I’ve been hosting my plex server for months now with no issues. My Gaming pc can stream 4k playback via windows plex player same goes with my Samsung smart TV. I have a rather old gaming laptop at least from 2016 and it still has modern specs and can run 4k data natively. But if I use the plex player I get either low 4k framerates or the media would just crash.
Server specs:
i7 4790 Integrated graphics
16GB RAM
120GB SSD
10TB Hard drive
Gaming laptop that has issues (4k playback
i7 6700hq/ Nvidia GTX 960m /8GB
Gaming PC that has no problems streaming 4k
Ryzen 5 2600
GTX 1660 super
32GB RAM
Everything is wired via cat 6 at 600mbps up and down. and I have plex pass as well.
I’m not sure why there would be issues streaming 4k on an i7 laptop with a rather modern graphics card.
