing or action games, the frame interpolation is very attractive. In general, high end home theatre projectors are equipped with this feature.

MHL capability

Another feature is the MHL capability. An MHL enabled HDMI connection is especially interesting for mobile gamers, because it will allow an MHL -enabled smartphone or tablet to directly connect to them. In addition you can also use MHL wireless adapter.

Short throw Lens

The short-throw lens is a special feature that is especially interesting for movement based games. Where a normal projector needs a greater distance, here a significantly lower throw distance is required. A short throw projector can achieve an image width of 2 m at a distance of approximately 30 to 150cm (depending on the model). Thanks to the short distance you have enough space to move behind the projector without casting a shadow. A short-throw projector can also be particularly useful for smaller rooms where you otherwise would not have the space for a projector.

Gaming projector recommendations

There are several projectors that make great options for gamers. Here are two models that are particularly well suited!


Acer Predator Z650

The Acer Predator Z650 is actually THE gaming projector, since it has the closest links to the gaming scene. The Acer Predator series is known for its PCs and monitors. The range has been extended to projectors with the Z650 and it offers the typical, unmistakable Acer Predator style.

The Acer Z650 is a Full HD 3D projector with short-throw lens. It reaches an image width of 2 m at a distance of 1.5 m. The Z650 offers several features that speak for its suitability for gaming. This includes its RGBRGB color wheel that produces a true-color image display. Its gaming modes are optimized for fast image display and in addition it has an appealing speaker system including DTS sound support. Gamers with an nVidia system will find the Z650 also supports NVidia 3D TV Play.

The Acer Predator Z650 is attractive proposition for any gamer and is a must for fans of the Acer Predator series.


Epson EB-U04

The Epson EB-U04 is a popular multimedia projector, which is a great choice for gaming. Using 3LCD technology, it offers a color-neutral representation, similar to a LCD monitor. The resolution it uses is 1920 x 1200 thus covering the full HD resolution. Thanks to its 3000 lumens, it can even be used in the living room to good effect.

In terms of features the Epson EB-U04 is a little below the Acer Predator, however this is reflected in the lower price of the unit. It has two HDMI inputs, one of which is MHL-enabled and thanks to its compact dimensions, it can be easily transported to a friends as well. A feature that goes hand in hand with its portability is the vertical and horizontal keystone correction of +/- 30 degrees meaning it can be set up almost anywhere.

As you can see, the Epson EB-U04 is a great multimedia projector, which can be used for many different applications. Although it is lacking in some features, thanks to its attractive price and excellent image quality, it will be near the top of anyone’s shortlist!

Acer H7550ST – 3D Full HD Short Throw Projector


The new Acer H7550ST is the Taiwanese projector manufacturers first 3D Full HD Short Throw projector. Another first is that the H7550ST has a hidden internal slot for the google Chromecast dongle! More and more projectors are now used wirelessly, but these systems are usually mounted externally on the projector and therefore can easily be lost, stolen or forgotten. With the H7550ST however Acer have taken a different path and the dongle can be hidden away within the Projector. Not only is this more secure it looks nicer too. Built with entertainment in mind, the H7550ST is just as comfortable in a classroom or meeting room environment.

Short Throw Lens

The Acer H7550ST has a short throw lens meaning it can be placed close to the screen without compromising on image size. This offers an advantage in smaller spaces and also means that the image will be nice and bright as the projector can be close to the projection surface. The short-range lens will produce (for example) a 2m image width with a throw distance of only around 150cm. This is perfect for motion sensitive games consoles such as the Xbox Kinect, the Playstation Move or Nintendo Wii as you have enough space in the room to move behind the projector without casting a shadow on the projected image.

Home Theatre Features

Designed especially for home theatre use, it is crucial that the H7550ST offers 3D as well as a Full HD resolution. This means that 3D Blu-rays can be enjoyed in all their glory and all you will need is a 3D blu ray player and the appropriate DLP link 3D shutter glasses which Acer offers as an optional accessory. If you have a large Blu-ray collection with many 2D movies, you may wish to use the integrated 2D to 3D converter meaning you can enjoy a lot more content in full 3D. Acer have also given consideration to the PC gamer as the projector carries nVidia 3D TV Play ready certification.


