7.5.7 HDR
HDR is short for high dynamic range. The HDR function of the MCTRL4K works with
the A8s or A10s Plus receiving card to greatly enhance the image quality of the
screen, presenting more clear and vivid images.
The HDR supports HDR10 and HLG standards. You can use the following two
methods to enable HDR function and set its parameters.
Method 1: Operation on LCD Menu
Step 1 Choose Advanced Settings > HDR and enable HDR function.
Step 2 Select an HDR type from HDR10 and HLG.

When the input source is HDR10, you can set Screen Peak Luma, Ambient
Light and Low Grayscale Mode to adjust the display effect.

When the input source is HLG, you can select one HLG mode from the 7 modes,
namely HLG1 (300 nits) to HLG7 (1700 nits).
