OK, got a Vero 4K as well as an LG OLED65C8 recently and they work fine together. One thing troubles me though.
First thing I did before even playing anything was to “Enable HDR autoswitching”. Then HDR files (demos found on the net, bluray rips) randomly refused to play (TV says “no input”).
As soon as HDR autoswitch is disabled, everything plays flawlessly, and TV switches back and forth between SDR and HDR, colors/brightness are just fine.
First question is, whitch resolution did you set? You should go with 1080p since it performs better and Kodi Scaling isnt quite the best out there. Second positive thing is that your TV does the upscaling on 1080p content.
Normally, HDR autoswitch switches between two colorspaces to give you accurate colors in both HDR and SDR. (BT.2020 and BT.709 (Rec.709)). Your TV should show the ‘HDR enabled’ banner on the right left corner.
I do have an LG 55C7 and HDR switching does work just fine, but only if resolution in settings is set to 1080p (which is better anyways cause you want the TV to upscale lower res content).
I don´t know how autoswitch does work exactly, but my guess is that the player is able to read metadata in which the correct colorspace is documented.
With OSMC resolution set to 1080p or 2060p --> same issue.
I have decent HDMI cables. Nevertheless, I tried another (decent) one, same issue.
The Vero 4K is plugged into the TV directly, no receiver.
With HDR autoswitching ENABLED and trying to play an HDR stream, randomly (AFAICT), the TV switches to HDR (HDR logo in the upper right corner, I guess the TV receives the HDR metadata), then a couple of seconds later I get “No signal”. It seems OSMC is somehow “playing” the stream since I can see the external HDD led flashing. FYI, no problem at all with SDR streams.
The funny thing is that, all plays well exactly as expected (BT.2020 vs BT.709 as reported by the TV) automatically with HDR autoswitching DISABLED.
Just a quick feedback after the “2018.06-1” update. HDR autoswitching is still not working for me. It behaves a little differently though. This time, the HDR stream plays fine for a few seconds then somehow stops and the TV complains there is no signal.
I’m now back with HDR autoswitching disabled and 10 bit output forced since it clearly improves banding / posterization.
I’ve just got my Vero 4k+ and attached to my LG OLED C8, and i’m having trouble with
the “no signal” after starting HDR content. It should be fully updated.
The screen comes back after I stop the content. If I stop and start a few times, sometimes it works.
It seems related to the display resolution, It was running in 720p initially and the HDR content worked fine, switching to 4k resolution caused the problem, (potentially also changing the delay after switch setting made it worse still)
Its when i power on the vero without the tv on or something that makes it go into that funny state where you cant change resolution/framerate in settings/system/display…
It was stuck to 720p then, but hdr content played fine without the no signal problem, but stuck in 720p. After a reboot framerate/res switching works again but then the hdr content triggers the “no signal”, unless i stop and start and stop and start a few times.
