Brightness: Adjust the brightness from 0 to 100. Note: Adjusts the balance between light and dark shades. 2. Contrast: adjust the contrast from 0 to 100. Note: Sets the degree of difference between light and dark areas. 3. Low Blue Light: Filter out blue light to protect your eyes by adjusting how much blue light is shown --Level 1, 2, 3, 4. Note: A lower level allows more blue light to pass through, so in order to achieve the best protection, please select a higher level, of which Level 4 is in the best state. 4. Black Boost: This boosts the amplitude of the dark color levels of the display- blacks will be less black. The higher the level, the higher the boost. 5. ACM: Turn ACM on or off. The default is off. 6. HDR: Turn HDR Off, Auto or HDR. The default is Off. Select Auto enables this function to automatically detect and process HDR signal. Note: 1. If HDR is "Auto", then Modes is set to "HDR" automatically. 2.

HDR function is only available for HDMI 2.0. or DP. 7. Super Sharpness technology can simulate high-resolution images by boosting the pixel density of the original source.
