My sister has purchased a new LG 4k tv that runs WebOS 2.0. When playing a 4k youtube video, it actually plays in 4k (the 4k badge shows up when its playing in 4k). I'm on an older 4k tv running webOS 1. I can't get it to play 4k videos. It may be that i need to update my tv's firmware to a later version of webOS 1. Has anyone on WebOS 1 been able to stream 4k videos in 4k on their tv? Thanks in advance for any replies.
