Gaming laptop can't stream 4k on Plex media player

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.

solved it myself. if an admin sees this you may delete it.
