Dell G16 Gaming Screen Flickering 165Hz Windows 11: Nvidia Driver and VRR Fix

Dell G16 gaming laptop features a 165Hz display designed for smooth, tear-free gaming. When the screen starts flickering — horizontal lines, brightness pulses, or full-screen flickers — at 165Hz in Windows 11, the gaming experience becomes uncomfortable and distracting. Dropping to 60Hz often stops the flickering temporarily, confirming the high refresh rate is involved. I have resolved screen flickering on Dell G16 units and this guide explains the causes and fixes specific to the 165Hz display configuration.

Why Dell G16 Gaming Screen Flickers at 165Hz on Windows 11

Nvidia Driver Version Incompatible with G16 165Hz Panel

Dell G16 165Hz display uses an eDP (embedded DisplayPort) interface with specific timing parameters for the high refresh rate. Some Nvidia driver versions have timing compatibility issues with certain panel IDs used in the G16 manufacturing runs. The screen appears stable at 60Hz or 120Hz but shows horizontal flickering artifacts or periodic brightness pulses specifically at 165Hz because the timing values in the problematic driver version do not match what the specific panel requires.

Windows 11 Variable Refresh Rate Conflicting with Fixed 165Hz

Windows 11 enables Variable Refresh Rate (VRR) by default on compatible displays. When VRR is active simultaneously with a fixed 165Hz refresh rate setting, some panel controllers receive conflicting timing signals — the VRR range starts at 48Hz and the fixed 165Hz target can cause the controller to oscillate between states. This manifests as periodic flickering especially during transitions between different frame rates in games or when the desktop renders at a different rate than the game.

Dell Display Manager or BIOS Panel Self-Refresh Causing Conflict

Dell G16 BIOS and some Dell driver packages include a Panel Self-Refresh (PSR) feature that reduces power consumption when screen content is static. On certain G16 configurations, PSR timing at 165Hz conflicts with the panel’s native refresh behavior, causing flickering when the panel transitions between PSR-active and PSR-inactive states. This flickering is often periodic — every few seconds — rather than continuous, and correlates with moments when the screen content changes after being static.

How to Fix Dell G16 Screen Flickering at 165Hz Windows 11

Step 1 — Disable Variable Refresh Rate in Windows 11 Display Settings

Open Settings and go to System, Display. Click Advanced display. Under Choose a refresh rate, ensure 165 Hz is selected. Also look for Variable refresh rate — turn it off. If the option is not visible in Settings, open the Nvidia Control Panel. Go to Display, Set up G-Sync. Uncheck Enable G-Sync. Apply changes. If flickering reduces after disabling VRR, the conflict between variable and fixed rate timing was the cause. Re-enable VRR only if the panel and driver support it without conflict.

Step 2 — Roll Back or Update Nvidia Display Driver

If the flickering began after a specific Nvidia driver update, rolling back to the previous version often resolves it. Open Device Manager, expand Display adapters, right-click the Nvidia GPU and select Properties, go to the Driver tab, and click Roll Back Driver if the option is available. If roll back is not available, visit Nvidia’s website and download a driver version from two to three releases before the current one. Use DDU in Safe Mode to cleanly remove the current driver before installing the older version. After installing, test 165Hz for at least 30 minutes to confirm the flicker is resolved.

Step 3 — Disable Panel Self-Refresh in Nvidia Control Panel

Open Nvidia Control Panel from the Start menu. Go to Display, Change resolution. Ensure 165Hz is selected. Then go to Manage 3D Settings and look for the global setting for Low Latency Mode and set it to Off. Also open Nvidia Control Panel’s Display section and look for any PSR or Panel Self-Refresh option — this may be in the Adjust desktop color settings area on some driver versions. Disable it and apply. Restart the laptop to ensure the setting takes full effect before testing the display at 165Hz.

The flickering on my G16 was driving me crazy. Disabling G-Sync in the Nvidia Control Panel stopped the flickering completely at 165Hz. Games still run smoothly without G-Sync. When I enabled G-Sync again after updating to a newer Nvidia driver version, the flickering did not come back. — Felix D., Dell G-Series Community

Frequently Asked Questions

Is it safe to run Dell G16 at 165Hz continuously?

Yes. Dell G16’s 165Hz display is designed and rated for continuous 165Hz operation. Running at the rated refresh rate does not reduce the panel’s lifespan compared to lower refresh rates. The panel manufacturer tests the display for thousands of hours at maximum rated frequency as part of the certification process. If flicker occurs at 165Hz due to driver issues, the solution is to fix the driver compatibility — not to run at a lower refresh rate as a permanent workaround.

Does Dell G16 support G-Sync with 165Hz?

Dell G16 supports Nvidia G-Sync Compatible mode, which is a VESA Adaptive-Sync certification rather than full hardware G-Sync. G-Sync Compatible allows VRR to operate between the panel’s supported VRR range — typically 48 to 165Hz. For G-Sync to work correctly the Nvidia driver must be compatible with the specific panel variant installed. If G-Sync causes flickering, disable it in Nvidia Control Panel and test at a fixed 165Hz as a diagnostic step.

Why does Dell G16 screen flicker only in specific games but not others?

Game-specific flickering at 165Hz usually indicates the game’s frame rate is falling at or near a problematic frequency for the panel or driver timing. Games that consistently render at frame rates near 165 fps are more likely to trigger timing conflicts with VRR than games rendering at 60 to 80 fps. Limiting the frame rate in-game to 144 fps or 160 fps using Nvidia Inspector or the game’s frame rate limit setting can resolve game-specific flickering without disabling 165Hz entirely.

Does the Dell G16 165Hz screen support HDR?

Check your specific G16 configuration. Some Dell G16 models include an HDR-capable panel while others use a standard SDR display at 165Hz. In Windows 11 Display Settings, if an HDR toggle appears under the display settings for your G16, the panel supports HDR. Enabling HDR can sometimes interact with refresh rate settings — if HDR causes flickering at 165Hz, keep HDR disabled for gaming and enable it only for HDR video content at 60Hz.

Conclusion

Dell G16 gaming screen flickering at 165Hz on Windows 11 is caused by Nvidia driver timing incompatibility with the specific panel variant, Variable Refresh Rate conflicting with the fixed 165Hz setting, or Panel Self-Refresh causing periodic screen flicker during idle transitions. Disable VRR and G-Sync in Nvidia Control Panel as a first diagnostic step, roll back or update the Nvidia driver to a version known to be stable with the G16 panel, and disable Panel Self-Refresh settings if periodic rather than continuous flickering is observed. A stable 165Hz display confirms the driver and panel timing are correctly aligned.
