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.
I changed all 3 monitors to 1920 x 1080 in Windows before turning on Eyefinity. Eyefinity gives 7680 x 1440 and does not give the 5760 x 1080 option.
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.
