Or, rather, its contrast is completely stunning: alongside that high peak brightness level, HDR tellies will offer incredibly deep blacks. The two side-by-side? A match made in contrast heaven. Black levels are, like brightness, measured in nits, but, here, the lower the figure the better and HDR TVs can go truly low. Think blacks that pull you in deeper than an Interstellar hole. Better still, those deep blacks will be displayed directly next to the ultra-bright highlights, meaning contrast that's out of this world.
