Need custom resolution options for Eyefinity in 2020 Drivers (20.1.3)

Discussion created by djbully on Jan 27, 2020

Hi Everyone,

                    I am having real issues trying to get a 3x1 eyefinity setup going here. It used to work so well, but lately 3 screen eyefinity has been RUBBISH! AMD used to own this segment. AMD Eyefinity was the benchmark for other's to follow with regard to multi-monitor setups. How has it come to this? 


Anyway, I'm not here to bash. But I would like to get multi-monitor working sufficiently again. 


My setup:

AMD 3900X in Asus Crosshair VI Hero (Windows 10 Pro x64 1909)

32GB(2x16gb) G.Skill Trident Z 3000C14 @ 3600C16

Asrock "Phantom Gaming" Radeon VII 16GB HBM2 Driver 20.1.3

3 x iiyama G-Master GB2888UHSU 4K 3840 x 2160 @ 60Hz Display-Port Freesync

EVGA 1000W Supernova Platinum PSU

I also have 2 Vega 64 LC kicking around, but Xfire is not worth it, that's another story.


As you can see, I've spent a lot of money to have a nice multi-monitor setup ££££'s


Ok, so my native resolution is 4k 3840 x 2160. 


I finally managed to find Eyefinity quick setup in the new GUI, I had to disable live streaming (which I wont use anyway) and then the Eyefinity option appeared in settings/display. 


I also found that Eyefinity Pro app that is hidden in the CNext folder of the driver. I was able to use that to get bezel correction, I found a nice setting and that was as it should be. 


So now, here's the thing. I used to be able to set a custom resolution in the old driver. Like I said, native resolution is 3840 x 2160. So if I let Eyefinity do it's thing it creates a group with 3 x 4k resolution (11560 x 2160). With bezel correction it was 11720 x 2160. 


Ok thats fine, and sat on the desktop, its fine. No problem. As soon as I try to load a game it just insta Blue Screens. 


Now it used to do that quite often if I tried to run an intensive 3d game at ridiculous resolution (11720 x 2160)


So used to set a lower resolution like 7680 x 1440 or 5760 x 1080. You could only use one at a time, but that was fine. Pretty much every game would run decently @ 7680 x 1440. 


But I cant find how to do this on this latest driver. Please does anyone know where this is? 


The display settings page shows a "custom resolution" option with no Eyefinity group. But as soon as you create an Eyefinity group that option disappears!  I am really stumped! 


All I want to do is play Euro Truck Simulator 2, with 3 screens, wheel + pedals + gearstick and head tracking. 


Is that too much to ask?


Thanks in advance if anyone has any solutions!
