Viewsonic VP3D1 3D Processor Brings HDMI 1.4a to 3D DLP Projectors

April 4th, 2011 · 25 Comments · General 3D News

It seems that Viewsonic has kind of quietly launched in Europe (still not available in US) a new product that will ensure HDMI 1.4a support for their wide range of 3D DLP projectors – the Viewsonic VP3D1 3D Processor. This device does pretty much the same thing that other similar solutions already available do and that is to convert from HDMI 1.4(a) 3D input to HDMI 1.3 frame sequential stereo 3D that 3D DLP projectors can understand and display. The idea is to be able to connect a device such as the PlayStation 3 console or a Blu-ray 3D player through this adapter to a Viewsonic 3D DLP projector and make them work together. So the Viewsonic VP3D1 3D Processor can pretty much be considered as an alternative to Optoma’s 3D-XL adapter or the VIP 3D-Gamer device, and although Viewsonic does not mention it, it should also be compatible with other brands of 3D DLP projectors. Of course we are talking about models that have an HDMI input and that can take 720p 3D input and display it, so not all 3D DLP projectors will work with this solution.

The device has two HDMI 1.4a inputs that support not only frame packaged, but also Side by Side and Top/Bottom input in 720p or 1080p/i format and can output it via single HDMI 1.3 connector in 720p frame sequential stereo 3D to a compatible projector. The 3D processor does not need any special 3D glasses, so with a pair of normal DLP Link shutter glasses for the projector you should be ready to watch in stereo 3D format, even when using HDMI 1.4a input. You can also use the 3D processor as a pass-through HDMI switch for 2D content if you connect two different devices to it.

VIP 3D-Gamer is an HDMI 1.4 to 3D DLP Projectors Video Converter

January 19th, 2011 · 5 Comments · Other S3D Tech

It seems that the Optoma 3D-XL adapter may have a cheaper alternative that can be available on the market earlier, but with a bit more limited functionality. There is a new company called Video Innovation Products (VIP) that should soon start shipping their VIP 3D-Gamer conversion adapter that can have HDMI 1.4(a) stereo 3D input and output frame sequential stereo 3D that can be understood by 3D DLP projector. This means that you should be able to connect your PlayStation 3 console via this adapter to a 3D DLP projector and play games in stereo 3D mode. The adapter is just converting between the formats, so for the projector you would still be using a pair of traditional DLP Link glasses. The adapter might also be able to turn your 3D DLP projector into a compatible with 3DTV Play for gaming as well, although that needs to be verified if it will work when the converter becomes available in the beginning of February. The price announced for the VIP 3D-Gamer video conversion adapter is $199 USD and you can buy it also bundled with a pair of DLP Link glasses for $259 USD (the glasses do look very much like 3D Vision) or a separate pair of glasses for $79 USD each.

The VIP 3D-Gamer product is designed only for gamers and supports only the 720p 50Hz/60Hz 3D modes as input over HDMI 1.4(a), it is however not compatible with the 1080p 24Hz 3D resolution used for movies. This simply means that you will not be able to use this adapter together with a standalone Blu-ray 3D player to watch on your 3D DLP projector, but the company apparently has another more flexible solution for 3D movie lovers. They should also soon start offering a 3D-Displayer and 3D-Theater products that will offer more features and support both the gaming and movie playing in stereo 3D coming from all kinds of 3D-ready devices using HDMI 1.4(a) and being played back on a big screen supplied by a 3D DLP projector, as well as some other ore advanced features. But these products will probably be more expensive and will probably compete with the Optoma 3D-XL adapter both in terms of features and price and they will most likely be released at the same time too.

But back to the coming very soon VIP 3D-gamer product. Aside from only supporting 720p 50/60Hz 3D input you will also need to have a 3D DLP projector that has and HDMI input and that is with native resolution of 720p (able to output 720p in stereo 3D mode) like for example the Acer H5360 or Optoma HD66. The adapter itself is apparently powered over a mini-USB port, so you will probably need to have a device to plug it in or an USB power adapter, but the USB port might as well be usable for lets say firmware upgrades. You should also have in mind that that Side by Side or Above/Below inputs are not being supported as of this moment as only the HDMI 1.4(a) frame packaging format can be translated into frame sequential stereo 3D. And as will all image processing devices you should be aware of the fact that adding the VIP 3D-Gamer adapter may introduce slight additional lag on top of any possible lag that the projector may already have. Now let us wait a bit more and see what the first people that get the device will report about it…

The Optoma 3D DLP Projector Adapter 3D-XL is Coming in January

October 31st, 2010 · 23 Comments · General 3D News

It seems that Optoma is almost ready to to release the much hyped 3D DLP Projector Adapter 3D-XL that will add support for HDMI 1.4a input for stereo 3D content to 14 of the company’s 3D-capable DLP projectors as well as 3D DLP projectors from other brands. Optoma has officially announced more details about the adapter as well that the 3D-XL projector adapter will be available in January 2011 and although the official price is not yet announced, Amazon has already listed the 3D-XL adapter for pre-order with a price of $499 USD. It certainly won’t come cheap, but in the price there will be one pair of Optoma’s BG-ZD101 3D active shutter glasses sold for $99 USD and based on the DLP Link technology. And if you compare the price of a 3D DLP projector plus the 3D-XL adapter to a 3D HDTV or some of the high-end 3D-capable projectors that were already announced to feature HDMI 1.4(a) S3D support, you might still be saving quite a lot of money.

But why would you need to have HDMI 1.4a compatibility for stereoscopic 3D support, when your 3D DLP projector already can receive 3D data and display it? Well, actually you might not, unless you want to be able to lets say connect your PlayStation 3 console to the projector and play stereo 3D games on it, or connect a 3D-capable set-top-box, or a standalone Blu-ray 3D player. Of course that also includes other 3D-capable devices that support 3D video output over HDMI like the Fujifilm Real 3D W3 camera, Sony’s 3D Sweep Panorama-capable digital cameras and probably a lot other that are yet to come. If you need it or not is something for you to decide, but if you already have a 3D-capable DLP projector this adapter can prove to be a good way to ensure big-screen 3D viewing…

On the front side of the adapter there are just three buttons, one for turning on and off the adapter, one for switching between 2D and 3D mode and one for using one of the two available input ports. By activating the 2D mode you are practically doing a pass through of the signal to the projector and in this mode you can send 1080p data, but in 3D mode you are limited to 720p only. And considering the fact that there are still no 3D DLP projectors with native resolution of over 1080p this is actually not such a big problem, and when the first 1080p 3D-capable ones start hitting the market probably early next year they will most likely also come with built-in HDMI 1.4a support anyway.

You should be aware of the fact that your 3D DLP projector should have an HDMI input in order to work with this adapter as the output is only in the form of an HDMI. You can see that there are two independent inputs, meaning that you can connect two different 3D devices and switch between them without having to change cables. The adapter is designed to be used with DLP Link glasses, so there is no need for an external IR emitter, although the adapter has a 3-PIN mini DIN (VESA Sync) output available.
