I have a w2228h 23in hp monitor (FN747AA) and when. I plug it in the computer to the monitor i don't use hdmi it's the other cord with the pins. VGA. It used to work fine but now when I turn it on the screen appears and shows my desktop but then goes black also I used to take turns using the same VGA cord for both my desktops and one day one screen had a red line and green on the right of the desktop and anywhere else. Help me fix this. If I use a hdmi will that solve the problem, I think the VGA input spot is messed

If it goes black, it's a toss-up between the video card and the monitor. Strange patterns and lines are usually the video card.

It might be something simple like overheating due to dust. Turn it off, open it up, and take a look. Check everything you can before you spend money.
