Default Re: Which NVIDIA Graphics Cards can display 2048x2048 ?

If your video card has a DVI-D output, then it should be possible to get
a VGA signal through a cheap DVI-to->VGA adaptor, but you need to
try it out to be sure (unfortunately, I don't have the necessary equipment
around, right now).

An RGB signal impedance missmatch most typically results in "shadows".
There are ready-to-buy impedance transformers available. Just google for
50:75 impedance transformer.

I have no practical experience with that product. Per Matrox, the maximum resolution
for the analog output is 2048x1536, but that doesn't necessarily mean a lot, i.e.
for nvidia cards the maximum resolution per output is 2560x1600, but I'm operating
my GTX 260 at 5040x1050 (per output).

For nvidia cards, it seems like you can program the timing values
(H/V visible, porch, sync and total) from 0 to 32767, so I'm almost
certain it should work. Also, my understanding is that wyvern666
reported success for his nvidia/barco combo, but I don't know
which exact card he used. Details about his setup would interesting.

It is possible to create "custom resolutions" with the nvidia configuration
tool that comes with the windows driver. However, I never tried that out
myself, so I can't tell for sure ...
