Customer Question

There are all these vertical lines across my computer screen. They just appeared and it makes it difficult to see my screen in this section. Is there anything that can be done about it?

Is this on a laptop?

Customer: replied 5 years ago.
It is not a laptop. This is my desktop computer
Expert:  Adam replied 5 years ago.
Is the monitor LCD?
Customer: replied 5 years ago.
Yes it is.
Expert:  Adam replied 5 years ago.

Have you tried any other inputs on the LCD monitor (if it has more then one)?


Also, can you try another computer with the screen to make sure it is not a computer issue?

Customer: replied 5 years ago.
Do you know anything about Macs? The screen is not a separate monitor. The computer and monitor are all in one.

Most have the ability to connect to another video source VIA a RGB cable but I will look that up when I know what MAC computer this is.

OK, thanks for trying.

No problem, I could not find much about that MAC online besides pictures of them on google. (Haha)
