When you set up the Apple TV, if it says that your TV is 60HZ SDR, then the picture settings should be 4K 60 HZ SDR.

I dont have a new ATV, but i've seen a lot of the detailed reviews - is your video output on the ATV set to match the above.

I am not sure what relevance the cable is? 

Maybe i'm confused, but i thought the Apple TV setup process determined the capability of your TV, not just the cable.

Anyway, assuming you have a Netflix 4K subscription, if everything is setup ok, you should be able to see some 4K content (the app detects the TV capability). Have you tried this? If you have the 4K subscription and no 4K is showing on Netflix, then something is wrong with the settings.

In the end though, from my experience with an Avant Mk1, streamed 4K is not that much better than HD - so i wouldn't necessarily expect a striking difference. I use 4K streams from Netflix and Amazon Prime on my Avant Mk1 - its very ice, but noting special.

Perfect Info thanks a lot:

it says Input 3840x2160p 

Output Display res 1920x1080p

So... only Full hd ?

I also have the same Output display resolution (1920x1080) on the Avant Mk 1 when viewing 4k content via my Roku Premier+.  

Why is the Avant Mk 1 not providing 3840 x 2160 output resolution when receiving the 3840 x 2160 input signal?

I believe the output in the service menu is referring to what is output by the menu system ( remember that this is the service menu and isn’t necessarily made for our eyes).  The Avant MK1 using the Beosystem 4s 1080P video processing and menu system and then offloads 4k signals to a custom build FPGA that handles the 4k signal, and mixes that with the 1080P menu system.  Long story short, if your service menu says 3840x2160P as the input signal, your TV is displaying 4k.

Frankly I’ve been having difficultly seeing a big noticeable improvement with the 4k steams via the 4k Apple TV.  That said, if you do some comparisons, the difference is there (although it’s not as much as I would have expected…I’d even call it subtle).  Also, note that because the 4k Apple displays everything at 4k (i.e, native 4k content is displayed at 4k and 1080p content is upscaled to 4k) it’s hard to tell what the actual source material is.  I also have a 4k Oppo blu-ray player and can definitely say that 4k blu-ray is far superior to streamed 4k content from the 4K Apple TV.

Interesting re the output resolution - i have the same showing with my Fire TV 4K + Avant Mk 1.

And yes, 4K SDR is not a big improvement over Full HD -  the step up comes from HDR.

I was also wondering about the 4K Blu-Ray versus 4K Apple TV (or any stream) comparison. I haven't done a side by side, and was expecting the physical disc to be a good deal better than the streamed version.

I was surprised then by the comparison below, from HD TV Test - its worth watching for those interested, and surprisingly the reviewer / calibrator concluded the Apple TV 4K was much closer to the 4K Blu-Ray than expected. In fact, his conclusion was that most people wouldnt be able to tell the difference.

Anyway, i dont have an HDR tv, but the video test was interesting.

thanks for your answers - so if true, that I "see" 4k than its really a bit disappointing (compared to built in you tube app streaming without 4k) - I just saw some demo videos in store which have been very promising - so might be HDR etc. ....

I decided to buy ATV4k because of the lack of 4k material; Am I right that the Oppo 4k player do NOT support any streaming apps? Oppo would be my first choice but I do not want to buy discs with 4k content - want to be able to use streaming options (Avant Mk1 lacks HVEC as everybody of you know...);

Best Regards Elmar

Yes, as said before, 4K SDR is not much of a improvement over normal HD. 

I have an Avant MK 1 - and because its not HDR, i have no need for an Apple TV 4K (unless you had no streaming box to start with).

I also wouldnt bother with an Oppo, as most of the discs in the future will be 4K HDR. Also i believe the newer Oppo players have less streaming apps supported.

Remember the stuff you are shown in the store is clearly handpicked as the very best 4K content to demo the TV. As an example, the forthcoming Blue Planet II in 4K will look stunning. But it will also look stunning on Blu-ray in HD, too. But you won't see that. They'll show you the 4K version and you'll come away thinking it's stunning and make you realise why you need to buy a 4K TV.

Get home and you realise that regular 4K is only a minor improvement over a very decent HD source. Most reviewers of the Apple TV 4K box have remarked that 4K versions of movies are only a marginal improvement over the HD version.

Think thats true for 4K SDR, whether on the Apple TV or not.

I'm generally with you on the "no great hurry to upgrade to 4K HDR", and am a little sceptical over streaming versus physical, but i would encourage a look at the HD TV test link i posted above. So not sure all the ATV 4K reviews are in the "marginal improvement" camp.

The Apple TV 4K HDR was pretty close to the Blu-Ray 4K HDR, surprisingly.

But yes, 4K SDR versus normal HD is not worth getting excited over - i was watching a 4K (SDR) Netflix stream last night, and it looked very ordinary (admittedly it was a drama with lost of dark scenes, but hey).
