AMD/ATI Pixel Clock Patcher

This should work: https://www.monitortests.com/atikmdag-patcher-1.4.1.zip

If you used the old 1.3.6 patcher, you'll have to run it three times to patch it the new way. The first time, it will just fix the low-resolution limit and leave everything else alone. The second time, it will restore from backup. The third time, it will patch the new way. You only need to reboot after the third time.
