When I did my fresh install of windows, both monitors briefly worked just fine until I had to restart my computer after installing the AMD drivers, so it is absolutely a driver issue.Primary is listed as Primary/Master/Discrete, secondary is listed as Linked/Discrete

The Radeon software DOES detect both graphics cards like normal.Thought that was related, so I reinstalled windows and the driver issue has persisted. I even did a startover on my windows 10 because I was running into issues with windows update not working. completely uninstalled drivers, restarted, unplugged secondary monitor, and plugged it in AFTER reinstalling drivers.disabled/reenabled both graphics cards through device manager.There's nothing wrong with the monitor or cable itself, as if I plug it into the primary graphics card to test it, it works fine. I'd fallen behind on updating my drivers (sat at 21.2-something for a while), and to troubleshoot some unrelated issues I was having with a game I was trying to run, I decided to update my drivers to 21.4.1.Įver since, my secondary monitor will NOT detect. I've never had any issues getting the secondary monitor to connect. I have two Radeon RX 480 graphics cards in my computer (no crossfire), and I've always used two monitors: both HDMI, one plugged into each graphics card. I'm just about ready to rip all of my hair out, so hopefully you guys can help me.
