Sample images Note the brighter hilights, making the whole image more real:
You may not want 4K TV because the resolution is four times higher than HD, HD is plenty for most viewing. But you will want the realistic hilights now possible with 4000 nit brightness. Consider your current HDTV shoots no more than 100 nits at you.
Brightness is the new surprise and offers even finer apparent resolution. Once you see a 4000 NIT 4K TV, you can't go back to a 100 NIT HDTV.
By bumping up that brightness to 4,000 nits, the Dolby Vision prototype display isn’t just brighter, it appears crisper too. Colors look amazing and details that are lost in the mastering process for 100 nit HDTVs reveal themselves.
Dolby's not after brightness for brightness' sake, however. Instead, it wants the highlights to be really bright, while the rest of the image is not, for a greater contrast ratio. Parts of the image might be 20,000 nits, but the rest is dimmer. Even in a dark room, this produces a more realistic image. Bright areas pop in a lifelike way. Dolby's prototype (discussed below) uses a local-dimming LED backlight to create this incredible contrast, but a technology OLED is able to achieve something fairly close on its own.
The eye can handle up to 10,000 nits of brightness, the new Dolby Vision TV offers hilights at 4000 nits making the image better than the Cinema, and almost as bright as reality!
