Poor Display Quality

Poor display quality can lead to a very unpleasant experience as well as eyestrain. Short of having a faulty monitor or graphics card, a poor-quality display is almost invariably caused by a problem with graphics card drivers or by using an unsuitable display resolution. Follow these troubleshooting tips to get your computer's display looking as it should again.

1 - Check the Screen Resolution
Flat-screen monitors have a native resolution which they display best. Using another resolution, while possible, will not look good and can even lead to more severe display problems. You should always have your monitor set to the native resolution wherever possible.
Right-click on your desktop and click "Screen Resolution." Choose the recommended screen resolution for your monitor. This is the same as the native resolution, provided you have the correct graphics card drivers installed. Click "OK" to save your changes. The screen will flicker on and off for a few moments as it changes the resolution. If the display does not look better, proceed to the next step.

2 - Install New Graphics Card Drivers
Windows 7 will normally only display the correct resolution for your monitor if you have suitable graphics card drivers installed. If Windows 7 does not detect any graphics card drivers, it will install generic ones of its own instead. These drivers are only suitable as a temporary solution, allowing you to use the computer effectively enough to download and install the correct drivers.
It's a good idea to use the latest drivers available for your device. This means not using the drivers on the CD which came with your computer or graphics card. Instead, find out which type of graphics card you have and download the latest drivers for it. All graphics cards are either based on nVidia or ATI chipsets, except for integrated ones of which there are a variety of manufacturers.
Download and install the latest graphics card drivers. nVidia and ATI both provide unified driver packages which are compatible with whole ranges of products, so it doesn't even matter if you don't know exactly which model of graphics card you have. You will need to ensure that you download 32- or 64-bit drivers for the correct version of Windows, however.
