How do you make the most of the 4K screen? - Xperia Z5 Premium Q&A, Help & Troubleshooting

I was wondering what apps everyone uses to make the most of the 4K screen?

youtube in 4k works in chrome browser when set in desktop site and when enabling hardware acceleration in vlc player it will be able to display in 4k (tested with a demo video)

Does Twitter run in 4K now?
It seems considerably sharper to me than other apps

playing 4k video on exynos octa (SPM-600)?

Any1 here had any success playing 4k vids on the exynos variant? If so pls link the video u played.
My note cant handle 4k mp4's recorded with note 3 w/o significant stutter/very low fps and sound cutting off, tried BSS, Vplayer, MX and Archos (with codecs, and both H/W & S/W decoding if available, closing all background apps, etc).
I'll try converting 4k vids to 1600p, if possible, with Vegas 12 later today..
We have an amazing display with a decent SoC, i'd really like to see what its capable of at maximum resolution, 1080p just doesnt cut it.
I tried 4K video on youtube (via flash player inside Firefox) on Note 10.1 2014.
Result: Crash.
1080p plays fine using the exact same pathway.
Youtube app will not even enable selecting the original 4K video version inside youtube.
i thought they posted a while back that the exynos5 note 3 couldn't playback the superhd videos it took so it shouldn't be a surprize that this one won't either. kinda odd that they can't though.
The Exynos 2014 Note 10.1 can play back 2 Full-HD streams simultaneously without any hickup. 4K playback might be a bit too much.

Youtube 1080p content with Fire TV

I used to use Apple TV to play youtube and 1080p content looks great. But when I tried youtube on Fire TV, it is at most SD, not 720p, not 1080p and it looks blurred! I assume Amazon crippled it (Same is true to XBOX 360 and one).
Is there anyway to let Fire TV to play youtube 1080p? Or I still have to use Apple TV for youtube.

I just passed my Fire TV internet connection through Wireshark, a packet analyzer, and played several videos through the YouTube app that had 1080p as an option on the website. The "itag" parameter (which determines the video resolution) of the HTTP requests to YouTube was always either 136 or 137. It flip flopped between these two values randomly. According to this document, 136 refers to 1280 x 720 MP4, and 137 refers to 1920 x 1080 MP4. I verified the video resolution matched the itag value by pasting the requested video URL into a browser and downloading the returned video segment.
That leads me to believe that the video quality is variable and selected based on your connection characteristics. So if you're seeing poor quality video, then either your ISP is throttling you, or YouTube has decided your connection is insufficient for 720p or 1080p.

I tried both Apple TV and Fire TV, with the same youtube account with the same video program saved in playlist. I can easily tell with ATV the video quality is 1080p (I can tell the difference on ATV with 1080p/720p/480p). But on Fire TV or XBOX, it is always lowest quality (maybe 480p). So I am pretty sure it is not ISP issue. I am using cable and I can get 30Mbps.
A good thing that works without root:Youtube HD Mod

I even once had this working perfectly on my Sony NSZ-GS7!
It works without needing anything else,just sideload using any preferred method and you get access to 1080P!
Just adjust the extra settings to gain access to the 1080P resolution.

Define "works" when you cannot log in to use your subscriptions. This whole Youtube /Amazon BS is irritating: somehow I can't even install the "blue" Youtube app...FireTube works fine...go figure.
Almost like they're hell-bent to drive us crazy.
I only used the YouTube HD Mod without subscriptions.
UC Web Browser works amazingly with the desktop YouTube videos.
I watched all five of somecallmejonny's Sonic hack showcase videos with almost zero issues. (YouTube error once)

Youtube - what is the browser maximum resolution for video playback

I have tried a few browsers and 720p is the highest i can play without the audio and video going out of sync or the video jumping, by the way it was chrome.
I was asked this question by an future 10.5" buyer who wanted to know if it was possible to play 1440p youtube video`s smoothly.

HD video on MX player

Ok, this is not specifically a Fire app, but just wanted to throw out there that the fire plays everything i've thrown at it - 1080p HD video too in Mx Player, with HW+ decoding, flawlessly.
Mentioning this because amazon's specs say it plays SD video, but the cpu seems very capable, and the screen isn't too bad either. Colors seem to have a bit of a yellow hue instead of pure white, but it's pretty good, especially at the price.
It says it plays SD video since the screen isn't an HD screen. The screen on the Amazon Fire is 1024 x 600, HD is defined as 720p (1,280 × 720 progressive scan) 1080i (1,920 × 1,080 split into two interlaced fields of 540 lines) 1080p (1,920 × 1,080 progressive scan).
The hardware is capable of playing HD content. It just down scales it to fit the native hardware resolution.
How did you get hw+ decoding? My movies are very laggy. Had to switch to software decoding...
go to mx player, settings, use hw+ decoder. I also checked everything in HW+ video codecs

cannot play downloaded youtube 4k videos smoothly with mx player and default player !

hello all... i m facing a strange lag in my htc m9. currently running Viper one m9 4.3.0. but i have tested with stock rom also , that, i cannot play 4k videos smoothly which i'have downloaded from youtube. i moved that video to my device memory, then opened it with mx player. that video is only playable with mx's SW mode but veryyyyy slowly. both the HW/HW+ mode says "not supported" what can i do to play those 4k videos smoothly in my device? please..T.I.A.
The M9 have an 1080p display, so 4k videos, even 2k videos won't look better than 1080p videos...
You can download the videos at full hd resolution from youtube, you will save space too.
The problem is mxplayer. Because it is downscaling the video from 4k to 1080p on the fly via software it can only convert so much in so little time and that causes it to pause while it converts.
You will find that youtube servers do the bitrate at their end so even if the video says 4k, if you play it via the YouTube app you'll only get the max resolution that your device can handle, in this case 1080p as that is all your device can do.
