Screen page contains display related options and software image adjustments.

  • Display Mode
    • Changes the hardware resolution and frequency of the displays inside the headset (be aware that this requires headset restart).
    • Only resolutions predefined in the headset firmware are available.
    • This does not influence the software resolution set in the Quick Settings section or on the Settings – Headset – Rendering page.
  • Brightness
    • Directly changes the brightness of the displays inside the headset.
  • Gamma
    • Can be used to adjust the gamma value of the image displayed inside the headset.
    • This adjustment is applied independently on the end VR application, and only after the final image is rendered.
    • This functionality will not be available if you are using the Somnium SteamVR Driver
  • Contrast
    • Can be used to adjust the contrast value of the image displayed inside the headset.
    • This adjustment is applied independently on the end VR application, and only after the final image is rendered.
    • This functionality will not be available if you are using the Somnium SteamVR Driver
  • Brightness Correction
    • Can be used to adjust the brightness value of the image displayed inside the headset.
    • This adjustment is applied independently on the end VR application, and only after the final image is rendered.
    • This does not influence the hardware brightness of the displays set with the Brightness slider above.
    • This functionality will not be available if you are using the Somnium SteamVR Driver
  • Reset to Default Values
    • Allows resetting Gamma, Contrast, and Brightness Correction to their default values.
  • Local Dimming
    • Can be used to enable/disable local dimming functionality.
    • Several local dimming modes can be selected based on user preference or specific application.
      • Linear mode uses a basic averaging algorithm which behaves the same for darker or lighter areas.
      • Dynamic mode is designed to achieve the best contrast between darker and lighter areas.
      • Natural mode uses a custom averaging algorithm to more closely resemble how human eyes adjust to light changes, but it may cause more artifacts.
      • Medium mode uses a linear averaging for the darker areas and more natural averaging for the lighter areas.
    • Minimum black level can be adjusted – lower values will mean darker blacks, but more artifacts may occur in areas with high contrast.
