Vertical Red Lines/Dots (not video card)

post #1 of 3
Thread Starter 
Samsung 2333SW using DVI

Bad pic, imagine the blurry red stuff is vertical lines and dots situated like |||||||||||


Every once in awhile my monitor shows red lines/dots that seem to magnet to any gradients or a few odd solid colors here an there (not sure how it selects its victim). They go away sometimes in about 2mins others it takes 30mins, then disappear for months. Sometimes it will go away if I shake the DVI cable a bit and others I have to unplug it or reboot the computer and even then it doesn't always solve it. It's completely random when it happens. Could be minimizing Firefox or closing an explorer window then all of a sudden they're everywhere.

It only really bugs me when it doesn't go away. I've swapped the DVI cable with another that shouldn't produce this problem. Both came with their respective monitors, same no-name brand, and feel pretty flimsy. Still does it... probably not definitive evidence considering they are exactly the same though.

Also the monitor was bought from Overstock.com refurbished, so not sure how that would effect warranty's and such if its the monitor itself at fault.

Have you tried a completely different type of monitor all together?

Yes, said it wasn't the video card. Whatever it is is between the video card DVI out and the picture I see on the screen.

Just tried VGA as well and it just makes the dots more annoying (they flicker more).

Edit: Took about 3hrs to go away today... thought whatever it is causing it finally bit the dust. Just went away while I was reading some oblivion modding articles (quite long ones... no clue when it went away exactly). Forgot to mention I also tried the monitor on another computer and it had the same problem (reinforcing that its not my GPU). Probably going to see if I can RMA it. Registered it on Samsung's site and the email said I got 3 months warranty free.
