I have recently purchased a Digimate L1715 16ms Multimedia 17" TFT monitor.  I want to run it on my microATX with m/b Gigabyte GA-8I915G-MF with onboard Intel GMA 900 ( 224 MB ) - Dynamic Video Memory Technology 3.0.

I built the system with XP Pro and everything seemed to work fine.  I changed the graphics seetings to something well within the range of the graphics adapter and monitor and got a perfectly good image output...

I rebooted, and on boot - right from the bios screen - the image was scrambled in disjointed horizontal lines spanning the screen.  Hitting F8 made no difference as the image was already scambled before entering windows.  to get an image I had to put my old CRT on the machine and then it booted up fine with a good image output.

I subsequently went onto the Gigabyte website and downloaded the latest drivers for the graphics adapter and installed these. Rebboted and everyting was OK.  Installed some more software and another reboot and to my horror - a scambled screen, exactly as before in bios which persisted into windows.  Again, further reboots did not help, but putting the old CRT screen on works.

Can anyone explain what is going on?  I think it must be a dodgy monitor, because of the scrambling before windows?  Or is it a conflict between the monitor and the onboard grahics?  Any advise would be greatly appreciated.

Thanks.
