How do I know if I need a new computer monitor or a new video card?
My computer monitor is flickering and the colors are awful with vertical lines throughout. Do I need a new monitor or a new video card?

First test to see if the connection cable between each of them is good, blow some air into it to and try plugging it in. If that doesn't work, try testing out each one. Test out the moniter by hooking it up to another computer. If it works, then moniter is good, test the cable, then the video card.

hi...

Awful color may be caused by a loose connection on the cable... check that please.... if that doesn't help, continue on

Right click an empty area of your desktop, select Properties >> Settings >> Advance >> Monitor

At the refresh rate, the default is 60Hz, this may not be what currently selected. Continue to change this value higher and click Apply, but 1 level at a time.... the higher it can get, the more stable your monitor picture is....

If the rate is changed to a value too high that the monitor cannot take, you will not see anything on the screen, do not panic... in 10-15 seconds, it will automatically reverse to the previous settings... or you can just press ESC to take it back anytime.

Vertical lines seem to be a monitor problem, not video card... if you have another computer nearby, swap that monitor with this computer... if the other monitor works ok with this computer, you definitely need another monitor...

g'luck!
