The PG27UCDM is specified with a G‑SYNC/VRR range of 48–240 Hz. However, Low Framerate Compensation (LFC) is engaging at 60 Hz, even though the VRR floor is listed as 48 Hz. This behavior can be observed directly using the PG27UCDM’s built‑in OSD FPS...
After extensive testing on the PG27UCDM, I’ve observed that VRR (Variable Refresh Rate) does not engage below 60Hz, despite the monitor’s EDID and official documentation stating a VRR range of 48Hz to 240Hz. This behavior persists across multiple set...
There is an issue with this monitor with flickering and blanking when G-sync is enabled causing the safety measures to kick in to prevent damage.
I believe that is why the screen is not Validated by NVIDIA yet as this screen cannot pass the tests.

For some reason my Z790 Hero when I have everything at default with MultiCore Enhancement disabled my 13900KS is not sticking to it's default PL1 and PL2 Limit as it is setting both of the limits to 320.0W.I can not get the chip to run at stock could...
I know there is a thread with another person having same issue on the rog forums but I feel it should be brought up in here since it would be helpful to get more information on this There is an issue on the Z790 Hero that when you leave PCIe Native P...
It is much easier for the monitor to do because I think there is a rule that Adaptive sync has which is somthing like
Max Refresh Rate must be ≥ 2.5 × Min VRR Refresh Rate
so 120 Hz max → 120 /2.5 = 48 Hz minimum VRR
so for a 240Hz the minimum to ...

PG27UCDM – VRR/LFC Behaviour at 120 Hz (Test Findings)
Refresh rate configuration: The PG27UCDM cannot be set to 140 Hz, but it can be set to 120 Hz without issue.
Observed VRR/LFC behaviour at 120 Hz:
With the monitor running at 120 Hz, setting a 5...