Since a projector can often be used in a stand-alone set up Acer has fitted it with 20 watt stereo speakers that are DTS certified making it easy to set up for an impromptu movie or gaming session. It also means you can easily take it to a friends house without having to wire up a complex speaker system.


Internal HDMI Port for the Chromecast Dongle

The H7550ST offers a wide range of connections in addition to the internal HDMI port. These include VGA, component, composite and S-Video along with two additional HDMI inputs, one of which is MHL enabled. A 5V USB port is also available at the back.


As you can see, the Acer H7550ST offers much more than you would think at first glance. It remains to be seen at what price the H7550ST will be available but it is assumed that it will be in line with the Acer H7550BD which offers the same specs without the Short Throw lens. We look forward to both units being available on our website!

Acer H7550ST


Epson home cinema update



The Epson EH­TW5100 is a compact Full HD 3D projector in a appealing white housing reminiscent of the black TW5200. The TW5100 offers a light output of 1800 lumens and a contrast ratio of 13,000:1. Where connections are concerned the TW5100 is very well positioned for a projector in this class as it offers two HDMI inputs, one of which is MHL enabled.

Thanks to its 3D technology, it is suitable not only for home theatre use, but also for gamers. There are a wide range of games on the Playstation and Xbox that can be played in 3D. Like the rest of the Epson range, the projector also offers both vertical and horizontal keystone correction of +/­ 30 degrees making positioning the projector very easy. If sound is required, the projector also offers 2 x 1W stereo speakers you can fall back on if some better speakers are not available.

The Epson EH­TW570 offers an HD ready resolution of 1280 x 800 (WXGA) whilst also supporting the direct 3D capability. Its chassis is black as is the norm for the HD ready home cinema projectors from Epson. Its a more powerful projector than the TW5100 we mentioned above offering 3000 lumens and a contrast of 15,000:1. So not only does it provide a good brightness but a reasonable black level too.

The Epson EH­TW570 does only offer one HDMI port but it does offer MHL capability meaning tablets and smartphones can be connected directly via cable. As above it offers horizontal and vertical keystone correction of +/­ 30 degrees and the internal speaker is a 2W mono.

The TW570 also supports the optional wireless capability like projectors in the Epson business range, meaning that content from iOS or Android devices using the Epson iProjection app can be projected.

Both units offer a gaming mode meaning they are perfect for online gaming, ensuring there is no lag time on the display. They also both work with the Epson ELPGS03 3D shutter glasses.

ViewSonic advanced Connect technology


The ViewSonic advanced Connect technology offers a variety of connectivity for the current ViewSonic projector range. The current projectors that can use the Advanced Connect technology are as follows:


ViewSonic PJD6345

ViewSonic PJD6544w

ViewSonic PJD7533w

Viewsonic PJD8633ws


We will now look into the Advanced connect Technology here in both wireless and wired options.

ViewSonic Advanced Connect mobile

ViewSonic Advanced Connect mobile

For a wireless set up the optional USB wireless dongle (WPD-100) is required. This is plugged into the back of the projector in the USB port. Wireless transmission allows the user to display content from their notebook, tablet or smartphone. For tablets and smartphones an app is available for both iOS and Android devices and can be easily downloaded from the App Store or Google Play. Software is also required for Windows and Mac computers, this software can be downloaded from the ViewSonic website in the download area.

The smart phone and tablet app is capable of handling various formats, such as Office files (Word, Excel, and PowerPoint), PDF’s as well as Pages, Numbers and Keynote files for Mac users. (You will need to save the files onto the device, eg via iTunes.) In addition to documents, photos can also be shown. Another very useful feature is that a live feed from the camera on the phone or tablet is also possible, meaning it can be used as a document camera. Access to Dropbox is possible along with internet browsing as long as the the WLAN configuration permits.

A split-screen mode is also available, allowing up to four users to present their content on the ViewSonic projector simultaneously.

In addition to the feed from the smartphone or tablet, the software offers the possibility of projecting the content from a laptop. The required software (EZ Viewer) is available for Windows and Mac.

When using a wireless connection it is worth noting that, for example, moving data such as the live feed camera function, the transmission speed required is high, and if this is not the case it may lead to stuttering. For the best transmission of moving images, it is worth looking at the Viewsonic Wireless Presentation Gateway WPG-370, since the connection is stronger and the receiver can be connected via HDMI to the projector.

