I own a N2 and LG OLED G4.
Could you help me solve this old problem that I can’t find a solution for?
What are the CE settings for obtaining a clear, non-dark image when playing HDR10 video?
I have already tried numerous possibilities without success.
Furthermore, if you own an LG OLED TV, what are the TV settings for HDR10?
Thank you.
Are you having trouble with HDR10 or HDR10+? Your TV doesn’t support HDR10+ (HDR10 with dynamic metadata). For HDR10 to work, you need to enable HDMI Deep Color in your TV settings.
With HDR10, static metadata has the issue.
HDMI Deep Color was/is 4K (on) and get the issue.
Should I set on 4:4:4: Pass Through ?
NO. Just recalibrate one display mode so it reproduces correctly HDR10.
For example “Home Cinema” mod is calibrated for Dolby Vision playback, so when DV starts TV automatically selects that display mode.
Similarly calibrate “Cinema” mod to HDR10, so you get proper picture playback; then when you start any HDR10 video for first time manually choose “Cinema” display mod. After that it will be automatically selected every time a HDR10 video is started.
Let me know if I am wrong;
CE, same settings for all HDR/DV video files
System>Display:
Force display colour Depth: 10 bit
Force colour subsampling: Auto
System>Coreelec:
Tone map SDR to HDR: OFF
Tone map HDR to SDR: OFF
Player:
Adjust display HDR Mode: ON
TV Setting
Start playing video file and go to setting of the TV
If video is HDR10, HDR select mode: Cinema
If video is DV: DV select mode: Cinema home
I did the both, this is a lot better but still no details in dark areas.
Do you have a LG OLED? What are the settings?
Thanks
Yes, my is calibrated; “Cinema Home” for DV and “Cinema” is calibrated for HDR.
If you don’t have any means to do near/professional calibration, do like this:
First disable any power/eco mode!!!
Find a HDR video with prevailing black picture; when you get to a dark scene pause the video and open “Cinema” mod. Go to Advanced settings and make sure that “Gama” value is set to 2.2. Brightness and Contrast must be set to 100%. Now raise the “Black Level” value until you get satisfactory details in dark parts of the picture. Don’t over do it and make sure that the blackest part of the picture is as black as the black bezel surrounding your screen. Otherwise you’ll f*ckup the deep blacks your OLED screen is famous for 
Thank you Sholander,
This is now good. I watch in a dark room, no light at all. I had to set “Black Level” to 54. FYI, from 56 black become washed.
Now I need to know exactly what DV file I can watch.
AFAIK, P5, P8.1 are OK
What about P7 and BL, RPU, EL, MEL, FEL?
BTW, so far, I use Mediainfo. Is there a way to show the complete profile in CE or LG TV? I haven’t see it.
BL at 54 is “normal”, it depends on the panel. On some LG Oleds I had to rise it to low 60 for satisfactory results.
P5 is not possible, at the moment; for the rest → try them
