VRR
Variable Refresh Rate, a technology that synchronizes a display's refresh rate with the GPU's output frame rate, eliminating screen tearing and stuttering. It is an important feature of gaming monitors and televisions.
Timeline (last 90 days)
LFC (Low Framerate Compensation) maintains the equivalent refresh rate within the VRR window by repeating each frame multiple times.
The Switch 2's 23.0.0 firmware update added VRR support in docked mode (TV mode).
LCD panels may exhibit brightness flickering at low refresh rate ranges in VRR mode, and the industry commonly employs LFC technology to keep the refresh rate within an acceptable range through frame doubling.
LFC (Low Framerate Compensation) maintains the equivalent refresh rate within the VRR window by repeating each frame multiple times when the frame rate drops below the VRR lower limit.
VRR is a technology that dynamically matches the display's refresh rate to the game's real-time frame rate, resolving screen tearing and stuttering issues.
The PS5 launched in 2020 without VRR support, and it was not added until April 2022 via a system update.
The Xbox Series X/S launched with VRR support, while Dolby Vision gaming mode was added in a later update.
Nintendo added VRR support for the Switch 2 in docked mode (TV mode) via the 23.0.0 firmware update.
If the TV does not support VRR, the Switch 2 will still output video normally in fixed refresh rate mode.
Implementing VRR in handheld mode requires the display panel, display controller (TCON), and GPU driver to coordinate a synchronized link scheduling pipeline within the SoC, which is more complex than HDMI protocol negotiation.
