For better performance and to keep up with the high refresh rate of Holoscan applications, we recommend the use of a G-SYNC display.

Holoscan has been tested with these two G-SYNC displays:

  • Asus ROG Swift PG279QM
  • Asus ROG Swift 360 Hz PG259QNR

Follow these steps to ensure G-SYNC is enabled on your display:

  1. Open the “NVIDIA Settings” Graphics application (nvidia-settings in Terminal).

  2. Click on X Server Display Configuration then the Advanced button. This will show the Allow G-SYNC on monitor not validated as G-SYNC compatible option. Enable the option and click Apply:

    Enable G-SYNC for the current display
    Enable G-SYNC for the current display

  3. To show the refresh rate and G-SYNC label on the display window, click on OpenGL Settings for the selected display. Now click Allow G-SYNC/G-SYNC Compatible and Enable G-SYNC/G-SYNC Compatible Visual Indicator options, then click Quit. This step is shown in the image below. The Gsync indicator is at the top right of the screen once the application is running.
