The appearance of your computer's display can be influenced by several factors. The monitor you use and its settings, how Windows is configured, and how you use your computer can all have an effect on display quality.
To ensure that your monitor is calibrated correctly, check the instructions that came with your monitor.
Trying to run too many programs at the same time can cause display problems such as jittery or choppy video. If you notice erratic or reduced visual performance on your computer, try one or more of the actions described below.
Even if you have only a few programs running, some programs (such as video-editing programs) and features (such as high-definition television) use a lot of system resources. Running too many of these programs at the same time puts a strain on system resources and might degrade display quality or make video appear jittery or disconnected.
On some computers, very high resolutions require a lot of system resources to display properly. If you notice problems at high resolutions, try lowering the resolution until the problems disappear.
