I’ve been having some issues with Android 8.0 and 9.0. Last time was with Sony Bravia 85" and now with 50BDL4550d from Philips. I’ve tryed different rotation screen apps and none seems to work. Then there’s the possibility of making it on the screen settings. It rotates the screen but then i get the squeezed imaged on the centre of the screen. I’ve changed the setting with and without overide of screen dimensions but it’s not working.
I’m using Version 1.8.13 of CMS by the way.
I got it solved… I’ll let the note: As usual, the screen is 4K but when in portrait, the player actas 1080x1920
All the best!
