win 10 hdmi ports go away

Question asked by adpena53 on Oct 27, 2015

I'm running Windows 10

 

Monitors stop working I have two cards: 1 HD 6570, 1 R7 200 Series

 

 

I have 4 monitors, connect via VGA and HDMI (using VGA to HDMI adapters).  I have uninstalled and reinstalled drivers.

 

 

This has been a working config, but I sporadically lose my ports where only 2 or 3 monitors work. What is really weird is that depending on which card I "disable" in device manager, the actual monitor/ports that work change.

 

With both cards enabled only 2 monitors work. If I disable one of the cards, 3 ports work???

 

So I know that all the monitors and cables are fine because at some point they all work independently. I've accidentally resolved this by re-seating the cards and rebooting in the past.

 

Please help!
