Probably a firmware upgrade would do it, but I doubt they have an interface to update it.
Can you comment on the video image through DVI?

Right, the RGB and DVI cards can be easily upgraded by a swap.
The cards have serial computer input so firmware upgrade should be
possible if remote upgrade is possible at all. There is also standard computer monitor input both in the RGB and DVI cards.
Regarding the quality, the picture from the RGB is clearly an analog one.
To tune it properly one needs to set it like in a standard computer monitor,
height, width and centering.
We use Radeon 8500 and Matrox G550 for driving DVI. At the 1024x768 resolution the picture is 'pure' digital, razor sharp, no scaling or tuning. Computer fonts seen from close distance are exactly one pixel wide.
So DVI gives indeed the ultimate picture quality. With Radeon set to 1366x768 resolution we are able to see Windows XP in a 1024x768
window and even scroll the full picture within it. It is thus so pity that
Panny does not support full native resolution through the DVI.
How much this translates to a visible difference between the DVI and
RGB in standard viewing conditions is another question. At normal
viewing distance there is only minor difference in the sharpness of
pictures generated in computer.
With video there is normally scaling applied and this will have major
impact diminishing the difference between RGB and DVI.
When watching standard digital TV material at native resolution, there is perceived slight difference in sharpness between the RGB and DVI.
Ultimately though native DVI must be demanded for such expensive
display.
We would like to test HDTV in the 1280x720 in native format with no
scaling via DVI but we do not have access to such material in Europe.
