| [#31] Sony UBP-X800M2 4K UHD Blu-Ray Disc Player #14, HDR optimizer Another issue is that HDR10 programs contain metadata that’s supposed to inform the display about the program’s characteristics. More often than not, this data is largely inadequate (or missing, or wrong), so the tone map is generated based on incomplete or misleading information. This is the primary cause of viewer complaints about HDR images looking too dark or displaying clipping in highlights. To combat these common HDR tone mapping issues, Panasonic leveraged what it learned from developing its own flat-panel displays to create a feature that it calls “HDR Optimizer.” When enabled, this feature lets you pick from an assortment of brightness presets that match your display’s capability. Presets include 1500 nits, 1000 nits, and 500 nits, which roughly align with the light output capability of high brightness LCD TVs, OLED TVs, and lower brightness projectors. Once configured, the player applies a tone map designed to match the typical brightness seen from these designs. But the UB820 doesn’t just provide a simple tone map; it also looks at the HDR metadata in the program and bases its processing on that information (including the maximum brightness of the display used for mastering and the program’s maximum pixel level).
