Di, you do not say if it's a CRT, flat panel or laptop screen.
Assuming that it is for a PC the first thing I would do is dis and reconnect the monitor video out cable - at both ends if that is the type. If that makes no difference then you are in to all the things that you have probably done - set the monitor to Auto, set the resolution on the graphics card to different ones available and also try different refresh rates, check the brightness level. Check Windows' power options/settings, font smoothing/clear type, visual effects and Display properties, maybe try new graphic card drivers.
