Video Card Problems causing distorted images display

My computer has a Radeon HD 4650 and 1GB video card. The video card is connected to DVI. My Samsung 23” Led monitor is also connected to DVI. So, the display must appear in my Samsung LED monitor. But unfortunately, I encountered a display problem. In addition to that, I also have a problem on my dropdowns. The dropdowns selections turn to black and white dots. The worst part of it, the whole display page turns to a black page with some distorted images. I don’t have enough knowledge about these gadgets making it more difficult for me to troubleshoot this. Can anyone tell me why am I having this can of difficulties? What are the remedies of this problem?

Video Card Problems causing distorted images display

HI

There are many things that can cause this problem. First make sure all the cable connections are firm. Remove and plug all the cables again. If your screen resolution is set higher than the level the DVI supports, problems such as the one you describe could arise. Look at the DVI manual for the supported resolution.

Make sure you have the correct monitor type selected in the Display settings. High refresh rate could also cause display problems, check this too in the Display properties. Connect directly to the monitor without using DVI to check whether it is the cause of the problem.

Reinstall the driver if the all of the above fails.
