I have 3 monitors 2560 x 1440. I want to connect them to give 5760 x 1080 for faster gaming frames. Eyefinity gives 7680 x 1440 and some 768 options. It does not allow custom resolution even I tried EyefinityPro. How do I make 5760 x 1080 with Eyefinity? I use Radeon 21.4.1.
Before you apply Eyefinity, you need to assign1920x1080 resolution to each individual display. Once you established that, then you can create Eyefinity screen.
Refresh rate is 75 Hz. 8 bpc.
Cable to the 3 identical monitors are HDMI, DP, DP straight cables. Eyefinity makes no difference if I change their resolutions to 1920 x 1080 before Eyefinity or leave them at 2560 x 1440.
I found a workaround from user ets post.
Downgrade to driver 20.3.1. Turn on Eyefinity. Then run ccc.exe. That app can customize Eyefinity to 5760 x 1080.
This kind of solve my problem but I can't use any new release because none of the new drivers has ccc.exe anymore.
