- Hanns G HW173A monitor
- NVIDIA GTX 460 graphics card
- Windows XP SP3.
It was working. Suddenly overnight I can no longer use my monitor's native resolution of 1440x900. It's not listed, and if I force it it only shows part of the screen. The only resolution that seems to fit the whole screen is now 1024x768.
I have tried reinstalling the NVIDIA drivers as well as disabling and enabling the monitor drivers (for windows XP the monitor uses the microsoft "default monitor" drivers - this is what Hanns G says on their website too).
Any ideas? Thanks very much.
update: solved by completely removing the VGA cable then putting it back. Must have been loose.
