For some reason adjusting a 1280x1024, 32 bit @60hz image messes up my average desktop res of 1600x1200@85hz on my sony monitor. Other resolutions seem fine, but as some games will only allow you to go up to 1280x1024 (ms motocross madness 2 for example) it's a pain in the arse. It is to be expected though, as i think i've probably saved 15 or so different refresh rates in that monitor already.
But there is a fix. If you have a nvidia card with 40 series drivers then go into display properties and use the override refresh rates control (see image attached). Just mess around with the settings until you find an acceptable refresh rate that displays properly at the resolution you want to use.
