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.
