3. If you're noticing a constant flicker on your CRT screen, check the refresh rate. Tick 'Hide modes that this monitor cannot display', then select the highest number in the 'Screen refresh rate' drop-down list. For an LCD monitor, there's no advantage to setting the refresh rate above 60Hz.
4. Now click the Color Management tab. Colour management is useful in calibrating your monitor and printer to achieve consistent colour — what you see is what you print. No profile is assigned by default. Click Add to select one. Good profiles to start with are the widely used sRGB or Adobe RGB.
5. The software supplied with your graphics card offers further control over your display. We're using ATI's Catalyst Control Center, but the equivalent nVidia utility offers similar functions. Open Catalyst and select Displays Manager. Here you can set resolution, colour depth and refresh rate from the same screen.
