Streaming 4K to Nvidia SHIELD

General Discussions
1

Hi,

Is it quite normal to have some lag issues with my Plex Media Server (good config) who stream 4k remux content (50-70Mbps & 40-50gb file) over Gigabit Ethernet to a shield (nvidia) client ?

I don’t know what to do to have a smooth playback until the end (sometimes I’ve something good but after a while it’s decreasing !)

I’ve already abandonned the TRUEHD 7.1 audio which complitely screw up … (different messages like not fast enough server or a problem with the network speed…)

I’ve checked so many solutions but none works.

Someone who is in the same situation ? Or it was just not possible today to play full 4K content over ethernet ?!

Thanks so much for the answer.

Some specs :

PMS on Windows 10 - i7 7700k 16gb ram w/ gtx 1080 (plex pass hardware accel ON)
Movie content on a raid 5 Hard Drive tower linked on USB 3 to the PMS
Plex client on Nvidia SHIELD TV, The Android Tv system on my philips oled 55pos9002 is worst by far from the shield… so…
All the house is covered with Gigabit cat 7 SSTP

Properbly the USB3 connection is the problem… Since I reconfigured my setup to SAS Drives and an propper server (HP Microserver gen8 with upgraded CPU) everything works fine.

Thanks for the reply.

I’ve also tested with an internal HDD and that doen’t change …
I don’t have a NAS but with this kind of problems that I have, I think of it ^^

USB3 is or at least should be fast enough.

All my 4K remuxes are on a mix of internal and an 8 bay USB 3 enclosure and play without issue.
I also have them duplicated on Google connected to a remote box and again they play fine in the Shield, Apple TV 4K and LG tv app.

Do you have applied some particular settings to have that work properly fine ? (server & client)

You have your Plex Media Server on a PC or on a NAS ?

On my Philips TV android it’s just to horrible to play (laggggg) so I’ve connected the SHIELD…

No i dont take any special steps.
Server runs on Windows 10.
I don’t use any said at all.
I tend to have all the 4K remuxes on separate drives to minimise anything else causing I/O to the drives.

Just to confirm its not the HDD use CrystalDiskMark and post the results.