ViewSonic Advanced Connect USB LAN

ViewSonic Advanced Connect kabelgebunden

In addition to the wireless connection variant we have already looked at,  a wired solutions is also available. This allows all projectors with ViewSonic Advanced Connect technology to receive image signals not only on the common interfaces such as HDMI or VGA but also via USB and LAN.

In addition to connecting to a PC or notebook, the use of USB storage media is also possible. This means it is possible to present data directly from a USB stick, which is particularly useful for digital signage applications as a larger input source such as a computer does not need to be present, you just plug in the USB stick and you’re set. Its also a convenient feature for those travelling with the projector.  It is worth noting that the viewer functions are not as versatile as when you connect a notebook since the integrated viewer does not have the full capabilities of a PC, but for standard content, it is usually sufficient.

In addition to this, image transfer via a LAN cable or USB cable is possible. For the USB connection to work, the software must be installed onto the computer, but as it is stored in the projectors internal memory it is as convenient as plugging the the projector into your computer to begin installation. The USB transfer is a very practical feature and can be a big help when there is no HDMI or VGA cables available. A mini-USB cable can often be found as they are widely used by mobile phones and other devices. Video transmission over USB is not a problem either, one might assume that using traditional image connections like HDMI and VGA would be your only option, but the USB cable does a very good job here with very minimal loss of quality. The LAN connection is worth using when a longer distances must be bridged, as traditional image cables such as VGA and HDMI will have limitations on their length. The LAN connection in this case also offers the possibility, as mentioned earlier with the wireless connection, to use the split screen mode. This is particularly useful for conferences, as participants will not have to constantly change, and can all present in parallel.


This concludes our look at the Viewsonic Advanced Connect Technology, and we look forward to seeing it introduced into more Viewsonic projectors in the future!

Acer MWA2 MHL wireless dongle

With wireless technology becoming more and more appealing to projector users, it is only logical that more and more optional solutions become available. In this blog we look at the Acer MWA2 MHL wireless adapter. This uses an MHL enabled HDMI connection to allow wireless presentation from computers, phones and tablets!

An MHL enabled port is capable of supplying power to external devices, this advantage that the Acer MWA2 adapter will not require any external power. A standard HDMI port would not supply enough power to operate an external device such as the dongle. This makes the installation of the device very easy, and is especially convenient for those who have an MHL enabled projector already installed on their ceiling as they will not need to install an additional power connection.

The Acer MWA2 MHL wireless adapter provides not only a simple wireless connection, but much more. In addition to the normal WLAN function it supports Miracast and DLNA . Thus, the Acer MWA2 wireless dongle is useful not only for the business use, but for the home as well.

The wireless function can be used by a diverse range of products. Both windows and Apple operating systems are supported, along with both iOS and Android mobile devices in the form of smart phones and tablets. For all these devices appropriate drivers or apps are available. On the App store and Google play you will find the Acer eDisplay app. Within this app you are given the opportunity to display various content including pictures and PDF’s from the device wirelessly to the projector or display. The Acer eDisplay app even has a connection to Dropbox , so you can pull content straight from your online storage.

A further function of the adapter is Miracast. This technology was created as a counterpart to Apple’s Air Play for the Android system. You have the possibility the mirror the screen of the smart phone or tablet meaning that it is not dependent on an app and its limitations.

In addition to these features, the Acer dongle also has DLNA support . It allows the integration into a home network allowing you to share content from a range of devices on your projector.

Acer makes no compromises where security is concerned either with WPA2 support. The MWA2 Dongle supports all the following security standards : WEP 64/128 bit, TKIP, AES, WPA2 .

Thanks to a fast connection, the dongle is not only suitable for basic files like presentations, but can also be used for the transfer of films and other video content. This means the MWA2 will be a popular addition in a large range of possible uses. They extend from presentations in a meeting through to use in the home theatre or living room via DLNA/Miracast from a tablet or smart phone.

All in all, the Acer MWA2 MHL Wireless Adapter is a very useful piece of kit that will work in any MHL-enabled projector, television or display.

celexon launches first range of cables

celexon HDMI-Kabel und celexon VGA-Kabel

Well known in the projector screen market, celexon is expanding its range. So far, the focus has been mainly on screens and mounts for projectors, but now celexon are launching their own HDMI and VGA cables.

The celexon HDMI cables are divided into two ranges, the Economy and Professional Series.

