Im wanting to change/upgrade my current Samsung UE40F6500 thats in the bedroom. Obviously wanting to go to 4K but confused with all the Hed,hdr Ultra. Is 4k Ultra HDR the best to go for other than OLED? The tv needs to have ( hence the upgrade ) option to connect to my bluetooth headphones for when the misses falls asleep. Also wall mountable and able to run Plex. Can anyone offer and help/advise. Many thanks, Dave Happy New Year.
