VRR not working on 2024 LG Gram Pro 16

Talk about AMD's FreeSync and VESA AdaptiveSync, which are variable refresh rate technologies. They also eliminate stutters, and eliminate tearing. List of FreeSync Monitors.

VRR not working on 2024 LG Gram Pro 16

Post by KWottrich » 23 Jan 2025, 13:56

I have the 2024 LG Gram Pro 16, which is equipped with the Intel i7 155H, and does not have a dedicated Nvidia GPU onboard. The screen is a 2880x1800 OLED display with a 120Hz refresh rate connected via eDP, and the hardware ID of the display is SDC41A5. I am running Windows 11 Pro 24H2, and I have Intel Graphics Driver 32.0.101.6458 installed (which I downloaded from the Intel website after deleting all older versions of the drivers with DDU).

My problem is that Windows and the Intel Graphics Software both report that my display is VRR-capable, and I have enabled the feature everywhere I can find, but I still experience significant stuttering during games as though VRR is not working.

As a note, I have tried enabling and disabling the "Dynamic refresh rate" setting in the Windows Advanced Display settings, but the stuttering persists in both cases.

I am using Nixola's VRRTest tool to easily verify the stuttering, although I experience the stuttering in every game I try, as well as when using Moonlight to stream from another PC.

Any help would be appreciated! Let me know if there's any other information I can provide, or configuration changes to test. Thank you!
