Valve was using HDR on half life the lost coast. This isn't something new. I'm guessing this is where dolby got the idea from.

I run my backlight at three on my 2009 CCFL back lit Samsung, Modern LED tvs are way too bright imo. So why does Dolby think we need tvs that are brighter?

HDR is annoying in some games though. Fall out 3 for instance crushes blacks, Far Cry 2 was even worse. The COD games use HDR very well, and Dead Island looked absolutely incredible with it on.

Interesting. The idea of "f stops" versus "dynamic range" (ie, more resolution between the same end points, not just two end-points farther apart) is similar to how I've theorized about bit-depth for digital audio. I've often thought that 24 bit audio sounded "more real" than 16 bit audio even with source material that didn't seem to have enough dynamic range to need the added bits. But the idea was that even within the same range, the gradation of amplitudes was finer and did a better job convincing the ear that the sound was "real".

1080p and lossless audio. EVERY BD should have them both.

Yeah, they simulate it by changing the exposure of the virtual camera. I guess bumping it up to 10-12bits per color channel wouldn't hit memory bandwidth that hard since games can already use up to 64bits per pixel (only 24 of those bits are color).

I still don't think they'd bother with higher bit depths until the displays had real traction in the market and people cared enough to demand it. There's millions of 3DTVs out there now, but if anything less and less games are supporting it over the past few years.

Dolby will be showing this display at 2014 CES (via appointment only). Can't wait to see the finished product (as opposed to the early prototype I saw half a decade ago)! smile.gif

I'm sure Ray Dolby must be smiling in heaven.....most bluray movies if not calibrated right can look too dark or too bright than a cinema screen.
