Check for fluctuations without G-Sync settings active.
I own a GSync display and another monitor not tied to GSync. With the second monitor connected via integrated graphics, my main GSync worked perfectly. Recently I turned off the iGPU and connected both monitors to my NVIDIA graphics card, but now the main GSync monitor flickers after using GSync. The issue appears to happen when opening and closing games, with a sporadic pattern of flickering every few minutes. Restarting the PC and not using GSync stops the problem, but plugging in the second monitor again resolves it. If I turn off GSync entirely, the flickering disappears as well. Removing the second monitor also eliminates the issue. My system runs Windows 11 22H2 on an x64 ASUS Prime z590-A with an Intel i7-10700k, 32GB DDR4 RAM, and an EVGA 3070ti PSU (750W). The GSync monitor is a Dell 2422HS. It seems some users faced similar problems, possibly due to driver issues on NVIDIA hardware, which didn't have a clear fix. Could anyone share experiences or solutions? My friend who upgraded his monitor before me also had flickering issues, eventually switching to a different model after encountering dead pixels.
I've experienced similar problems with Windows 11 across all versions, though I'm assuming Windows 10 would face the same challenges. Updates from Microsoft have helped improve stability, and keeping the Nvidia drivers current makes a difference. Sometimes forcing HDR toggling or adjusting settings resolves the flickering, and a restart can help. If you're missing the latest drivers or Windows isn't fully updated, that's likely the cause. Also, setting G-Sync to full screen mode instead of windowed can worsen the issue.
It's typical for Nvidia G-Sync and AMD Free-Sync to cause occasional flickering. This occurs when the frame rate drops below their synchronization limits. To avoid flicker, you can disable G-Sync or adjust settings so it activates automatically when launching a game.
Frequently pressing Alt + Tab in and out of full-screen games works fine. It might help to experiment, as behavior can vary by game. A driver update seems unlikely to solve this—it appears to be an OS issue, since the DWM must handle G-Sync everywhere. Nvidia’s Enable setting for full-screen mode is likely the default, but current Windows 11 VRR support isn’t fully aligned. The article you read highlights many requirements for games to function properly, especially with full GPU power and features like HDR, G-Sync, and overlays. For optimal performance, true full-screen is recommended.
