JVC has officially unveiled all the details on the update that improves the operation of HDR projectors and facilitates their adjustment. Firmware 3.50 will arrive in November 2020 on DLA-N5, DLA-N7, DLA-NX9 models and on counterparts distributed through professional channels, namely DLA-RS1000, DLA-RS2000 and DLA-RS3000. The first change is related to the Frame Adapt HDR function, introduced last year to optimize the performance of HDR10 videos through dynamic tone mapping.
Projectors analyze images in real time, acting frame by frame or scene by scene. This way you get information about the brightness and colors present in the contents to be shown on the screen. These data, in particular the peak brightness, are then used to adapt the dynamic range of the videos in real time to that actually available on the projectors, improving image quality.
The novelty that will arrive in November consists in a refinement of the Frame Adapt HDR and in particular in the addition of the Theater Optimizer function, designed to intervene with more precision on HDR content according to each specific installation. Theater Optimizer allows the user to enter a lot of information about their system. It speaks for the accuracy of the screen characteristics in terms of size and gain (how much light is reflected towards the viewer), the zoom position on the projector, the condition of the lamp and its settings.
The data entered allows the projectors to automatically adjust to optimize the performance of dynamic tone mapping by tailoring it to each system consisting of projector, screen and environment. It is therefore a device that allows you to apply the Frame Adapt HDR with even greater precision and taking into account many parameters that can also change over time.
The consumption of the lamp, for example, progressively changes its performance and would therefore require manual intervention with adjustments made periodically. With this feature, JVC has automated the process. Frame Adapt HDR can also be adjusted to five levels instead of the previous three, thus expanding the options available to users.
Below is the complete list of upcoming news:
- The brightness settings have been increased to five levels for the Frame Adapt HDR feature (compared to the previous three levels).
- New Content Type menu, showing usable picture mode based on each input signal. Since only the picture mode corresponding to the input signal can be selected, problems due to display of incorrect gamma or color spaces are eliminated. There is a function that automatically activates the optimal color profile based on the color space of the contents.
- The new Auto Pic feature. Mode Select performs mode transitions in response to different input signals (SDR / 3D / HDR10 / HLG).
- Picture mode for Panasonic's DP-UB9000 Ultra HD Blu-ray Disc Player. A picture mode has been added that allows for simple and optimized connection without the need for specific manual adjustments.
- Improvements to JVC calibration software.
The firmware can be downloaded for free from this page as soon as it is available. Once the update has been performed, it will no longer be possible to return to the previous version and all settings will be restored to factory default values.
