Ive had a two monitor setup for 2 years i just updated my video drivers and now my computer refuses to recognize my second monitor. I have two radeon r9 saphires running in crossfire. Ive spent 2 hours on google looking for a fix and found nothing any help would be great. It just wont see the second monitor plugged in. They are both Hdmi cables.
Are both monitors showing in device manager?
Press the Windows Key + P and try to duplicate/extend the displays.
