I currently have three monitors connected to my Radeon R290. Two are connected via DVI/HDMI, and one is connected via Displayport via an active adapter Diplayport/HDMI adapter. This set-up has worked perfectly for just over two years. This morning, my computer froze (cause unknown), and when I rebooted it, I got an error notification saying there is a link failure, and that there was an issue with the requested resolution/refresh rate.
I've been working at this for a couple hours and can't seem to fix it.
I'm running Windows 10.
I haven't made any hardware or software changes.
I've tried the usual unplugging/replugging/cable swapping/rebooting
Any suggestions? I don't even know what the relevant issues to examine are for this sort of problem.
Thanks in advance!
