Custom Resolution Utility (CRU)

[ToastyX]

It works with Windows 8, but a few people have reported AMD's driver not picking up changes for some reason.

First, make sure you're editing the right entry. Check the drop-down list to see if there's another entry for your monitor.

If not, check the device manager to see if it shows anything unusual for the monitor.

GPU scaling won't affect higher than native resolutions, but toggling it might make the driver reload the monitor configuration.

If that doesn't help, try uninstalling and reinstalling the video driver.
