Hi Frank Logrim, thanks for the details. First, confirm your monitor supports VRR over the connection type you’re using many models only support VRR via DisplayPort, not HDMI, so try a DisplayPort cable if possible. Second, in Windows go to Settings > System > Display > Graphics > Default settings and make sure Variable Refresh Rate is enabled. Third, in NVIDIA Control Panel, check Set up G-SYNC and enable it for your monitor; if it’s not listed as G-SYNC compatible, enable settings for the selected display model. Fourth, update your GPU drivers or use DDU to reinstall them cleanly. Fifth, check your monitor’s on-screen settings to ensure VRR or Adaptive Sync is turned on. Sixth, note that HDMI VRR requires HDMI 2.1 and a compatible cable; if your monitor only supports VRR via DisplayPort, HDMI won’t work. If none of these steps help, it may be a limitation of the monitor or a bug in the current Windows build, so check for updates or try rolling back to a previous driver.
If this helps, please mark the answer as accepted so others can find it too.
