Function
HDR
The projector supports HDR imaging sources. It can
automatically detect the dynamic range of the source from
HDMI 1, and optimize settings to reproduce contents under
wide range of light conditions. If the input source is not
defined with dynamic range, you can also manually select
Auto or SDR for it. Adjusting the setting will have no impact
if the projector receives a non-HDR content.
HDR
EOTF
The projector can automatically adjust the brightness levels of
your image according to the input source. You can also
manually select a brightness level to display better picture
quality. When the value is higher, the image becomes brighter;
when the value is lower, the image becomes darker. This
function is not available when SDR is selected in the HDR
menu.
