JVC will firmware upgrade its 4 and 8k e-shift projectors with a new Theater Optimizer smart function, able to intelligently adjust tone mapping according to the screen it’s partnered with, this November.

The installer, or user, enters screen size and gain information, and the Theater Optimizer adjusts a range of internal projector settings to optimise HDR performance accordingly.

Frame Adapt HDR with Theater Optimizer will be available as a free firmware upgrade from November 2020, for its DLA-N5, DLA-N7, DLA-NX9, DLA-RS1000, DLA-RS2000 and DLA-RS3000 models.

JVC originally introduced Frame Adapt HDR in October 2019, adding dynamic tone mapping to their 4K and 8K e-shift models. With this new update, 4K HDR10 streaming, games and Blu-ray content will be automatically adjusted for optimised brightness, colour and detail, on a frame by frame or scene by scene basis.

Based on a proprietary algorithm, Frame Adapt HDR analyses the peak brightness of HDR10 content (including Dolby Vision titles) and adjusts the optimal dynamic range in real time.

Theater Optimizer allows the installer or user to input the screen size and gain information, which tends to vary depending on the theater design, and then calculates installation information such as lens zoom position, and lamp condition and settings. It then automatically adjusts the projector for optimum tone mapping and brightness. By adding this function to Frame Adapt HDR, JVC says this allows users to enjoy HDR10 content matched to the viewing environment without complicated manual adjustments.

18-bit level gamma processing is maintained while the feature is in use, bringing out deeper blacks in darker scenes, and higher peak whites in brighter scenes.

In response to user requests, Frame Adapt HDR brightness adjustment has been increased to five steps (previously three steps), and users can choose the picture mode according to input signals. Complicated individual manual settings that were required in the past are now eliminated, it says. 

Also new is a dedicated picture mode for Panasonic's DP-UB9000 Ultra HD Blu-ray player.
