It appears the display shows intermittent flickering or blinking when G-sync is activated.
Hello there! I’m glad you’re excited about your new monitor. I wanted to share my experience with the G-sync feature. My setup is an Asus VG27AQ TuF gaming model, 2560x1440 WQHD. When I enable G-sync in the NVIDIA control panel, my screen occasionally flashes three times, almost as if it’s adjusting itself. This happens every time I switch contexts—opening a new folder, browser, Steam library, or anything new on my PC. At first I thought it was the monitor reacting to brightness changes, but soon realized it only occurs when G-sync is active. It disappears immediately when I turn it off. Interestingly, the monitor settings menu shows “adaptive-sync: ON (G-sync compatible)” even though the NVIDIA panel lists it as off. This makes me a bit confused. Could you help clarify why it blinks when G-sync is enabled and why it appears in the settings but not in the control panel? I’m not very tech-savvy, so any advice would be greatly appreciated. I’ve been playing 60fps games smoothly since the purchase, but it feels odd to invest in a G-sync monitor if it doesn’t seem to help much.
You need to turn on adaptive sync on your monitor, which you can do in Windows. However, it’s not automatically active there. The flickering you mentioned wasn’t fully resolved—after some time it stopped working. It probably had to do with software settings rather than a hardware problem. I once thought the issue was related to HDR adjustments for different apps.
Your display lacks G-sync functionality but supports Freesync instead. Both technologies operate within Variable Refresh Rate (VRR) systems. To turn VRR on, first enable it on the monitor and then in the control settings. Only when both are active will the option appear. If Freesync is off in the monitor, the panel won't show an activation choice. Avoid referencing windowed or full-screen settings; stick to fullscreen mode only. The intermittent flickering you notice might relate to brightness variations caused by Low Framerate Compensation (LFC). When performance drops below a certain frame rate—typically around 40-50 FPS—the monitor adjusts its refresh rate from perfect sync to double the rate or a higher one. Since refresh rates change dynamically, this rapid shift can create a noticeable brightness fluctuation, which may appear as blinking.
I didn't understand how to describe the blinking issue. It seems to have resolved itself now. I tried turning G-sync on, off, and back again, and it looks good so far. I don't know why it works after that. Also, when I searched for compatible monitors, I only found G-sync enabled. That's why I assumed it was a G-sync display. Regarding Vsync, should it stay ON in 3D settings if G-sync is active? I recall hearing about this. Currently it uses 3D application settings, but I think it should be set to G-sync on and Vsync off during games. Thanks for the advice!
Gsync activated alongside Vsync enabled is the best approach. If Vsync is disabled, you might notice some tearing. Disabling Vsync provides marginally lower latency, but it's not crucial. Setting Vsync to off in the control panel changes game configurations so you don't need to worry about specific settings. Avoid using any other options like "fast" or anything beyond "On", "Off", or "Application setting".
G-sync activated and Vsync enabled in 3D mode. Appreciate the assistance.
