New to Plex, just got a 4k TV

Hi all.

I’m new here, so perhaps this is the wrong place for my questions. Admin please move or delete my post if so.

I just bought my first 4k TV, an LG 75SK8100PLA, and now I’m trying to find out the best way to get 4k content to it. The TV has both a LAN port and 802.11ac wifi.

I have a desktop computer and a router relatively close by, and I’m wondering if I can use my computer as a storage/ stream source for the TV to view content optimally. For this purpose I understand Plex could be what I am looking for, as I can run Plex on the computer and on the TV using an app.

The computers specs are:
I7-8700k (stock speeds)
1080TI GPU (stock speeds)
16Gb 3000MHz RAM (stock speeds)
ASUS ROG Maximus X Hero motherboard
Large capacity 7200RPM Seagate Barracuda HDD
1TB SSD
Connected to router by cable, routher has 5GHz wifi.

-Would I be able to stream high quality 4k content with my current hardware?
-Will the HDD be capable of the speeds required?
-What would be the best way to interface the TV and the computer?
-Could good results be achieved wirelessly?

Thank you.

Erik, Welcome to PLEX. For starters and what I’ve found building my own streaming home network, transmission speeds on your network will be key, if you want to stream to a device at 720p, 1080p, or 4K. Each has it’s own bandwidth it likes to run at for smooth clear streaming. I’ve found your higher rates like 1080p and 4k, you are going to need LAN speeds, depending on how many devices you have in your home.

What you show for specs are well within the specs needed. I have a 2.8 Quadcore Intel machine as my PMS, with duel Network cards one to allow for full bandwidth to my internal network and one network card to supply to my external network for streaming across the internet when I’m away from home.

Don’t sweat this, because your next best friend are devices called Ethernet over Powerline. Which allow you to use your existing powerlines within your home to achieve LAN speeds where WiFi just can get to, especially for TV Streaming.

What I’ve found on average a good 1080p stream needs anywhere from 15 Mbs to 22 Mbs, for one single stream. So depending on the amount of devices you have on your network and what they are doing this will slow things down. Luckily with today’s wireless routers they can gauge this so that your devices are equally sharing your network. With a 4k stream, your talking of speeds much higher than 1080p. I only have a 1080p TV in my home to honestly give you the data rates I see when streaming. I only have 2 TV sets, but I also can stream to iPads and phones at the same time. As well as record 4 shows, recording from 15Mbs to 1.5 Mbs, per channel or recording, of over the air broadcasts on my 1Gb network, to my PLEX Media Server. So again, with these devices using Ethernet over Powerline, this should aid you with 4k Streaming.

Next, do you have any true 4k media? I’m pretty sure right now there is not any TV over the air broadcasting in 4k yet. I do know 1080p is for sure. But I believe NETFLIX and some of the other streams can stream at that. Recording that, might be a challenge, but you may have to research if there are devices now that can record it to your plex media server. I built my PLEX Media Server a few years ago with my network when 4k was in its infancy. So possibly there are recording devices out there that can allow you to get your 4k media to your PMS storage to stream. I just don’t know.

Hopefully this helps on some of my own research I’ve done to help you on your way to how you want to use PLEX for.

My PMS:
Intel® Core™2 Quad CPU Q9550 @ 2.83GHz

More info, since you got me curious on this topic:

4K and The Future of Over-the-Air Broadcast TV

There are no 4K Over-the-Air TV broadcasts available today. However, the FCC has approved the voluntary rollout of a newer broadcast TV standard known as ATSC 3.0 which – among other benefits – does support beautiful 4K UHD picture quality.

What About 4K TV Antennas?
Even though some Over-the-Air TV antennas are being marketed as being ‘4K-ready’, ALL TV antennas sold in North America can pick up the current ATSC 1.0 as well as any 4K ATSC 3.0 broadcasts available in the future. As mentioned previously, the ‘magic’ in accessing future 4K OTA TV broadcasts will come from the tuner connected to that antenna, so don’t choose one TV antenna over another based solely on 4K claims.

Should I Wait to Buy Over-the-Air Cord Cutting Gear?
You could wait… But it may be several more years before 4K ATSC 3.0 signals and products are widely available. Between now and then, cutting the cord could help you save a significant amount of money compared to cable TV.

Plus, any station that moves to ATSC 3.0 is required to maintain ATSC 1.0 broadcasts for an additional 5 years after completing their transition. That extends the usefulness of current-generation ATSC 1.0 cord cutting equipment including televisions, DVRs, tuner devices, and more into 2024 and beyond.

