If the resolutions do not appear after a reboot, the following may fix the problem.
- Open Registry Editor (regedit)
- Select "Yes" when it asks if you want to make changes to your device
- Navigate to
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}. You can also paste this into the header and press Enter on a keyboard or A on the controller
- Look for any subkeys (folder icons) with an expansion arrow
- You don't need to expand them, just click the key and scroll through the panel on the right until you find one which has a 'DriverDesc' of 'AMD Radeon Graphics' (the name may also have a model number if you aren't using the official ally drivers).
-
Make a note of the 4-character folder you found the value in. It's most likely to be '0001', '0020' or '0021'.
-
Download the registry file containing the resolutions you want from https://github.com/AllyPal/Rog-Ally-Custom-Resolutions/releases
-
Right-click the file you downloaded, select
Open with, and choose Notepad (or your favorite text editor). You may get a security warning -
On the 3rd line, replace 0000 with the 4 characters you noted earlier (e.g. 0001, 0020, 0021)
- Save the file, run it and reboot
