I have a 17" Samsung Syncmaster 793DF that I bought this May.
Red horizontal lines are constantly appearing and I don't know what it is.
It first started happening about a month after I bought it, and it appears near the right side of the screen. By tilting the whole monitor left (lifting the right side), the lines would disappear. But lately it's been happening frequently and gets so bad that I can't even read text. It's not my video card because I've tried attaching it to another computer and it still happens.
Any info on what causes this and potential fixes would be appreciated.
