4K Blu-ray vs Blu-ray Reveals HDR Is Too Dim for Daytime
We were experimenting with introducing ambient lighting to see if we could better mask the backlight inconsistencies and local dimming issues in HDR mode on the LED LCD televisions we were testing, but invariably found ourselves asking, “Why does the HDR picture look so unimpressive? We can’t make out any dark detail!”
Here’s the rub: because [Backlight] and [Contrast] are already maxed out on HDR televisions during the playback of 4K Ultra HD Blu-rays, there’s no straightforward way to increase the display’s light output during the day to avoid the picture being drowned out by competing ambient light – a good analogy is how you need to boost your smartphone’s screen brightness under the sun for the text to remain readable. Even with only a moderate amount of ambient light in our test room, dark HDR scenes (such as the dust storm sequence in The Martian) became extremely difficult to watch – our constricted pupils just weren’t able to discern sufficient shadow detail in the presence of room light.
Let’s recap the problem in a nutshell: the HDR presentation in current Ultra HD Blu-ray films is not bright enough for viewing under moderate/ strong ambient lighting, because the HDR metadata forces compatible TVs to be driven at their maximum backlight capacity, leaving no room for higher light output. Of course, there exist other avenues (such as gamma adjustment or dynamic contrast trickery) to brighten the on-screen image for daytime viewing, but these are generally insubstantial compared with the most effective method of raising backlight luminance.
Insisto, no se trata de ir "en contra", sino revelar TODO lo concerniente, bueno y malo. Esta página WEB de hecho es MUY CRITICA al respecto y ponen a los OLED incluso a cuenca. Aquí revelan que salvo que veas material HDR a OSCURAS, con apenas añadir luz ambiental se va al carajo el "efecto HDR".
Algo que, curiosamente, sucede igual con los OLED, donde dan todo su do de pecho a oscuras (a plena luz día el negro de un LCD y de un OLED es "el mismo").
Si nos quedamos solo con lo bueno y desechamos lo malo, estamos haciendo flaco favor a los más indecisos. Las cosas hay que contarlas de principio a fín.
