Monitor not waking up properly

[robisc]

When PC goes to sleep my monitor won't wake up properly, it's got vertical colored lines all over it, sometimes if I unplug it and plug back in it works, any ideas?

Could also be your video card not waking up ahead of the monitor.

Thanks for replying and yes I thought that too not sure what to do with it besides a driver update which I did but didn't fix it.

Look in BIOS for display related setting options for an inappropriate setting:
:
- Video Memory Cache Mode [UC/USWC]
- Video Off Option [Suspend -> Off]
- Video Off Method [DPMS Off]


This last mode allows the BIOS to control the video display card if it supports te DPMS feature.
