LCD-Problem

[GUIDO HOCHULI]

Hallo
I've got a Targa-PC with a Nvidia Gforce 6600GT graphiccard 64 Bit,
connected to a Targa 19"-LCD-Monitor on DVI. Both from the
"lidl"-Store in Germany.
All running now on Ubuntu 6.06
I can only set 1024x768 and not the desired 1280x1024 on my LCD.
On start-page, before installing, I set 1280x1024. I tried 16 and 32
color mode with no better result than 1024x768.
Is there a possibility to change the screen to the higher resolution.

Thank you for thinking over the problem.

Yours very truly
