Just in case this wasn't posted.

Matrox Graphics DualHead2Go goes digital
The Matrox DualHead2Go is already available using traditional VGA connectors. The just announced DualHead2Go features digital outputs.It also enables support for high-resolution panels, offering a stretched desktop of up to 3840x1200 (or dual 1920x1200) across two displays. Available in Q1 2007, DualHead2Go Digital Edition has a manufacturer's suggested retail price of US$229.

I wonder how far a new TH2Go can be?

TH2Go digital would be awesome. I can't wait till 5760 x 1200 will become available. :P

Will digital TH2G allow 3 x 1920 x 1200 (ie three 24" widescreen lcd mon) ?
I dont recall offhand the peripheral vision of human eyes (how many degrees? 200 degrees?).
So, if you use 3 x 1920 x 1200, would this view exceed 200 degrees and so give you supernatural peripheral vision in FPS games like FEAR?

Can we (ie WSGF) sort this fact out so we all KNOW what optimal viewing angle would be for the human brain/eye/sensors.

I did some quick search in the web and it appears 180-200 degrees range is the limit. And I just confirm this range with a little experiment of my own. :-)

And Matrox says the TH2G at 3 x 1280 x 1024 gives 135 degrees field of vision. So, can someone do the math and convert 3 x 1920 x 1200 to degrees of arc and see if this is below or above the field of vision of a pair of human eyes?

There isnÃ¢â‚¬â„¢t a game or a video driver that will allow you to display 3D graphics on such scale even if Matrox game us the capability.

While this is exciting news, everybody can stop getting their hopes up for crazy high resolutions on a digital TH2Go. To further build on RUS007's statement, Matrox said on their old forum that no video card in existence supports 3D in resolutions higher than 4096 per side. Its a limitation of how GPU's are programmed, they simply cannot display any more pixels in 3D. Its similar to old limitations on texture sizes... remember when cards couldn't do textures bigger than 1024x1024 for example? Same thing... its hardwired in the silicon, only nvidia/ati can change it.

3840x1024 is the highest resolution we're going to see in triple-head.

Maybe there will be only a digital DH version :(

Interesting ... while I was looking at the product shots of the DH2G I noticed while the outputs are DVI the input is still Analog. I wander why?!?!

For compatibility reason DH2Go Digital, still handles analog input only, not digital. It is the output of DH2Go that has the option of DVI/vga output, As 400Mhz RAMDAC analog vga outputs are most easily available.

Most analog 400MHz RAMDACs states 2048 x1536 x85Hz x32bit limit, I guess with 3840x1200x60MHz x24bit/32bit, it is within the limits/exceed it a little.

1920x1200x60Hzx24bit x2 is also the limit of DL-DVI can support...which is at 4.6 Mpixels. HDMI 1.3 exceed DL-DVI bandwidth by by a little, so it maybe able to replace DL-DVI with the same amount of connection/pins as SL-DVI.

Therefore, there will unlikely any products be able to push 5760x1200 (6.9 Mpixels) at 60Hz from one output now or in the immediate future. If you reduce the refresh rate Hz of the display you could increase the resolution further ... for example you can power 3840x2400 (9.2 Mpixels) resolution with SL-DVI by reducing the refresh rate to 18Hz...

Yes, but The NVIDIA 8800 (and more importantly) DX10 may have changed this...

WHo knows if MS sees a reason for this....

Yes DirectX 10 is capable of delivering double the texture size of DirectX 9, but like I said earlier .........

Because the DualHead2Go a product designed to be used with laptops. Most laptops do not have DVI connections.

Hmm... thats a good point

As long there will be no TH2GO DVI it is uninteresting.

Well, first Matrox made an analogue DualHead2Go. Then they made an analogue TripleHead2Go. After that they made a digital DualHead2Go.

Seems to me the next logical step is a digital TripleHead2Go...

it makes more sense using tripple widescreen in portrait mode , than 3x landscape....
can TH2Go handle 3x rotated screens?
