Since a few days, I do not have the possibility to watch videos on the application youtube of my TV LG 49UB850V in 4K.
In the settings, it stops at 1080p.
I have a very good internet connection (fiber optic), and especially, there are still a few weeks, I could do it without problem.
A test video of youtube in 4K is only available in 1080p on my tv, while on the computer, it is available in 4K.
On my most recent LG 55C8 also by the way, the 4K is possible on this same video. I did the test with lots of videos, same result.
LG does not know how to solve the problem, I uninstalled and reinstalled the application but it does not change anything.
I did nothing special on my TV before this change, it is done overnight. Do you have the same problem?
