FYI... for those of you that want to calibrate your TV for the Shield's output, Spectracal just released a very cool free piece of software.

http://calman.spectracal.com/mobileforge.html

Just Google Cast it to the Shield and connect the app over wifi to a running instance of Calman on a computer and it will automatically put up the correct test pattern for the different parts of the calibration process. Saves a ton of time and you don't need a separate test pattern generator.

Obviously you have to be a Calman software owner with a meter to do this.

I got the shield running the latest build, but is there any issue with Samsung and refresh rate switching?

I have UE65HU8500 series from Samsung and I am using MHL 2.2 (HDMI4) port on my One connect.

I have downloaded the TVHz app from AppStore. When I use 4K I only got 60hz available .

If I use my switch and 1080p I got 24,50 and 60 hz.

Any tip?

4k switching does not work at the moment for me either.
Aparantly its work in progress with Nvidia.
So for now I leave my Shield at 1080p and change ports when I need to see 4k content.

Is it possible to force the Nvidia to output 1080p? I think all of inputs supports 4k

It supports up to 60fps playback.
You dont need special hardware to playback slower frame rate as that needs LESS power.

That's not how it works.

[Tinwarble]

It's not a matter of what the hardware supports. It's a matter of what the OS (Android) supports.

You don't need specific hardware to support 23.976 either, the limitation is in the OS.

Now, I don't have 4K. But the specs do state AT 60 fps not up to 60 fps.

Android DOES support it.
Other Android boxes that can output 4k let you choose 4k 30 or 24 etc.
And we got TvHz app that was made for nexus player that lets you manually choose refresh rates.
Nvidia just needs the firmware to do that.

What good is a 4k media player that cant do 24hz!

[Ned Scott]

Actually, that's not true. The ability to do something at 60Hz doesn't mean it can necessarily do 24, for example. It involves multipliers and clocks and magic black smoke, and a bunch of other stuff that I honestly don't understand. However, I can tell you that almost all Android boxes can output 60hz, but not all can output 24hz.

Keep in mind, I'm only speaking generally. I have no idea what the actual refresh rate options are for the Shield TV, so it's probably a moot point for this discussion.

[Martijn]

What good is a 4k media player that cant do 24hz!

Let's make one thing clear. The SHIELD was never designed to be a media player. It's a game console as primary target and additionally it plays media quite well.

And that's what I meant anyway. I wasn't speaking in general terms, I was speaking about Android on the Shield.

This is the Shield thread after all.

Maybe it possible in the future to have 50hz and 24hz output with 4K on nvidia Shield!
Hope so!

But is it possible to force the Shield to output 1080p?

All of my input auto choose 2160p! And since I use Kodi for Live TV (50 hz, Norway) and 24hz for movies I cant use 4K output.

Try using hdmi 1.4 port on tv and selecting Best Framerate in Shield settings. That should choose 1080 60 as hdmi 1.4 only supports 4k 30.

[dbourgoyne]

Can Kodi, or any Android application on Nvidia Shield Android TV, play 4K video and maintain 4K resolution all the way to the TV? I think the video is being scaled down from 4K to 1080p and back up to 4K. See "dumpsys SurfaceFlinger" below. This was done while Kodi was playing a H.265 2160p60 video file. Notice the Display [0] configuration is 1080p60. Also notice that HWC is scaling the 2160p output from Kodi to 1080p and that the HWC_FRAMEBUFFER_TARGET is 1080p. I have a 4K Samsung TV model number UN40HU6950F. The Shield is connected to HDMI port 3 which supports HDCP 2.2. The Samsung TV shows that it is receiving 2160p60 video.

Is the Shield decoding 4K, scaling the decode texture to 1080p for hardware compositing and then scaling back up to 4K before sending over HDMI? That's what the SurfaceFlinger dump suggests.
