TabS4 & fake HDR

Navigator

As much as the Tab S4 is a nice looking tablet, the support for HDR is nothing short of pathetic & misleading.

 

HDR is only supported in the official Samsung video player and it's not really HDR. The brightness basically gets cranked up a bit.

 

Compare HDR video on a S8+, S9+ and Note 9 sat next to a Tab S4 and see for yourself. The difference is HUGE.

 

Further to this, every other app that on the previous devices mentioned above that supports HDR (YouTube, Prime, VLC, MX, Netflix) fails to output HDR on the TabS4. 

 

Interestingly Netflix does show the HDR logo before playback, but once again, compare it to other devices with true HDR support & the difference is massive.

 

As much as the TabS4 is a nice piece of hardware, it has some shortcomings. HDR in its current form should not be advertised as it is...because it's not really HDR.

 

Then there's the fact videos on YouTube can't be played above 1080p unless you like to watch videos that jerk around a lot.

 

Im not alone in this, XDA forums has an interesting chat on this same subject.

 

Would be nice for Samsung to comment, but I know that even if they did.....it would be a wasted effort.

You are mistaken. The tablets DOES support HDR. It IS working both in mx player and in vlc media player. And yes it does not work in Youtube. Only in modded version Youtube vanced, where you can change the name of the device. It is your problem Samsung, so solve it....

Sorry hard to fully understand that but I'll try.

 

Are you saying you can get HDR working within YouTube or vanced? If so ellaborate how, as changing device name does not work here.

 

Irrespective of the above, HDR performance is poor. Compare to other Samsung HDR enabled devices side by side and you'll see.

 

Hoping some fixes will come in the Android Pie update.

It is cracked version of youtube. It can override the product name, so youtube app think that you have galaxy s8. It is not the problem in Android. Android 9 will not do anything. There is a list of devices in youtube app, tab s4 is not in it, though it should be.

@ToonTonic Here you are, you can try it https://drive.google.com/open?id=1kPPcO_pOJCIZzm1IpV2xvvw6umKuqrrZ

Just go to settings --> vanced settings --> codec override --> tap on galaxy s8+ (to have hardware HDR)

Really I write about it to google https://support.google.com/youtube/thread/3249775

Nobody answered!!!

I'm amazed it's working for you as following that made zero difference for me.

 

HDR remains broken on Tab S4.

 

Shame as it's a nice device.

@ToonTonic But it really works. Just try it.Screenshot_20190421-182204_YouTube Vanced.jpg

Ok got it too work, but had to restart Tab S4 app. Guess I never tried that step.

 

So it does pull up that HDR is in effect, but I dont think it's really displaying an HDR output. Compare a HDR video side by side on another device and you'll see what I mean.

 

An HDR video looks different on my S10+ & S9+ compared to the Tab S4.

 

One issue I noticed with changing the codec to that of the S8 is that it limits video playback to 1080p.

 

So no more 1440p content.

@ToonTonic 

It is dificult to say if HDR is working. Do you understand what is the key feature of HDR?

It is not DCI p3 color gamut (so another (wider) color space) or 10 bit colors (so more colors, 2^30). The key idea of High dynamic range is the idea of more light emission. 100 nits in SDR and 1000 and more in HDR. Use this youtube hdr test video to check. https://youtu.be/hsbM2c6-9Wg It is actually transferming the colors. So something is working. We cannot be sure that everything is working, of course😥😥😥

I'm very much aware of how HDR works. You can probably see from my device list that I have a few that can output it too.

That said, with HDR on Samsung devices there is a giveaway that its triggered even if there is no notification of an sort that a HDR video is playing.

Basically keep your eye on any text etc in YouTube, or slightly pull down the notification bar.

With HDR playing, the text becomes noticeably brighter and with a slightly warmer hue. This change is immediate and very noticeable.

On the Tab S4, this effect only occurs when playing HDR within the Samsung video app or Plex.

This is all aside to the fact HDR on S8, S9 & S10 all looks FAR more vivid & detailed than it does on the Tab S4.
