Ok, I figured out how to restore the old version of the ATI Radeon HD3200 display driver when the Rollback Driver button is not available. Here's what I did:
- Download DriverStore Explorer from https://github.com/lostindark/DriverStoreExplorer/releases/tag/v0.8.4.2.
- Unzip and run DriverStore Explorer (Rapr.exe). The application displays a list of drivers stored in the \Windows\System32\DriveStore\FileRepository folder. On my PC, under Display Adapters are listed 3 AMD display adapter drivers:
c0317758.inf version=22.19.128.0 date=7/25/2017
c0317757.inf version=22.19.128.0 date=7/25/2017
c7179335.inf version=8.970.100.9001 date=1/13/2015
- In DriverStore Explorer, click Restart As Admin, select checkbox beside c0317758.inf and c0317757.inf, then click Delete Package.
- Start Device Manager and uninstall existing ATI Radeon HD3200 display driver.
- In Device Manager, select Scan for hardware changes; the old AMD display driver from 1/13/2015 should be re-installed allowing you to properly set the resolution of your display again.
NOTES: The AMD display driver should support all ATI Radeon HD3000 & HD4000 series display adapters. Since the drivers are provided by AMD, the fault for the problem likely resides with AMD and not MS. However, AMD may have intentionally removed support for the HD3000/4000 from the latest driver for some "unknown" reason.
