Default DisplayPort to DVI MST Hub with PLP support

Quote:
Over the recent years we have seen multi-screen video technologies really improve to achieve some great things such as AMD's Eyefinity and Nvidia's Surround, we even have the Matrox TH2G and Mview products.

Unfortunately, there is still a lack of any DisplayPort to DVI Multi-Stream Transport (MST) hubs on the market and there is even less support for Portrait-Landscape-Portrait (PLP). The only way of achieving PLP for gaming is via the SoftTH software, which from experience is less than user friendly, and also limited to DirectX9.

Here at WSGF, we strive to push technology to its limits and bring to our community the very best in multi-monitor products, knowledgeable support and game fixes. With this in mind, we are interested in bringing to market a device that would allows users to have great flexibility in the way they wish to setup their displays and overcome most of the problems that plague many of our readers.

Recently I got in touch with a device manufacturer about tweaking one of their existing products to cater to our community's needs. The device in mind would be an external unit that sits between the computer and the monitors, much like the Matrox TH2G device; however the device we would like to offer to the community would contain the following specs...

Input: 1x DisplayPort v1.2 full size connector
Output: 3x or 4x Dual-Link DVI
If you would be interested in this device, please join the site (if you haven't already) and share your thoughts with us.

Support for each monitor output to have its own configuration:

Bezel Correction - Allows for each monitor to have independent bezel correction.
Projector Edge Blending - Blend the edge of projectors to get that perfect alignment.
Rotation - Independently support different rotations per monitor, great for PLP setups!
Cropping - Create elaborate non-rectangular monitor configurations.
Image UP/Down Scaling - Take a portion of your input signal and scale it to fit your monitors as needed.
Refresh Rate Conversion - Each monitor can be provided with a refresh rate that is optimum for it, example (60/75/60)
DirectX Independent - Totally independent of DirectX version giving both forward and backwards compatibility!
Different Resolutions - Run different resolutions on each monitor for those whom have a mis-matched set of screens.
Easily Configurable - Simple editing of custom input and output configurations via a USB connection to a PC.
Genlock - Auto-sense input and output frame rates, automatically genlocking when possible.
Low Latency - A delay of just 1 single video frame.


This would essentially be the first Displayport to DVI MST hub on the market, and if that was not good enough it is able to support PLP (Portrait, Landscape, Portrait) monitor configurations while supporting DirectX11! You could also use it with four projectors to create a 4k display for your home theatre.

The device will present itself to the operating system as a single large surface (aka 1 giant monitor), thus this will work on the windows desktop and in games without the need for any hacks such as SoftTH. It would also be GPU independent, and work with both AMD and NVIDIA cards.

What I would like to know is how much interest there is out there for this device, we really wish to make this happen but can only do so if we have enough interest so that we may get these devices produced for us. At present we expect the cost of such a device to be around £500-£600, however with enough interest we can bring this down.

If you would be interested in this device, please join the site (if you haven't already) and share your thoughts with us. I would like to start an active discussion on what you the community would really like to see from such a device, and how much you would be willing to spend. So, please help us help you!

I'd rather have DisplayPort to DisplayPort. Forget DVI.

seconded, displayport to multi displayport.

Converters for dislayport to hdmi/dvi/vga or available now , we are missing the displayport hub part.

Cool product! I can see the need for 2 models; DP out and DVI out. It would be nice to not to have to buy additional adapters to drive DVI displays. We use DVI>Fiber>DVI systems at work to drive projectors and displays at long distances. Having to add a dongle to the output of a DP hub would just add unnecessary complexity.
