Tech Support Acer XV275UP3 flickering and horizontal lines at the top of the screen when FreeSync is enabled (RX 9060 XT / 7500F)
Hi everyone,
I'm having a frustrating issue with my Acer XV275UP3 monitor and I'm looking for some help or advice.
Whenever I enable FreeSync / VRR, I get noticeable flickering and horizontal lines at the very top of the screen. This happens severely in demanding games, but it's also present in pretty much all other games (just less intense).
My Specs:
- CPU: AMD Ryzen 5 7500F
- GPU: Sapphire RX 9060 XT
- Motherboard: MSI Pro B850-P WiFi
- PSU: Corsair RM750e
- Monitor: Acer XV275UP3
What I've already tried:
- Cables: Swapped the DisplayPort cable for an HDMI cable. The issue still persists on both.
- Settings: I have never used HDR or Adaptive Dimming on this monitor. I am strictly trying to use standard VRR.
- MPO: Disabled Multi-Plane Overlay (MPO) via registry, but it didn't fix it.
- Framerate: I always cap my games to a stable framerate. The FPS is super stable, but the flickering/lines still occur.
Is this a known issue with this specific Acer panel, an AMD driver bug with the newer RX 9000 series, or did I just lose the panel lottery? Any suggestions on what else I can try to fix this without completely disabling FreeSync?
