My screen resolution was fine at 1280x720. I restarted the computer and when it rebooted the screen resolution had gone to minimum. I opened display properties slid the slider to 1280 x 720 clicked apply but it just went straight back to minimum. I have tried following Microsoft trouble shooting which advised me to try finding a new driver for the monitor. Downloaded the latest version but the install wizard said it could not improve on the one installed. Help!!
Yes, this has cured the problem. However I am still concerned as to what caused it in the first place. I did an sfc /scannow and I think that this must have overwritten some files. It is the first time I have used this tool and I am surprised that it made alterations without notifying me.
