Do G-SYNC Compatible displays work on both DisplayPort and HDMI with GeForce GPUs?

NVIDIA GeForce GTX 10 series (Pascal) and higher GPUs supports VESA Adaptive-Sync variable refresh rate over the DisplayPort 1.2a standard. If you have a G-SYNC Compatible monitor, VRR features will be enabled automatically giving you an improved experience in games. If your monitor isn’t listed, you can enable the tech manually from the NVIDIA Control Panel. It may work, it may work partly, or it may not work at all. To give it a try:

1. 1. Connect the monitor to your GeForce RTX 20-Series or GeForce GTX 10-Series graphics card using a DisplayPort cable

2. 2. Enable the Variable Refresh Rate functionality of your display by using the monitor's controls and On-Screen Display

3. 3. Open the NVIDIA Control Panel from the bottom right of Windows

4. 4. Expand the "Display" section

5. 5. Click on “Set up G-SYNC”

6. 6. Tick the “Enable G-SYNC, G-SYNC Compatible” box

7. 7. Tick the “Enable settings for the selected display model” box

8. 8. Click “Apply” on the bottom right

9. 9. If the above isn't available, or isn't working, you may need to go to "Manage 3D Settings", click the "Global" tab, scroll down to "Monitor Technology", select "G-SYNC Compatible" in the drop down, and then click "Apply"

10. 10. Additionally, you may need to go to "Change Resolution" on the left nav and apply a higher refresh rate, or different resolution

NVIDA GeForce GTX 16 series/RTX 20 series (Turing) and higher will support variable refresh rate over HDMI on displays which support this feature over HDMI 2.1. For the best gaming experience, we recommend a G-SYNC Compatible display. To enable this:

1. 1. Connect your TV via HDMI to your GeForce RTX or GeForce GTX 16-Series or higher GPU

2. 2. Enable the HDMI 2.1 Variable Refresh Rate functionality of your TV/display through it's own internal settings

3. 3. Open the NVIDIA Control Panel by right clicking your desktop > NVIDIA Control Panel

4. 4. On the left nav, select Display > Set up G-SYNC

5. 5. Enable G-SYNC, and click Apply on the bottom right of the window

If you don’t own a G-SYNC Compatible TV, but do own a display or TV that only supports variable refresh rates via HDMI 2.1, you can try enabling G-SYNC as detailed above. As these displays and TVs have yet to through our comprehensive validation process, we can’t guarantee variable refresh rates will work, or work without issues.
