Radeon R9 280X Triple Monitor Solution

5 posts in this topic

Recommended Posts

I finally managed to get all three of my monitors working with my Radeon R9 280X (model ASUS-R9280X-DC2T-3GD5). Previously, using more than 2 monitors would result in my system freezing until I unplugged one of the outputs. After trying patched framebuffers and a variety of different port configurations I finally solved my problem!

 

It turns out the solution was to switch to using the card in UEFI GOP mode. To accomplish this you need to be using Clover in UEFI mode (not CloverEFI), and your motherboard needs to be set so that the GPU runs in UEFI GOP mode. On my motherboard this meant disabling CSM.

 

My system now runs great with all three monitors, either using GraphicsEnabler=No or GraphicsEnabler=Yes along with a patched framebuffer. This may also work for other AMD cards that exhibit similar behaviour when used with three monitors.

Could you detail how to set it up? I want to try it with my R9 270 with my dual monitor. Currently only one monitor work (@ 2560x1440) either via HDMI or DVID but not both as the same time.

      I know that it is almost impossible to install any os x on AMD APU netbooks, but i am hoping that  someone could help me here. Any help would be greatly appreciated.
      Thank you
