Usually 200-250 nits people set to for SDR in bright room.

100 nits is for dark room. And the standard all SDR movies are made in.

I have curtains that block light so I adjust all my displays to 100 nits. Anything higher hurts my eyes. Sun light messes with my TV.

For me 100 nits
It's easier on the eyes in the dark.
Makes TV last longer.
Greatly reduces burn in since most stuff I view is SDR.

In HDR the LG OLED's can only reproduce color up to 350 nits. Then the White Subpixel kicks in at 350 nits and beyond to boost brightness.

Makes these TV's not so good for accurate HDR color reproduction sadly.

Hmm I see. I always use the TV when it's dark in the room by covering the windows, but somehow I still prefer the max pixel brightness. Doesn't seem too bright or even close to being uncomfortable for the eyes for me.

Oh I see, I always assumed the white pixel is what gave the high 750 nits capability for small windows. It still looks great for highlights though.

People prefer a brighter image. It's just what our eyes are attracted to.

For me 120 nits is max I can handle for a pc monitor up close. And 150-180 nits for a TV farther away.

The White pixel does give 750 nits of brightness. But colors can only be reproduced up to 350 nits. Beyond that it leads to desaturation in color.

I think LG tries to incorporate some algorithm to lessen this but idk.

In HDR you'll be seeing alot of scenes at 100 nits. Not eveything is at 1000 nits.

Some scenes will be in the 100 nits range. Some at 300 nits. Or you may have a mix of some parts with 100 nits and like street lights at 1000 nits.

But I think alot of content sits in the 100 nits range in HDR. I need to recheck that though to see how movies are mastered.

Jiehfeng

Yeah definitely a preference thing, I tend to prefer higher brightness, phone always at 60-70%, 3DS I used to choose the max or 4 in dark rooms, and even when it comes to sound I prefer things louder.

Oh yeah definitely, I knew that. HDR scenes most times are low brightness, sometimes lower than SDR a lot as well, the highlights and whatnot is what gets bright yeah. It does give a good contrast for it though.

This video I linked before shows how games are mastered in HDR with a wave form.

It's really good at showing what parts of the scene lie in the SDR 100 nit range and which in the higher HDR range. Most seem to be in the 100 to 500 nit range.

It does lead to people saying that HDR looks dim for many scenes. But it's just how its mastered to really give that dynamic range and pop for certain light sources.

Interesting, I'll give it a watch. Practically though it just seems that whenever there's a bright part of an image especially closer to the whites, it goes higher than the regular brightness. When no such light is present the whole image is darker.

Jiehfeng

Yeah, but hopefully as time goes on and burn in is not an issue anymore, I hope the non bright areas become normal brightness, with the highlights bumped up more. Currently even though it still looks great, doesn't seem accurate like regular scenes where it shouldn't be as dark.

Sunlight is 1.6 billion nits.

So with HDR grading colorist have to approximate that look on 1,000 nit displays. It really depends on how they choose to colorize it.

It's not meant to be like real life but however they choose based on what feels right to them.

Basically artists with a paint brush. And art can vary.

It's like the movie Sin City real life is not black and white with red spots, but colorists choose different color pallets for certain scenes and movies to give certain feels and moods. To convey emotion with color.

TV was never meant to look like real life.

Jiehfeng

Sure, but in media that tries to look as real as possible, scenes being darker than it should be seems a bit off. Not referring to sunlight not being too bright, but something like a scene in a room where it's too dark looks off.

Could be how it was made. Or maybe tv settings?

They could brighten things up if consumers demand it.

But if everthing is bright it could lead to less dynamic range. Like in audio with less dynamic volume range in todays loudness wars.

Jiehfeng

Probably down to some of the implementations, not everything looks like what I'm referring to. I'm not talking about all scenes being too dark, just particular scenes that shouldn't be that dark, uber realism or not.

There's one I remember clearly, this scene from Endgame: https://m.youtube.com/watch?v=RgRjOIIzmiw

Jiehfeng

SDR looks normal, but the HDR of that scene makes it look too dark. But most of the movie's HDR is brilliant though.

S

SG854

Could be then how it was made. Darker room so darker lighting

I'll have to look at that scene on my OLED to see how it looks. I have Disney Plus. Recent LG OLED models have the same panel mostly difference is in features and processor.

But I'll need to recalibrate first as I F'd it up because I forgot to turn off Dynamic Tone Mapping.

Last time I calibrated was a year ago. So I was due for another one.

Lots of people say LCD are brighter so they are better. But even though OLED's don't get as bright as LCD's that doesn't mean brighter LCD's are way better.

The ultimate goal is 10,000 nit displays because that is the max range humans can precive at once. But that doesn't mean 10,000 nit HDR is 100 times brighter then SDR at 100 nits.

Human vision is not linear. It's logarithmic. So 5,000 nits is not half of the brightness of 10,000 nits. It is actually 100 nits that is 50% of the brightness of 10,000 nits.

100 nits is half way there, to our precieved brightness of 10k nit displays. 10,000 nits is only twice as bright as 100 nits. It's not 100 times brighter. And the higher up you go the diminishing returns you get in preceived brightness.

S

SG854

10,000 nits isn't as bright as people think. A Flower when we look outside reflecting the color red is 25,000 nits.

1,000 nits is not 4 times brighter then 250 nits. 1,000 nits is 75% of the brightness of 10,000 nits.
