Sometimes, it is not the picture or even the program causing issues. Video cards allow us to view pictures, games, and other images on our monitors. In some cases, the video card might be going out or simply needs to have its drivers updated.
The best way to determine whether your video card needs to be updated is using Windows Update if you are using a PC or checking with the maker of your card. If it does need to be updated, Windows update will notify you. Checking the maker's website from time to time is good too.
If your video card begins to go out, you can alternatively switch to another or that of your onboard video if you are using an external card. Fortunately, video cards have gone down in price and should not cost more than $70 at most should you require a new one. In addition, monitors also can go out, especially the old CRT ones. If your screen lights up in blue or green, it is a sign that one of the bulbs has gone out. The only solution is to purchase another monitor.
As with video cards, monitors have also gone down in price, especially LCD monitors. A 19-inch can be bought for a little under $100, while larger ones can cost up to $500.
