I'm having trouble setting this game's HDR mode up.
TV: LGUH7700
Black level: I configured my HDR mode TV settings based on TLoU (Left Behind to be precise). Black level set to high on TV and PS4 RGB setting is set to Full.
General settings: I configured the non-HDR mode for the PS4/HDMI based on review settings for this TV and my preference for color temp etc.
For HDR mode, I configured the preset mode so that it would basically look the same as the non-HDR mode in terms of color temp, saturation etc.
I think this the correct way as the you should not actually see different colors or whatever when switching a game to HDR mode. With my setup the switch just makes the colors more nuanced and most obvious difference is the HDR itself: Piercing brights e.g. in the sky with deep blacks in the same image. But moving to a bright area won't look too bright and looking at a dark area won't just show black but you can make out the details. That's how our eyes work and is the main point of any HDR implementation.
e.g. for Ratchet&Clank I didn't need to change anything after my initial configuration, it just looked right.
But for Deus Ex, I immediately had to switch the TV black level to low as the image was obviously washed out. I did not change any other settings on the TV or PS4 (see above) and tried to get the picture look right using the ingame brightness setting.
I think the image in outside areas still looks too washed out compared to non-HDR mode but reducing the ingame brightness just gives me weird bloom-ish artifacts on bright surfaces. I have to set the brightness higher than what the text tells you to ("until icon barely visible" etc.) to get rid of that, but I still want to make the image less washed out.
For reference:
non-HDR 0% Brightness:
non-HDR 25% Brightness (set to icon visibility):
non-HDR 100% Brightness:
HDR 0% Brightness:
HDR 35% Brightness (set to icon visibility):
HDR 100% Brightness:
In the HDR 0% Brightness image you can see the mentioned artifact in the face.
So the brightness setting in HDR doesn't actually do the same as in non-HDR mode (making it darker/brighter) but is more like a setoff option or something?
Changing the brightness on the TV doesn't give a good result either, not to mention that I simply do NOT want to change my TV settings for each game. Changing the black level already annoys me.
edit: indoors it looks mostly fine so maybe I just don't agree with their outdoor look in HDR.
