Screen Resolution Suddenly Reduced

I have a Compaq Presario 2135US running Windows XP, with a Radeon IGP 340M graphics adapter. I have had my screen resolution set at 1280X1024 for years, but for unexplained reasons the maximum resolution available has been suddenly reduced to 1024X768. This happened after powering up from a full shut down. Does anyone have an idea what might be causing this and how it can be fixed?

Re: Screen Resolution Suddenly Reduced

Is the appropriate display driver still installed or did it revert to a generic graphics driver?

That would be the first place to look.

Re: Screen Resolution Suddenly Reduced

Do you have an external display or display adapter connected for video output or mirroring. That could cause the max resolution to reduce.
