Dynamic HDR: Ensures that every scene, even every frame, of video displays the ideal values of depth of field, detail, brightness, contrast, and a wider color gamut. 5. Variable Refresh Rate (VRR): Supports 1080P-240Hz/2K-165Hz/4K-144Hz, which can synchronize the refresh rate of the screen and the signal source, which can reduce the delay, jams and tear of the screen. 6.
