My son has a new Samsung 204b lcd monitor and via DVI the PC (with XP)
is not recognizing the monitors native resolution of 1600*1200. Nvidia
control panel shows native res as 1280*1024 for some reason.

He runs a 7900gs card and I have confirmed this occurring also on my Pc
with a 8800GTX card and Vista

We have tried 3 different video divers, 2 different DVI cables and still
cannot see the native res.

On vga/analogue cable the res shows up.

Any1 seen this happen before and if so what is the cause/solution.

This program will display the EDID information coming from the monitor.

The description of the program is he
http://www.entechtaiwan.com/util/index.shtm

"Monitor Asset Manager serves a dual purpose. Free for personal use,
MonInfo captures and translates all the data passed by the monitor
to the display driver and on to the operating system - revealing,
for example, the reasons behind limitations on resolution and refresh
rate, and the monitor manufacturer's recommended timings."

As I understand it, installing the "monitor driver" from the monitor
maker, can declare more resolutions. Since my EDID seems to be OK,
I cannot experiment with that.

On some older video cards with DVI, the higher resolutions were not
available because of issues with the max clock rate of the DVI interface.
Some DVI interfaces could not run at the full rate, and rather than
end users seeing snow on their monitors, the driver limits the rate.
I doubt that is the problem with your setup, as you have recent and
high end cards.

This article has some interesting background info.
