Hi everyone so I searched high and low for a solution to my issue with Windows 10 and Screen Cast on my LG UK6300PUE not working and finally found a solution.
For me, it had to do with my PC and TV connections. I like to hard wire everything and with both my PC and TV, they default to the more reliable, wired connection and disconnect the WiFi.
Well from what I understand, Screen Cast is based off of Intel's WiDi technology, WHICH REQUIRES WIFI CONNECTIONS TO WORK!
I did go through all the other suggestions, checking share settings in Windows and Media Player, resetting this and that. I'm not sure if I had to do any of that for Screen Cast to work but I did try all those common suggestion initially. So if Screen Cast is still not working for you, try those other suggestions posted in numerous places here and other forums.
I'm really surprised on all the forums I visited, this wasn't pointed out anywhere! I hope this helps those having issues with Screen Cast!
TL; DR: So basically on a WIRED connection, I could see my TV on my Windows 10 PC, but it would not connect. As soon as I connected BOTH my PC AND TV to WiFi, Screen Cast began to work.
My current LG UK6300PUE Software Version: 04.10.04
Windows 10 64-bit Build: Version 1803, OS Build 17134.34
Short answer: Something on my network is causing the crashes.
I had an extra router, so I put it between my network and the TV.
Netflix no longer crashes, and other apps no longer give me the dreaded, "This app will now restart to free up more memory" error.
Longer answer: Netflix would regularly crash out to Live TV after 20-40 minutes of play. I've been on LG support with this for months. They've replaced the main board twice, and took it off-site where the problem could not be replicated.
I reset the TV and connected it to my smart phone data plan (luckily just upgraded to 10 GB). No crashes. Put the TV back on my network, crashed after half an hour.
I took the network cable out of the TV and plugged it into a spare WiFi router. This creates a small network of only one device (the TV). I no longer get crashes.
Unfortunately, this kills local network features like DLNA/Plex streaming and wireless display mirroring, but all Internet apps like Netflix and YouTube work flawlessly.
I plan to narrow down which device(s) on my network is the cause of the crashes, but after 10 months of fighting this I'm just going to enjoy some 4K streaming for a while. If I learn anything new, I'll post it here.
I have been having problems watching movies on LG web browser on my smart Tv. But I have downloaded a TV cast app on my iPhone and on my Tv off LG App Store. Now using these apps I can stream movies onto smart Tv using Tv cast app and it dose not crash or say App will now will restart to free up memory.
