9.0  4K INPUTS
9.1  Choosing the correct Input level
Because the Input level of 4K sources are generally “(0-255) Enhanced” input levels, and at the contrary, classic
Blu-Ray discs and HDTV programs use “(16-235) Standard” Input levels. It is important to clearly identify and to
select the correct input level to achieve perfect blacks.
To identify the correct level, you can for example select a dark scene from your movie and switch between
Standard and Enhanced Input levels. The correct Input level would be “Enhanced” if this setting gives the
deepest blacks. If both settings give the same result, then your source uses “Standard” levels.
Generally UHD sources use Enhanced levels: You may try to congure your UHD player to output
Standard levels to be consistent settings with Bluray playback.
Menu => Input Signal => Input level => (0-255) Enhanced
9.2  High Dynamic Range sources
Identifying HDR sources.
HDR sources are almost exclusively from the latest UHD discs or TV/internet streaming video that come with a
HDR logo. If your player supports this format, this unit should automatically detect the HDR format thanks to the
HDMI 2.0 handshake and the projector should apply automatically the correct Color Prole “HDR”. Make sur that
the correct Gamma is selected depending on your source: Hybrid Log, ST.2084 or Standard.
It is important to determine which color prole it uses between REC-709, DCI-P3 and BT-2020. Choosing the
correct gamma and color prole is very important to obtain the best performances from your source and to have
a perfect colorimetry with a greater sense of depth.
Correct Gamma settings
If the source is clearly identied to be using High Dynamic Range, the projector should display “HDR:
YES” in the Menu > Information Menu and the Picture Mode “HDR” should be applied automatically.
If your HDR image seems dull and without depth, check in the Menu > Information and check if the correct Color
Prole has been applied, and that the Colorimetry is HDR. If this is the case, you can also switch the Color Prole
from HDR to BT.2020.
Menu => Picture Mode => HDR10
Menu => Picture Adjust => Color Prole => HDR (slightly brighter than BT.2020) or BT.2020
HDR10 Auto Tone Mapping
Depending of the movie and its director, picture grading varies diversely between each movie. Some content being
made brighter and others darker. Enabling the “Auto Tone Mapping” function, allows the projector to adjust the
HDR gamma automatically by reading and applying the optimal brightness based on the mastering information
(Max CLL/Max FALL) contained in the HDR10 content. You can manually
HDR10 Mapping Level
Mapping Level is an independant adjustment that determines the picture brightness base level. Raise or lower
the Mapping Level to obtain the best overall brightness tting your screen size and material gain. By default the
middle setting (“0”) will be adapted to a screen diagonal of 100” (2m20 wide) and a gain of 1.0. Increase this value
