The projected HDR content depends on the following factors:
• Mastering luminance: This is content-specific and cannot be changed.
• Screen luminance: Every projection screen has a specific luminance (measured in nits or foot-Lambert).
Entering this luminance in the projector will adapt the content towards the intended HDR result.
• HDR Boost: A variable “booster” that may amplify or downplay the HDR output.
How to set the HDR-related parameters?
1. Make sure the chosen Gamma Type is set to AUTO. For more info, refer to “Setting the desired Gamma
type”, page 72.
2. In the main menu, select Image → Advanced → HDR.

3. Select the desired Screen luminance unit (nits or foot-Lambert).
4. Enter the Screen luminance (which is measured in nits or foot-Lambert).
5. Alter the HDR boost if necessary. You can modify this value to somewhere between 0.8 and 1.2.
7.12 Dynamic contrast
About dynamic contrast
Projectors rely on contrast to showcase dark scenes or black parts on the projected surface. Whites and light
areas are usually projected without issue, but blacks and dark areas are a different matter. With low contrast,
blacks and dark areas appear more grey. The dynamic contrast menu is here to improve the dark scene
accuracy.
Dynamic contrast checks the projected content dynamically and adapts the power of the light source
accordingly to create the best possible outcome.
Take note that dynamic contrast isn’t magic. Adapting the light source to adapt its contrast according
to the played content will have an impact on the total light output of the projector. If you do not care
about this feature and want your projector to display the brightest possible content instead, you can
turn this feature off.
