Hello all,
From what I can tell, this may not be supported anymore. I am on webOS TV Version 7.1.0-68 (mullet-maria).
I just purchased an OLED 42 inch C2. When I select Multiview, the two hdmi ports are not an available combination.
I have turned of CEC (now SIMPLINK) for both HDMI inputs as I read in a post from 2018.
Thank you,
Brendan
