Video display problems can be pinpointed to a cable defect, connector defect or video card defect. Though rare, it can also indicate a problem with the monitor itself.
Your monitor receives display signals from the video controller, which can be in the form of on-board graphics or a separate graphic card.
- Make sure the graphic card is firmly connected in the motherboard slot. If it is loose, it can cause artifacts on your screen.
- Always update your graphic card drivers to the latest manufacturer version, to maintain audio-video & motion graphics performance.
- Some monitors are also affected by electromagnetic interference. Keep such devices (transformers & home appliances) away from your monitor neighborhood.
