Display off screen with Dell 26" TFT and Radeon 1800XL

hi,

I hope someone might have a suggestion as to cause of this odd issue. My display (including boot/BIOS) is off the edge of the screen on my Dell 26" TFT but fine on my Sony 24" CRT. I tried reversing the connections, but the same result. I therefore think the card is OK as the CRT displays fine from either output. The Dell seems fully functional other than the anormaly. Anyone know a reason for this type of behaviour and a resolution?

The card did display poorly at boot but this was an issue between the Nforce 4 and the ATI card, which required DotNet to fix. The BIOS update seemed to fix this, as the boot screen is now normal - but off the edge.
Could it be a BIOS issue?

The board is the Asus A8N Premium.

Thanks to all

Stupid question, but you have hit the button on the TFT to "auto size" for that res havent you?

Check the resolution is set to default. Probably 1280x1024.

I had the same problem when building a rig for a mate and that was why.

Will check - could not see an auto fit - reset to defaults,but no change.

Will have another look.

The issue cannot be Windows - must be the TFT settings...

Solved. There was no auto resize, but changing the dvi source from auto to pc fixed it.

Thanks.
