JVC’s DLA-RS4500K 4K Laser Projector Gets Firmware Update
A V.2.0 firmware update available at the end of June will endow JVC’s flagship 4K laser projector, Model DLA-RS4500K, with new functionality and features. These performance enhancements include Auto Tone Mapping, color profiles for Panasonic’s 4K UHD Blu-ray player, and additional screen adjustment modes.
The Auto Tone Mapping function automatically adjusts settings for optimum HDR10 images. Since HDR10 mastering information MaxCLL (Maximum Content Light Level) / MaxFALL (Maximum Frame Average Light Level) varies depending on content, to achieve the best HDR10 experience, the Auto Tone Mapping function automatically adjusts brightness settings for each piece of programming, based on 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.
For the Panasonic DP-UB9000 UHD Blu-ray player, users can select one of two dedicated color profiles developed specifically for it. 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.
