Is my monitor or video card about to go? |
|
I'm seeing small barely visible horizontal static lines running down the screen.
I remember seeing this on my computers in the past as they aged, and it was usually around the time I replaced the computer. I don't really want to replace this one because I have so much crap on it, and had the harddrive replaced just a few years ago. The computer is 8 years old, so I'm surprised it's kicking the bucket.
Any ideas?

1. Is it a CRT (tube) monitor? |
|
Do the lines "move" up and down the monitor?
If so then likely it is an issue w/ monitor and not your computer. CRT "draw" the screen one line at a time as they age the electron gun slowly goes out of alignment. The "line" you are seeing is electron gun slightly overdrawing the screen. i.e instead of moving down 1 full line it is overlapping and moving down 0.98 of a line. After enough lines that error adds up and it overdraws an existing line creating an artifact.
Nice news in LCD monitors are cheap. Likely you can get a better, higher resolution monitor that is lighter and wastes less energy (heat) than your old CRT.
Buy a good monitor and you can keep it and use it on your next computer system also.

It is an old fashioned tv type monitor. I kind of figured it was going because when the computer is in sleep mode and the screen is black, and I move the mouse to activate the monitor, it takes a while to light up.
The problem is exactly how you describe it, with the lines moving down the screen. Your explanation makes so much sense!

3. DeGauss your CRT May give it a needed boost. Do not open that CRT up, those condensers can |

discharge a killing jolt. < http://www.wikihow.com/Degauss-a-Computer-Monitor> I only use the menu button method.
