Eyefinity down resolution to 1080

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.

Re: Eyefinity down resolution to 1080

  1. Can you send a screenshot from all available resolutions?
  2. What is the refresh rate and bpc set to?
  3. What are the cables and adapters you are using?

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.

Change your refresh rate to 60Hz and try again

I tried 59 Hz, 60 Hz, 75 Hz.  None works better with Eyefinity.

Re: Eyefinity down resolution to 1080

I found a workaround from user ets post.

https://community.amd.com/t5/graphics/eyefinity-advanced/td-p/317755

 

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.
