JVC upgrades firmware for DLA-RS4500K

JVC has announced a firmware update (V2.0)  for the top-of-the-line DLA-RS4500K 4K laser projector, adding various functions and features, including auto tone mapping, color profiles for the Panasonic DP-UB9000 Blu-ray player, and a number of screen adjustment modes.

The upgrade will be available on June 27, 2019, and explanations of the key features follow:

Auto Tone Mapping automatically adjusts settings for optimum HDR10 images. The HDR10 mastering information MaxCLL (Maximum Content Light Level) / MaxFALL (Maximum Frame Average Light Level) varies greatly depending on content. To achieve the best HDR10 experience it is necessary to set the appropriate brightness settings for each piece of programming. The Auto Tone Mapping function automatically adjusts settings based on the mastering information. Various HDR images with different brightness can be viewed optimally without manual adjustment of the settings. In cases where content does not contain mastering information, a fixed value will be set or it can be manually adjusted.

Dedicated Color Profiles for the the Panasonic DP-UB9000 UHD Blu-ray Player allow users to select one of two dedicated color profiles developed specifically for the Panasonic 4K UHD player. The projector’s profiles work in conjunction with the player’s HDR Optimizer, which tone maps HDR content based on the metadata to match the capabilities of the projector.

Expanded Screen Adjustment Modes correct the color balance for a wide range of screen characteristics and materials. The firmware upgrade expands the number of screens settings from 135 to 165.

The JVC DLA-RS4500K combines a JVC-developed native 4K D-ILA device with the company’s proprietary BLU-Escent laser phosphor light source. It is rated at 3,000 lumens brightness, making the RS4500 ideal for large screen 4K HDR applications.

  1. They added tone mapping and a special mode optimized for use with the Panasonic player HDR settings. I haven't heard anything on if they will be adding these features to projectors that cost less than $30,000.

    I thought the lower cost RS1000-3000 models already had firmware optimized for the Panasonic players with new color profiles. https://hometheaterreview.com/jvc-and-panasonic-join-forces-to-make-big-screen-hdr-better/

    What I like to know is whether this also applies to the far more affordable Panasonic UB820.
