What Is The HDMI Black Level Setting?

Last Update Date : May 10. 2019

Black level is defined as the level of brightness at the darkest part of an image or the level of brightness at which no light is emitted from a screen, resulting in a pure black screen.

HDMI Black Settings

In digital video black level usually means the range of RGB values in video signal, which range can be expand from 0~255. When an HDMI device that supports an RGB color range and already use the 0-255 HDMI black level range is connected, the HDMI Black Level option will be grayed out.  


Four options for setting HDMI Black Level: 


Off: Turns the HDMI Black Level enhancement off.

Low: Sets the HDMI Black Level enhancement for low.

Normal: Sets the HDMI Black Level enhancement for medium.

High: Sets the HDMI Black Level enhancement for high. 


If the external device you have connected does not support the full black range that the TVs panel can support you can enable the HDMI Black Level function and have the TV compensate for this lack of black level.
