This issue is with your monitor, not PC.
Disable sleep function should fix the issue.
Try switching off PCIe Link State Power Management under Power Options>Change plan settings>Change advanced power settings>PCI Express. I found it worked for me.

Yup I don't think it will. I think the problem is with the drivers controlling the ZeroCore power management thing where it can switch off the graphics card or something like that. It just can't start again once its switched off.![]()
I've encountered the problem intermittently on my desktop before. My situation wasn't related to the monitor. Resolved by turning off power at the power point and turning it back on after a while. Googled it and found it to be a fairly common problem.
