The right half of my monitor has become discolored and hazy with wobbling horizontal lines. I received the monitor as a gift last December, and it was working fine until this suddenly started happening a couple of months ago.
The S/N is CN-0KF87Y-74445-36B-EHLL (REV A00) (June 11, 2013)
Its a Dell monitor U2312HM 23 inch monitor. I've tried resetting to factory defaults but no effect. I have also checked cables and even plugged in my old monitor which worked fine, so its not my graphics card (an ATI Radeon) or DVI cable.
Is this a hardware fault? And is it possible to return/replace/fix this?
