Hi everyone. Thanks in advance for your help.
u2713HM sudden screen problems -- squares and backlighting.
As instructed in the monitor sticky, I have tried factory reset and built in diagnostics.
Using the built in diagnostics I believe i have ruled out the PC, however just in case it is -- Windows 7, Asus GTX 780, and using a DVI-D cable. It is a custom PC so no model number.
