Drivers & Software

[lajax]

Hi all. I need some help...

Given an LG C9 Oled, with premium hdmi 2.1 cables, pc with the following config: Ryzen5 3600, 32 gb 3600mhz ram, 650+ power supply, RX6800XT Nitro+ brand new vga, latest vga driver installed.

Its no matter what I try, I cant use 120 hz VRR... Under display, display specs shows 40-60hz refresh rate, VRR can be toggled, but only within this limited range... Its gave me a serious screen tearring with games.

Ps5, and Xbox Series X with same hdmi cable works just fine at 4k Hdr 120hz signal, with 10bit full range rgb.

With my old vga Rx570 8gb OC with HDMI2.0 output, I can use 4k 120hz VRR 10bit full range RGB, with some custom CRU display modification, with the same HDMI2.1 hdmi cable.

Any advice?

Thanks in advance.. LAJA X

SOLVED.

Whats done: with Display Driver Uninstaller, Ill remove everything, even PysiX.

After reboot, Win10 download barebone driver from MS server. Restart. In Windows Advanced Display menu, Ill enabled freesynch, and 120hz refresh rate, and disable DSU (see youtube) just to by sure...

Tested with some games, works as it should...

Then I install first AMD dedicated VGA driver (clean install): 22.5.2 -> Freesynch (stopped) not working again. 120hz reverted to 60hz. Pfff..

Then I install over it the latest to this date 22.11.2 (clean install).

After reboot, Freesynch worked again, refresh rate properly recognized.

Yeeeeeyy..

One last WARNING: _DONT ENABLE RSR_, it will stricht down your refresh rate between 40-60Hz!

Its weird, nowhere is mentioned this fact...

Thanks for nothing!
