JVC 4K D-ILA Firmware Update Enhances HDR10
JVC announced Thursday a new firmware update for its native 4K D-ILA projectors that will bring enhanced frame-by-frame analysis and adjustment to HDR10 profile high dynamic range content.
JVC will demonstrate the new HDR capabilities next week at CEDIA Expo in Denver, CO.
The company said the new “Frame Adapt HDR” system delivered in the update is designed to automatically optimize brightness and color on a frame-by-frame basis from the static metadata HDR10 source profile.
JVC said the firmware update will be available for download at no charge in October for the JVC native 4K D-ILA projector models: DLA-NX9, DLA-NX7 and DLA-NX5 as well as the Reference Series DLA-RS3000, DLA-RS2000 and DLA-RS1000.

The company explained that “because content brightness varies, a fixed setting cannot deliver optimum image quality. JVC’s new Frame Adapt HDR solves this by instantly analyzing the peak brightness of each frame or scene using a proprietary JVC algorithm, and adjusting dynamic range to provide the best possible HDR image. Frame Adapt HDR works with any HDR10 content, even content that does not contain brightness metadata (Max CLL/Max FALL).”
Main features in the update include the following:
- Adjusting dynamic range in real time for optimal image projection, while simultaneously analyzing saturation, hue to make optimal corrections and reduce color loss. Even with a single program, JVC said darker scenes have deeper blacks with enhanced color. Bright scenes have higher peak brightness without color loss while maintaining black level. All content is reproduced closer to what the human eye is capable of seeing.
- Compatiblity with all HDR10 content enables Frame Adapt HDR adjustments based on analysis of the input HDR10 signal, and is therefore effective on content with or without mastering information. “As a result, all HDR10 content can be enjoyed with greater dynamic range and image quality,” the company said.
- Gamma processing accuracy, which in the past was based on 12-bit equivalent, has been improved to 18-bit and as a result gradation performance is dramatically improved. JVC said that in any given scene, this reduces the banding effect in the bright portions and the crushing of dark portions. As a result images are more accurate, offer smoother gradation along with higher average peak level brightness and increased color saturation.
Other Improvements include: support for 16:9 aspect ratio content when using a Panamorph Paladin DCR lens (adds Anamorphic D). JVC said it is now possible to leave a Paladin DCR lens in position and view both ultra-wide and 16:9 content correctly.
The update also brings Auto Calibration support using the Spyder X sensor and adds new presets to the screen adjustment function.
