To set up G-SYNC
From the NVIDIA Control Panel navigation tree pane, under Display, click Set up G-SYNC to open the associated page.
If not checked, then click the Enable G-SYNC/G-SYNC Compatible check box.
Select either Full screen mode or Windowed and full screen mode, depending on your system and the programs you plan to run.
Full screen mode: Select this option if your system experiences difficulty using G-SYNC with windowed applications, but you still want to use G-SYNC with full-screen applications.
Windowed and full screen mode: Select this option if you want to use G-SYNC with windowed applications.
Choose a display-specific application of G-SYNC settings.
This step applies to either G-SYNC Compatible displays or VRR displays that have not been validated by NVIDIA as G-SYNC Compatible. After enabling G-SYNC, you can select which connected display models to apply the G-SYNC settings from step 3. This is also useful for testing G-SYNC on VRR displays that are not validated as G-SYNC Compatible.
To apply G-SYNC settings to all connected displays of a particular model,
At Select a display, select the display model icon.
At Choose display specific setting, check the Enable settings for the selected display model check box.
Follow the instructions on the rest of the page to enable G-SYNC.
Make sure you have a G-SYNC-capable or G-SYNC Compatible display connected, enabled, and configured as the primary display.
Make sure Monitor Technology is set to G-SYNC/G-SYNC Compatible from the Manage 3D Settings page.
