Stuttering on PS5 with new 4K Monitor

I’ve just upgraded from a 24” 2K 60hz monitor to an AOC U27G4R 4K Ultra HD 27" Fast IPS Dual-Mode Monitor. I’m on base PS5.

Arc used to run beautifully on my previous monitor, but this monitor has introduced a lot of stutters, noticeably when sprinting.

I’ve got VRR on auto, 120hz auto, HDR auto, 4K resolution, and HDMI 2.1. Even when I turn these off, the issue seems to remain.

Has anyone had something similar happen, or can anyone offer advice? Thanks!
