I have an LG OLED55B8PLA and Apple TV 4K and black is not as it supposed to be on oled. For example on movies the up and down black line is lightened…not dark.
If there is a full black transition on the movie…the oled display will remain with light on….not fully dark.
I tested the same movie on infuse (and have this issue) and also on a usb stick and everything looks fine in usb stick.
On Apple TV settings, match content are are both ON.
Check images 1st image is from Infuse.
Most newer TVs can have different settings for different HDMI inputs, and playback via the TV’s internal player will usually use different settings altogether.
Edit: You can also try enabling ‘True Black Mode’ in Infuse > Settings. With this on, the background color in the app while browsing will be pure black. If this doesn’t appear pure black for you, it may indicate an issue with your TV’s settings.
Tested mkv file DV with VLC and PLEX and black is pure black.
Tested mkv file HDR with VLC (black is pure) and on PLEX black is washed.
One thing that i noticed…on every mkv file played on Infuse when i play TV sets to HDR…even if the file is DV.
By default my ATV is set on video format to 4K DV and the background color of the app si pure place. If i change the VIDEO FORMAT on ATV from 4K DV to 4K HDR the the background is washed like in my 2nd post.
EDIT: As i can see this washed black is a problem from ATV. On every movie with HDR…doesn’t matter from what app i play have the same problem (tested on amazon prime…same problem with washed black)
So the question then is…why Infuse selects every mkv file ad HDR even if it’s DV thanks
Since this is also affecting HDR output of the UI itself (when using Pure Black Mode) I believe there is either an issue with the HDMI cable, or with the settings on the TV.
Is the Apple TV connected directly to the TV? If so, you may try switching HDMI cables, HDMI ports, and adjusting the HDR video settings on the TV.
Note: You’ll want to ensure HDR video output is enabled before adjusting settings, as each input mode will have different settings options, and these can only be adjusted when the corresponding mode (SDR, HDR, DV) is active.
Ok…so i found the problem. Somehow some settings were reseted i guess after an update from TV.
The CONTRAST from picture mode was set to 100 (even if i know for sure i set it to 90 when i calibrate it long time ago). So it’s an LG bug…if you set the contrast to 99 for example will have the true black back
