High Dynamic Range, explained: There’s a reason to finally get a new TV

If you transmit video (on disc, game, or streaming service) via the current, industry-wide HDTV standard, you’re capped at a luminance maximum of around 100 nits. Your screen may be brighter than that, but this is where the current standard really stinks. In that case, the signal sends its luminance information as a percentage, not a pure luminance value. It’s up to your set to translate that percentage, and the results can look, quite frankly, pretty awful. This is how viewers get blown-out colors and other glaring inaccuracies. New HDR standards not only jack a pixel’s luminance maximum up but also change the encoded value to a specific number, not a percentage. That’s the first step to higher color quality on your fancy TV screen. – Sam Machkovech, Ars Technica http://ift.tt/2g2BD0H
