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
