Brightness: round 1000-nits peak brightness in a small 2 to 10% portion of the display and 400-600-nits normal viewing.
Contrast: At least FALD (full array native dimming 500+nits, 5000:1 distinction) LED/LCD or mini-LED (500nits to 1000nits peak, 200,000:1). Only OLED presents round 1000+nits peak and infinite ∞:1 distinction – which means the blackest blacks and whitest whites – the upper the distinction, the higher. The newest LG G3 OLED Evo has 1500nits peak brightness, and DV content material seems spectacular.
Colour Gamut: At least 99% of the DCI-P3 color house with a 10-bit/1.07 billion colors.
Sound: DV additionally comes with a Dolby Atmos (DA) soundtrack*
Dolby Vision films will play on any TV as it’s backwards (downmix) appropriate with HDR10, HDR and SDR – it simply received’t look practically nearly as good.
Currently, the OLEDs from LG and Sony and mini-LEDs from LG, Sony, Panasonic, Philips, TCL, and Hisense help DV and DA. Samsung doesn’t help DV downscales it to the vastly inferior HDR10.
Regardless of the generic TV makers’ declare, edge-lit and direct-lit LED/LCD TVs can not precisely reproduce DV content material.

Depending on the variety of audio system, the impact will increase the 2D Left/Right sound stage to incorporate 3D peak and encompass sound.

At a minimal, DA wants 5.1.2 channels/audio system
Left/Right/Centre entrance (3.X.X).
Left/Right (entrance or rear) side-firing encompass (2.X.X).
A sub-woofer (X.1.X) since you wish to each hear and really feel the bass.
Front up-firing left and proper (X.X.2).

Front Left/Right side-firing encompass (2.X.X)
Rear Left/Right side-firing (2.X.X)
