Variable refresh rate (VRR)
Only on select models:
Variable refresh rate (VRR) allows a compatible game console
or computer connected via HDMI to control the refresh rate of the TV. This feature
helps to ensure that the TV does not begin to display a video frame until the video
source has completely rendered it. The result is smoother image animation with a
lower instance of stutter or tearing. This feature requires the following conditions:
• Variable refresh rate is turned On in the HDMI settings for the input. This
setting is Off by default.
• The HDMI mode is set to Auto or HDMI 2.0 in the HDMI settings for the input.
• Game mode is enabled.
• The connected device supports VRR.
