I’m having issues with both HDMI 2.1 ports on my AW3225QF with G-Sync enabled and monitor tech set to G-Sync Compatible in the NVIDIA Control Panel. While gaming on PC there is a lot of screen tearing at 240hz, and flickering at 120hz making it basically unusable at either refresh rate. This does not occur using DP 1.4, or with G-Sync disabled while using HDMI 2.1. I have tried different cables, the latest (and third latest) GPU driver, and I plan on trying a different monitor when I have one (on Thursday) to rule out a busted GPU (RTX 4090), but it’s not likely to be the case.

Has anyone else experienced a similar issue? I’ve reached out to Dell for an RMA just in case it’s not my GPU, but I’m concerned this could perhaps be a firmware issue.
