Why does the video displayed on TV lack of color?

Please make sure the “HDR” function is set to “OFF” and adjust the “color space” of the source device to “4:4:4” or “4:2:0”, that will help.

As we know, Sony A7III, Sony A6400, Sony A6500 or certain device’s “color space” settings are fixed at “4:2:2”. You have to adjust the camera/device’s resolution to 1080p to use it. Please do understand that this is not a product quality issue.
