For the life of me I cannot get my ACER 4k monito connected via DisplayPort and a generic 720 P monitor connected via HDMI to view in extended mode. I have tried 2 different HDMI monitors now and it just wont work. Both screens go black. It will work in every other mode (PC screen only, duplicate and second screen only).

 

I am running windows 10.

 

Under device manager I see the following under monitors.

 

Generic PnP Monitor

Generic PnP Monitor

 

BUT under the second one I find the following issue of this helps at all under events...

 

Device DISPLAY\ECM2000\5&921d474&0&UID260 was not migrated due to partial or ambiguous match.

 

Last Device Instance Id: DISPLAY\ADVEF2D\1&8713bca&0&UID0
Class Guid: {4d36e96e-e325-11ce-bfc1-08002be10318}
Location Path:
Migration Rank: 0xF000FFFF0000F100
Present: false
Status: 0xC0000719

 

I cannot for the life of me figure out why this won't work and it's frustrating the crap out of me. Thank you for your help!
