Hi Mihai B,
A gigabit connection is not required for streaming 4K to a local device:
Even if it required 100Mbps a properly set up network would handle it fine.
Depending on how much data you are slinging around the network, whether you have a managed/smart network hub, how you have your Plex server set up and many other factors can cause issues.
I had my IT department on the phone with me and LG support and we tried everything. Tried different ports, cables, all the different ways LG said and nothing worked. The reset, trying to go through google, just couldn't bring up the service agreement. LG is sending a service out to look at my TV. I had to take it off the mount to be services. I have bought 6- 65", a 49, and 43" and this is the first time this has ever happened and it happened to be the TV for my office. I was happy to pay more for LG products because i have never had any problems and they were quality products. I am questioning this decision right now.
Is there any way of installing an usb gigabit network adapter on a webos smart TV? The builtin wired adapter is only 100mbps (on a 2000$+ TV, shame on you LG!!!) while the wifi (N) is very poor, with the router at 1m from TV it only gets half the bandwidth of the wired network. Anyway the wired network maxes out near 100mbps but I need more bandwidth as I have 4k video content with bitrates grater than 100mbps which I cannot stream without stuttering to TV through XPLAY/PLEX.
LG has announced an Open Source Edition of its webOS operating it currently uses for its smart televisions. Currently, the Korean company has released an open source version that is specifically aimed towards use on the Raspberry Pi 3 microcomputer, but they want webOS to expand to other devices as well.
The open source version of webOS is the result of an agreement with the Korean National IT Industry Promotion Agency, and LG hopes that the software will of use for start-ups in their home country. The company hopes to expand the use and reach of webOS to a plethora of devices.
An SDK has been released for developers as well as a number of technical documents. The webOS Open Source Edition currently is optimized for the Raspberry Pi 3, but also runs on devices with an Ubuntu 14.04 64bit LTS operating system. For reasons unknown, it’s not recommended to run the operating system in a virtual environment.
Buy a Rasberry Pi kit on Amazon

I had same problem. I can record onto USB but not use live playback. Emailed LG. They said for live playback you need an external hard drive. Bought the cheapest one I could find and Live Playback now works fine
I now have an issue with what appears to be back light screen bleeding from the bottom corners of my screen on a 49UF6900, particularly when the video is light. Would anyone having experienced bleed on their screen have a solution or does it need a tech to resolve/repair?
