I've done a clean uninstall and reinstall of the latest driver for AMD on Windows 10 64bit for my (R9 390 8Gb) because I kept having visual corruption as if I had overclocked way too much my card, for no damn reason since I updated to that last driver... the cleaning fixed all of it, however here's my issue with the latest version of the (Pixel Clock Patcher 1.4.3)

If I apply it then reboot, my monitor (BenQ XL2730Z) that's 2560x1440 through Display Port at usualy 144Hz, well it won't have signal anymore and it remains black if I attempt using 144Hz... it will only work at 120Hz. If I remove the patch and reboot, it works again at 144Hz.

That's not a bug in the patch. The XL2730Z defines 2560x1440 @ 144 Hz twice for some reason, and the new HBlank patch is unlocking the first one. I don't know why they included that if the monitor can't handle it. Use CRU to edit the extension block and delete the first 2560x1440 @ 144 Hz (538.76 MHz). It should be using the 143.855 Hz (586.00 MHz) one.

What are you using the patch for? What limits were you encountering without the patch?