HDMI Cable Economy series are plastic coated and offer 24 carat gold-plated plugs. They can accommodate for transmission with a maximum 4K x 2K resolution and also support the current 3D standards. An ARC (Audio Return Channel) and Ethernet return channel are also provided. The celexon HDMI Economy cable is available in lengths up to 20m, starting at 1.5m.

HDMI Cable Professional Series offer primarily the same transmission standards, such as 3D rendering, a max 4K x 2K resolution, as well as the ARC and Ethernet return channel. However, the cables are equipped with two solid fitted metal plugs which will produce better transmission quality. Another plus point is the improved insulation covering the cable. The celexon Professional HDMI cable is also available in lengths from 1.5m to 20m.

The celexon VGA cables are similarly split into two ranges, Economy and Professional series.

The VGA cable Economy series is completely plastic-coated , has a cast plug in plastic and double shielded with 2 ferrite filters for maximum noise immunity. The celexon Economy VGA cable is available in lengths from 1.5m to 30m.

The Professional series of celexon VGA cables, like the Economy Series are double shielded and have two ferrite filters to offer strong protection against external noise. The big improvement comes with the 24 carat gold plated plugs, along with the full pin assignment of 3 (RGB) +8 (28AWG) which can be very useful for installers. The celexon Professional VGA cable is available in lengths from 1.5m to 40m.

Acer LED series


Acer gives its range of LED projectors a makeover! They have released updates to two of their range whilst adding a third unit to the series.

After the update, the Acer K130 will become the Acer K135 and the K330 will be the Acer K335. The new addition to the range is the Acer K132. At first glance, it is very much like the K130, but in a slimmed down form.

Let’s look at the changes in detail.

The Acer K335 keeps the same resolution as its predecessor and thus offers 1280 x 800 pixels (WXGA resolution). The changes come with the light output and contrast figures. Its light output is now at 1000 lumens, while its predecessor was equipped with only 500 lumens. However, this improvement comes at a price, because the K335 has become larger and therefore heavier. It is fair to assume that this is due to a larger number of LEDs needed to produce the light, and the cooling systems needed to keep them working.

Due to the size increase, the chassis itself has also been changed, but we think this is an improvement on the K330. The other big improvement previously mentioned was the contrast ratio, its predecessor was operating at a level of 4000:1, where as the Acer K335 now offers 10,000:1. We are excited to see how the improved specs of the Acer K335 look in comparison to its predecessor. The connections of K335 look to be exactly the same at first glance (HDMI, VGA, USB Type A, SD card, mini-USB, 3.5mm jack, and a RCA video port).

On closer inspection however, it reveals that the HDMI port now supports MHL standard. This is great news for users of MHL-enabled mobile phones. Like its predecessor, the K335 also features a media reader that is able to play various formats from a USB drive or SD card. These include Word, Excel, PowerPoint, PDF, JPEG, MPEG4, H264, MP3. This makes it one of the most versatile media readers you will find.

The Acer K135 follows the K130. When you compare it to the predecessor there do not look to be as many changes. The WXGA resolution and contrast of 10,000:1 remain the same. Only the light output was improved, from 300 to 500 lumens. The connections also remain the same. The projector has HDMI, USB Type A, Micro SD Card Slot, Universal I / O, and a 3.5mm jack connection. However, as with the K335 the HDMI connector also supports the MHL standard. Similarly to the big brother of the K135, it is also capable of various Office files, PDFs, images and videos from USB stick or the Micro SD card. Thanks to its light weight of just 0.43 kg is the Acer K135 well suited when it comes to mobile use. In addition, it is also assumed that the external power supply is compatible with some Acer notebooks, just as was the case with its predecessor.

Finally, the new LED projector in the range is the Acer K132. At first glance it looks like the K135. However, upon closer inspection, it is found that this is a cut down version. The Acer K132 only has an HDMI input and a universal I / O connection. All the other connections have been omitted and this means there is no USB/SD viewer function. This is reflected by the much lower price of the Acer K132. This makes it ideal for those users who do not need the viewer function, since they play content from their computing device.

All in all, the new LED projectors from Acer are very interesting. The light output and size combination offered by the K335 is a rare find in the market. The road to the complete replacement of the conventional projector lamp is slow, but we think this shows a major step in the right direction. We are excited to see what awaits us in the near future!