Long story short, if you’re thinking of buying in an Over-the-Air antenna or other broadcast TV technology as part of your overall cord cutting plans, you can consider it a sound investment.

All of what RazorBlades is true, in general. One thing that needs to be considered is the playback devices. The other is file types and their codecs.

Before you spend time and money installing a wired network. You should consider whether your going to use a Roku, Fire tv, Nvidia shield, Smart tv, etc. Then look at the Ethernet device speeds. For example, Smart tv’s (for some unknown reason) only have 100 mbps lan ports. Some on here have stated that 4K streams and transcodes can need speeds from 115-145 mbps. Which you can see would cause buffering issues. A direct playing situation of 4k may only require around 80 mbps and no issues. And if you want to do wireless then you need to consider your router and the amount of devices in the home.

Which brings me to the file codecs. You have video (264,265,ts), audio (DTS, AC3, AAC) and subtitles to consider. The key to consistency and reliability of the system from my experience is to have all the content to Direct Play. You need to check the devises you plan on using and to insure they can direct play the content that you have saved on the computer.

Smart tv’s are usually the simplest of the players, they can also have buffering issues because the content may have one or more codecs that can not direct play. For example, 2018 Samsung tv’s can’t play DTS audio. So the computer has to Direct Stream the content, and many have experienced buffering due to network or Plex software bugs (are annoying when they happen until they get fixed). Direct Playing eliminates these issues.

Thanks a lot for the thorough reply, RazorBlades.

I’ll wire the two together using either an ethernet cable between them or the Powerline solution. I think I can pull an ethernet cable in my walls from the router to the TV, or directly from the desktop computer to the TV, but if not then the Powerline solution is a good backup.

I don’t watch regular TV channels. The constant commercial breaks ruin the movie/ series experience and is kinda infuriating. I guess I’m not a very patient fellow when it comes to commercials. So, my entertainment that I will watch on the TV will be either Netflix/ HBO/ etc or high quality movies I have downloaded or have on discs. The downloaded movies and/ or discs will be the only true 4k content. I’m in Norway, and things are kinda slow here when it comes to new TV broadcast tech.

Currently the load on my router would be from just the TV and a couple of phones, so router capacity should hopefully not be an issue. At least not for anything less than 4k.

Have I understood the function of Plex correctly? Can I run the Plex software on my desktop and it will index my movies, and with the desktop connected to the TV over LAN (either directly or via the router) and the Plex app on the TV I can access those movies?

You should be in good shape. Plex will index your content very well. It will even put things in collections for easier binge watching of movies. The app will allow you to access all the content on the server and can also allow you to watch you shows when away from home.

There is one other thing worth considering if you to plan to use the Plex app on your LG tv.

Though it’s always best to have the server hardwired to the router, it’s not always with case with the client.
Most tv’s still don’t carry gigabit Ethernet ports.

So it’s very possible that with extremely high bitrate 4K you may actually have more luck with Wireless AC.

I just last week, had to replace my tvs due to lightning. I have a new 75in LG running webOS 4. It amazingly direct plays most of my 4k files over wireless AC, from the built in Plex app, where as my older 65in LG 4Ks that were running webos 2 and webos 3 rarely direct played any 4K and transcoding and buffering started making it near impossible to watch on those.

Thanks all.

From what I can see the TV supports HEVC (H.265), SHVC (never heard of), and VP9. If direct play is beneficial, I should target content of any of these formats if the content is stored on the desktop. Correct?

Supported audio is AC4, AC3(Dolby Digital), EAC3, HE-AAC, AAC, MP2, MP3, PCM, DTS, DTS-HD, DTS Express, WMA, apt-X according to the product info page.

I’ve sent LG a message on facebook asking if they recommend using the LAN port on the TV or the wifi, and what version of WebOS the TV runs (the info page does not mention it).

Bad luck with the lightning osu1991… Hopefully your insurance covered you.

No problem all, glad to share some input with what I designed on my own, using PLEX.

Nice thing Erik, is PLEX will help determine what CODECS for audio is needed at the other end. Then with it’s ability to TRANSCODE, help produce the audio that your device needs so that you can hear it. Which is way cool.

