HDRTVs

HDRTV, or High Dynamic Range Television, refers to televisions capable of displaying a wider range of brightness and color compared to standard High Definition Television (HDTV). This increased dynamic range allows HDR TVs to show brighter highlights and deeper blacks simultaneously, resulting in a more realistic and lifelike image.

The expanded color gamut of HDR TVs also means they can display a broader spectrum of colors, leading to more vibrant and nuanced images. This technology relies on specific HDR formats, such as HDR10, Dolby Vision, and HLG (Hybrid Log-Gamma), each with its own specifications for metadata and signal transmission.

For a viewer to experience HDR content, both the display device (the HDRTV) and the source of the content (e.g., a Blu-ray player, streaming service, or game console) must support HDR technology. Content specifically mastered for HDR is required to take full advantage of the capabilities. When viewing SDR (Standard Dynamic Range) content on an HDR TV, the TV will typically downscale the signal to fit its capabilities, though some TVs offer upscaling features to enhance SDR content. The overall effect of HDR is a more immersive viewing experience with greater detail in both the brightest and darkest areas of the picture.
