So, today I have encountered a very unexpected problem. Though, after googling around I found that I am by far not the first nor will I likely be the fast.
I found out (the hard way) that my TV only has a 100Mbit Ethernet port and the WiFi speeds are similarly limited.
It's usually not a problem, but after using it for mostly gaming (have a PS4 Pro), I decided to try out it's full capabilities and get some 4K UHD HDR rips and try to play em using Plex.
And... well, what do you know? "Network speed insufficient to stream".
Given that this TV is running Android, I was wondering if there were any USB2.0toEthernet or USB3.0toEthernet adapters available that support it so I can stream those kinds of large files, or if it's a closed case of Sony (and, apparently, other manufacturers) being idiots?
Like I didn't even think to check what speed the ethernet port was before buying, because it honestly boggles my mind that such expensive electronics can have such limitations in 2017. If I knew it would'a been enough of a downside I would have chosen a different model :/ Oh well, now I know, I suppose.
You should still be able to play 4k HDR videos that are encoded with HEVC/H.265 acceptably at that speed. Make sure that Plex isn't doing any transcoding.