The third party program I use for my video content to allow what is referred to “Direct Play”, is that you’ve matched the audio to your CODEC and Video playing device. Which in turns allows for your stream to go to it’s max, from what I’ve found. And the stream be less bandwidth, for your network and less work your PLEX Media Server has to do for that device. I use the HandBrakeCLI program on my Linux Server. And have developed some scripts for things with it. I would sure like to be able to share some of these with the PLEX community, maybe here in the next few days. What I have put together for what I use on a daily basis is one kick butt setup. My wife, who was very picky on watching recorded shows, and being able to not have to wait like yourself for commercials. I have stream lined with the help of PLEX to do this and have a DVR media server do things in the background, without much I have to do. Almost think would be a good commercial product that most would buy and kick their DVR system’s to the curb. But with PLEX being free, with just me paying for the PLEX Pass, for having the ability to record my over the air shows, I’m grateful PLEX came around when it did.

In short, my set consists of the following:

2 - HDTV 50 mile range flat panel antenna’s, that are ganged together using a splitter “flipped” of a high in HD signal quality, and equal cable lengths from both antenna’s to provide no signal overlap or shadowing. So the splitter is 2 inputs to a single output. This is to allow maximum passthru of OTA (Over The Air) signal going to the 2 HDHomeRun DVR boxes I have, and normal antenna coax going to my 2 TV’s in the house, using a single to triple splitter, again, high quality HD COAX OTA passthru. For this I have a single input splitter, to a triple output. 1 input to one HomeRun DVR, the 2nd input to the 2nd HomeRun DVR, and the 3rd, going down to the 2 TV’s, that are split on last time. I have a booster on the line, but is not needed for most channels, just the far ones, which I get over 60 miles away.

Using PLEX, and PLEX Pass to record from the HomeRun DVR 2 channel units, I can record 4 shows at the same time while streaming to multiple devices at the same time with no buffer. I say that, cause I convert my content after recording to web stream-able 720p and 1080p with universal CODECS respectively using HandBrakeCLI . Which the sound is great on my Dolby 3.1 LG sound bar I use on my 42 LCD screen in the living room. For my 2 TV’s I’m using a Android device, that is connected to the HDMI port of the TV, so I can get the 1080p and 1080i output on the screen. Which for what the cable company signal, my signal looks like 4k on the 1080p screen. It’s breath taking, and why I kicked my cable TV company to the curb for TV these days. OTA simply ROCKs! I have 39 channels of Over the Air to choose from, so I’m more than happy with my local content. For anything else, like some cable / sports channels, I stream them using another app directly to my Android boxes connected to the TV’s or PC’s / tablets in the house.

The normal coax going to the TV’s are if I want to watch the OTA TV shows, without having to stream them. Which both my TV’s will do. This way I free up my bandwidth for other devices, so they can be streamed to and have more network access for it. It’s a win, win in my book.

So in a nut shell, I can be recording 4 shows while I watch a 5th and 6th show live, in both rooms. How cool is that ??? VERY !!

RazorBlades you certainly seem to know your stuff! Indeed very cool!

I will start out small, with just the desktop and the TV and see how that works.

Thanks a lot for all the input guys.

Just got my TV set up and connected, and so far I’m not getting the results I where hoping for…

Small 1080p movies stream fine from the desktop, but 2160p movies (30-50GB) do not. Buffering is a big issue both on LAN and WIFI.

Perhaps I need a new router?

Update: 1080p movies work fine for a couple of minutes a time, then need to buffer for 10~ seconds.

First thing to check is Desktop client /Web Client is the activity function for dashboard- Detailed.

Is 4k Title Trans coding, if so there may lie your issue.

Could you be more detailed please?

Assuming you are on the latest server version.
Access your server via Plex.tv (it doesn’t currently work via localhost).
From there click the actity button towards the top right.
That will tell you if the file is direct playing or transcoding.

As per screenshot.

From a Title your having issue with click on the Ellipsis at bottom right (…), click on Get info and the xml save as a text file and post. Screenshot will give example:

Then have a look at following support page:

https://support.plex.tv/articles/203810286-what-media-formats-are-supported/

Thanks a lot SE56.

The movies I have tried so far are direct playing.

I went basic and restarted the TV, and what do you know… Streaming 2160p over LAN works great now :smile:

For developing HD 1080p video for your 4k Ultra HD TV for normal 1080p broadcasts to play and look as good as the original broadcast with English audio tracks, use the following HandBrakeCLI command (example):

echo "" | HandBrakeCLI -i "$1" -o "$2" --audio-lang-list eng --all-audio --first-audio --preset "Very Fast 1080p30" --optimize --two-pass --turbo --aencoder av_aac --mixdown 5point1 --adither auto --auto-anamorphic

Been using this for my 4k Ultra Samsung 65 inch Q7 series TV, and my playback is awesome! The PLEX App for the TV work great !!!
