I bought this monitor recently and have been wracking my head trying to figure out this problem. I actually changed graphics card mid-way through this process, both exhibiting the same issue, those being an Nvidia Geforce RTX 4070 and a 5070Ti. This monitor reports itself as Gsync Compatible so I was expecting a frictionless experience however going through settings, games and apps that are affected by VRR trying different things like:
setting framerate limiters on/off
adjusting the refresh rate in windows (120/144)
applying gsync settings such as 'highest refresh-rate available' and 'fixed refresh rate' in the Nvidia Control panel (the latter of which is actually supposed to disable gsync in the described app but it doesnt seem to work)
testing older and latest display drivers, fresh installs
different Display Port cables and HDMI cables, 1.4 and 2.1 respectively.
It seems to be fairly universal, if there is a large swing in refreshrate and it dips down past 48hz, it will occasionally stutter, it is also accompanied by brightness flicker. I have had other Gsync Compatible IPS panels before this that also supported LFC but did not exhibit these artifacts. It is particularly evident in Blender when the software will effectively stop sending frames out and the monitor responds with setting the display to the lowest Hz it can do, then as soon as the model is rotated it goes back to 144. This is where it occurs most, and it is highly distracting when working.
The only way to avoid the frame-skipping and the flicker is turning Gsync off completely which defeats the purpose of using this monitor for games, the thing it's advertised as for.
The displayed Adaptive-Sync menu items on the monitor may vary, depending on the monitor model and compatibility with the NVIDIA graphics card. ● Off: Disable Adaptive-Sync. ● On: Turn on the NVIDIA graphics cards’ Adaptive-Sync function. You may experience intermittent flickers when playing some games.
Apply the optimum resolution when using Adaptive-Sync.
If you use the Adaptive-Sync function while playing a game, the following symptoms may occur: ● The screen may flicker depending on the type of graphics card, the game option settings, or the video being played.
Try the following actions: decrease the game setting values, change the current Adaptive-Sync mode to Off, or visit the NVIDIA website to check your graphics driver’s version and update it with the latest one. ● While you are using the Adaptive-Sync function, the screen may flicker due to variation of the output frequency from the graphics card. ● The response rate during the game may fluctuate depending on the resolution. A higher resolution generally decreases the response rate. ● The sound quality of the monitor may be degraded. " If you encounter any issues when using the function, contact the Samsung Service Center. " If you change the screen resolution while the function is On, the screen may intermittently blank out due to the graphic card. Set Adaptive-Sync to Off and change the resolution.
Supported Resolutions for FreeSync/Adaptive-Sync (VRR) Check the supported resolutions for the FreeSync/Adaptive-Sync (VRR) signal. When Game Mode is set to On or Auto, the FreeSync/Adaptive-Sync (VRR) function is activated. " FreeSync/Adaptive-Sync (VRR) is only available in select models.
