Hi,
I'm trying to set a custom refresh rate for one of my displays, but I get the error message "the resolution is not supported". I think the problem is that when I click the create custom resolution button in the settings, the custom settings are not filled in like they were with the older driver where I only had to change the refresh rate.
My specs:
Gigabyte Aorus X470 Ultra Gaming
Ryzen 5 2600X
G.Skill Trident Z 2x8Gb DDR4 3000MHz
Asus Strix R9 390X
Check your computer 'advanced' settings in Display. Make sure it's not set to 59hz.
Try to change the language of Radeon Settings to english and try again.
