After years of AMD not supporting my PLP configuration, I just installed Windows 10 with Radeon 20.2.1. Great news! Eyefinity can FINALLY run on my hardware! (No more SoftTH for me!)
Bad news... there seems to be no option to adjust the bezel correction. I tried using offset feature in EyefinityPro.exe, but that doesn't seem to have any effect. Any ideas?
