Xbox One: Crushed blacks & RGB settings broken?

#1
So this is a very different issue that cropped up in the Xbox One Scaler Thread, which was more concerning sharpening. I thought this subject deserved it's own thread to figure just what exactly is happening since it seemed to be derailing the other thread.

In short user Timu has been a kind and active contributor to the console screenshot thread. As he was posting screenshots of Xbox One games other users pointed out that his screenshots were sporting severely crushed blacks. Most of us thought it had to due with Full Range RGB being set and possibly causing some trouble after that Digital Foundry BF3 comparison. In turn we requested that he take some screengrabs with the system set to Limited RGB and see what happened. At the very least we expected the black level to be reduced and yet, here are the screens he took.

This is with RGB set to full:


and these are with RGB set to limited:



He's posted some other photos from DR3 with the gamma cranked up to attempt to compensate for the lack of detail, and yet the problem still persists:
Ok, here's Dead Rising 3, and I increased the gamma because it looked way worse than before.



If this has been covered before, or if there's merely something wrong with his captures please lock the thread. But at the very least I thought this would make for an interesting discussion in pinning down what could be going wrong either in the Xbox One's output or in Timu's method of capturing.

I have a tv that supports full rgb, in addition to limited. I have tried messing around with both, then checking the black and contrast levels via the xbox one calibration tool and i haven't noticed any crushed blacks whatsoever. What i have noticed is that when i set both the tv and xbox to full rgb, the picture is a little brighter as it should be (16-235) vs (0-255). No issues for me so far.

Edit: I tested this with Ryse. Full rgb looks a little better than limited where it looks a little dull.

well does cable television or fantasy football really need blacks

edit: wait this sounds really racist and totally not what i mean
lol I read this before the edit and I was totally thinking "I don't think he is being racist and I think I get what he is trying to to say but I wonder if he realizes this could be taken the wrong way" nice edit.

I don't know what crushed blacks are, but when I set the RGB to full, the dash goes reeeeeeeally black.


It's essentially a loss of detail in the darker color ranges. Where you should see gradations of color you only see a flat black surface. Unless your television also supports a Full Range setting, just keep it set to limited. Although I'm not sure that makes a difference with the way the console is currently set.

I knew what he meant too, I just found it hilarious.

My tv allegedly handles rgb full and it worked great on 360 but on the One the calibration tool doesn't allow me to see the dark closed eye in full only limited

So thought maybe it is messed up

It's not just full range that crushes the blacks in certain games. Limited range has the same problem. It's mainly a problem in Dead Rising 3 and Killer Instinct. Changing gamma settings in game doesn't help as noted. It makes me not want to play Dead Rising 3 since it's SOOOOO dark. It isn't a problem in Ryse.

Even the RGB limited shots still look to have crushed blacks, so yes, it's probably messed up. On a side note, this shot does no favours for KI graphically...wow....

The 1st shot is Full RGB but the rest are Limited RGB. I also increased the Gamma for Dead Rising 3 in those shots to near full, and KI has no real brightness/contrast options, I might have to increase the brightness of that game with my capture card.

Also I don't think Crimson Dragon has this problem but I heard that was in 1080p.

The Killer Instinct shots aren't nice but at least it doesn't really interfere with the gameplay. It's just unfortunate that the background is just one giant black hole (and increased aliasing). But the Dead Rising shots are horrible. If you can't see what's around you then it'd be a nightmare trying to fend off the zombies.

I have this problem with Blu-Rays and the Xbox One. I was watching the new Superman this morning and noticed the crush black effect at the beginning on Krypton. The blacks are so deep and flat that you can't notice the detail in Zod or Jor-El's suit. I had to jack my black level up another 15 points on my movie settings that I've had calibrated and been using for months. Also,in Dead Rising I had to set the gamma to one below full. Setting it to Limited did fix this problem though on the 360 it wasn't an issue.

How would I change gamma settings on my asus vg23ah? I noticed some possibly crushed blacks while playing ps4 and I set the ps4 to limited but would like to know how to get the best picture possible. I'd appreciate a PM reply.
 
#35
Not really related, but the PS4's built in video recording seems to crush blacks as well. I was watching some night time AC4 footage that I recorded and there was absolutely no detail in the darker areas when I know that's not the case for the actual game.

If the crushed blacks are in the source picture there's nothing you can do about it. You can't make more details appear from a picture they were erased from.

Edit: Oh wait you're talking about the PS4.

Monitor OSDs are straightfoward, you should be able to find the gamma setting easily if it has one. You should also Google to find out other people's experience with calibrating that model.

I remember this bug in one of the 360 dashboard updates. Was annoying.

Make some noise and maybe they will fix it in an update.

720p upscaled to 1080p with an aggressive sharpening filter applied.

It butchers what little IQ the game had in the first place.

is limited and full the only options? 360 has standard which is what most people need to use and another option as well if I remember correctly.

Ok, I did some adjustments, this is DR3 on highest gamma without touching the capture card brightness:



For KI, I had to increase the brightness from my capture card, I'll show the differences between default 128, then 140 and then 150:

128:


140:

In this Dead Rising shot, you've gained brightness at the expense of black level depth. Blacks are now closer to a grey like hue, and the shadow detail is still lacking. It's an alternative to dealing with black crush no doubt, but by no means a solution to the problem. Just replaces one issue with another.

Going to have to adjust the gamma or brightness to fix that, lol.
