YouTube 4K

Eltas — Wed, 28 Dec 2016 12:13:43 GMT

Some people, like myself may have experienced issues with 4K content on their 4K TVs on the YouTube app. I have the KU6400 and the recent update brought HDR to the YouTube app. Though 4K content is available on YouTube it only seems to play in 1080p. Apparently this has to do with Internet speeds. You have to be receiving 25MB speeds to be able to watch 4K on YouTube.

Hi MHJ!

Thanks for posting. The UE**KU6400 supports Standard HDR. Is the app fully up to date? What's your internet speed?

HDR works fine, I'm only getting 7.0mb WiFi download speeds. It's 4K on YouTube that's difficult to get.

Is the app up to date? Press and hold the Select button when the app is highlighted on the Smart Hub screen.

Better use Ethernet cable, Wifi is unreliable for video streaming.

Im have the same problem in fact still waiting for a email reply from Samsung, youtube 4k videos only work occasionally and my wifi is more than 50mbs download speed but much less than 20 at the tv so I have pluged in a TP-Link extender only rated at 300mps but I immediately received 4k.

I believe that the wifi receiver built in to the TV is of poor quality as it cant seem to receive the correct amount of internet.

Yeah, I have a problem with my WiFi booster. Most of the time it's not emitting the full 50mb it's supposed to, even the ethernet cable isn't reliable. I need to speak to my ISP. But I'm glad it's worked out for you. It's supposed to work for everyone

Re: YouTube 4K

Eltas — Wed, 04 Jan 2017 13:29:58 GMT

Yes, everything is up to date. It's a connection problem. And it doesn't say anyway on the YouTube app that 25MB is required to stream 4K

I have run speed test on my iphone 6S Plus and can receive more than 50mb download in the same position as the TV but that only receives a lot less than 20mb so I believe that the TV wifi card is either not working correctly or simply outdated Ill post more when Samsung get back to me about it.

It's odd that you mentioned that because my phone connects and works well with any WiFi connection, from the extended booster or from the actual hub. I connected my TV to the original hub and though the connection is weaker in terms of signal it's streaming full HD without buffering. Which is what it's been struggling with on the boosters ethernet connection. Hopefully Samsung will have a clearer answer to this.

What WiFi router do you have?

check with your phone using wifi analyzer if there is not a big interference from neighbors. If there is then try to change to most free WiFi channel, you could also try to use 13 channel which moslty is free but keep in mind that not all devices can connect to it.
disable 40Mhz mode(300 Mbit) as in 40Mhz mode router is switching back/forth from 20/40Mhz if there is interference which causes drop for a moment.
disable auto-channel and change to fixed WiFi channel. Auto channel switching causes drops in link quality
disable router Eco mode and set signal to high
Try to place router in different place as there could be reflection from objects which causes interference
make a DIY directional antenna for WiFi router using foil.
Use your router's 5GHz network if TV supports 5Ghz

Still I would recommend Ethernet cable if possible as WiFi is really not suitable for high bitrate video streaming it introduces lag (data is encrypted/decrypted by WiFi password), speed level is varying a lot (54 Mbps/48 Mbps/36 Mbps/24 Mbps etc) , additional unnecessary layer on top of ethernet. Too much issues which can be easily solved by switching to ethernet cable.

Eltas — Thu, 05 Jan 2017 08:13:01 GMT

Thanks, but as I said, the Ethernet cable is not reliable either, mainly because its connected to a my wifi booster, its not possible to connect to the hub because it is in a different part of the house.

Well I have had a reply from Samsung I can post it if required...

But I have a temporary fix... I have also sent this to Samsung and awaiting their reply but this is what I have done...

I have used a TP-Link wifi range extender (model no TL-WA850RE) this has a low output of only 300 Mbps and plugged in via an Ethernet cable to the TV so far in the test that I have made it seem to be working with 4K videos from YouTube playing in 4K with no buffering.

I have asked Samsung to comment on this as surely a smart TV costing £799 should not need a wifi extender to make it work when all other wireless items in the house are all fine much much further away from my router (my iPhone 6S plus will play YouTube videos in the garden at the rear of my house more than a 100 feet away through many walls).

Maybe more to come on this?

Re: YouTube 4K

oto — Thu, 05 Jan 2017 10:52:37 GMT

I doubt that Iphone 6S streams 4K video. Neverless it is not the booster model that I needed but main Wifi Hub. Is it also set to 300Mbps? I would recommend to disable 40Mhz channel as 300Mbs is very unrealiable and actually not needed as you dont'have 300Mbs Internet from ISP anyway.

Alternatively if you don't have option to install Ethernet cable you could try to use Powerline network - PLC adapters. It is ethernet over existing powerlines in house and it will have faster and more reliable speeds.

I'm in agreement with Oto here. If you want to make the most of streaming 4k content, you really want to have the most stable connection available you, the trusty cable -mapping over 8 million pixels is a lot of data. PLC adaptors are also great ways to get signal in the really awkward spots in your house.

Re: YouTube 4K

Eltas — Tue, 10 Jan 2017 19:15:11 GMT

This was just an informative post. I've gotten powerlines that give me the 100MB+ speed I wanted. But you need only to be receiving 25MB at to get 4K YouTube. Before the powerlines I was getting less than 1MB and so was barely able to stream 1080p.

Re: YouTube 4K

oto — Wed, 11 Jan 2017 11:37:07 GMT

Does PLC can well handle interference from other electrical appliances like hair dryers, drill, etc.?

Re: YouTube 4K

Eltas — Wed, 11 Jan 2017 11:47:12 GMT

Depends, it is not recommended that you plug them into an extension cord or adapter. its preferable to be straight into the wall socket. That being said I did the initial set up and test on an extension cord and it worked fine. Equally, I have the power line in a plug next to an extension cord that's connected to all sorts of gadgets and electricals and its working fine.

Can you check speed in fast.com or in Netflix app?

P.S. Spedtest.net seems to have issues with reliable measurements for Tizen browsers.
