What type of monitor is this? If it is an LCD screen, you may have some dead pixels. Please reply with some more details about your specific monitor.

the lcd is bad,for some strange reason this is becoming common with Imacs.I recently repaired about 30 with the same problem.The techs at apple wont say why this is hapening they prefer to replace parts.In your case you will have to replace the lcd display and the cable from the display to the logicboard and not the logicboard.

Linear defects of this sort can be caused by a faulty display cable, a faulty LCD panel, or a faulty connector between the two. Much less likely is a problem with your graphic processor, since the line is static in appearance and position. Unless your Mac guy has lots of spare parts hanging around, I would suggest you replace the cable first, as it is the least expensive fix. If that doesn't do the job, then the display panel must be replaced.

Yep, you can clean the LCD and the inside of the glass, but you will need two suction cups for glass. The ones for picking up window glass work. Lay the computer on its back. Place the suction cups at the upper corners and pull straight away from the table. The glass is held on by magnets and may have tabs at the bottom, so once the magnets are loose you may have to lift the glass away from the bottom edge. Be careful, it isn't safety glass and can break if dropped. The hardest part is keeping dust from getting between the screen and the glass during reassembly. Try working in a dust-free environment. I use two micro-fiber cloths, one with screen cleaner and one dry. You can't believe how much static builds up on the inside of the glass. It just sucks in dust. Don't wear fleece or you'll end up with fuzz as well. Stand your iMac up to reinstall. Clean the outside of the glass so you can see any dust on the inside. Place the bottom in place first. As you prepare to move the top into place, have light behind and above you and view the glass with the black screen behind. You can see most of the dust that way. Good luck.
