I recently bought the above monitor refurbished from a company on eBay. The monitor worked great for about 10 minutes, I left to go to the bathroom, and came back, and my screen was completely white. Naturally, I did a monitor and computer reboot, which fixed the problem for approximately 10 seconds. Then, white vertical lines appeared through the screen, grew brighter and increased in number, until after about 20 seconds you couldn't even see anything on the screen except pure white. I rebooted again and the screen came through to my desktop wallpapers, but it was like everything was zoomed in and it was all very fuzzy and jumpy. Then the screen froze and everything before happened again (white lines). I have checked the cable and computer, and both are working fine. I have tried different HDMI ports, and a VGA port, all with the same result. Any suggestions, other than the obvious one of returning it?

So I unplugged everything on the monitor and let it sit for maybe 10 minutes, plugged it back in, and it works fine. Had to leave so I turned it back off. Is there any reason this should be happening? I just know that the next time I turn it on, it'll act up again.
