Hello. I have problem with my 3 monitors setup. I'm using Radeon RX 480 and 16.9.2 software on Windows 7 64. The point is whenever I update my drivers to the new version (18.11.2-nov19 for example) and then enable eyefinity mode, my cursor start to lag and hangs for couple seconds. Also one of my monitor on displayport going to sleep. I tried to power it on and off but it doesnt work at all. Is there any way to fix that problem?
read this thread. AMD Radeon Software 18.5.1 freezes my computer every 5 seconds It might be the same thing.
I've stuck with 18.3.4. until this issue is fixed and eyefinity is working normally with this slightly older version.
Another option is to disable HDCP... details in the above thread.
