    Just got the Apple TV 4k and hooked it up to my Samsung new oled65c7p. I notice in many of the netflix's 4k shows there is a lot of what looks like film grain/noise. Some shows are not as bad. I tried several 4k UHD youtube videos on the built in 4k youtube app on the tv and no grain at all (and was blown away).

    Im assuming the grain is in the original filming wether it be high ISO noise or just film grain and then the 4K HD makes it more obvious?

    I'm assuming you mean LG OLED. Samsung doesn't make OLED TVs. Yes, depending on what you are watching there's a lot of film grain in older films. But that's not really a 4K Issue. It's an issue with how a film was originally shot and how old it is. 4K won't change that unless it's a fully remastered film.

    Yes meant LG. I notice the grain on even Netflix 4K shows such as Santa Clarita meal etc.

    Can I ask, since the lg TV has web is 3.5 with apps for Netflix etc, what made you buy the apple TV 4k? Is the lg os clunky or is there more to it than that?

    Good question. The lg is great and I’m using it for most everything. I’m an Apple guy so just wanted the ATV for the ecosystem but will prob use the lg apps more since I use Netflix, amazon, YouTube etc. the 4K uhd 60fps material on YouTube just look amazing.

    Should I bother with an UltraHD blue ray player?

    The lg os is pretty good actually. But I use a separate streaming box so I can run it through my receiver for the good audio.

    I use the optical out from my tv to denon 730 and it sounds great and handles all the surround formats.

    Nope. Best you can do over optical is Dolby Digital/DTS. So 2 surround formats.

    You lose out on Dolby Digital+, both lossy and lossless atmos, Dolby TrueHD, DTS-MA HD and DTS:X

    Interesting. Sounds better then my Apple TV. I don’t think the Apple TV handles all those formats? Does the streaming box do all the 4k hdr Dolby Vision 4K YouTube
    etc? I just have a Klipsch 5.1 system and it’s in a bedroom so I don’t need all the atmos etc. what’s box are you using

    I'm using an Nvidia shield for my movies. Netflix and amazon as well. The youtube app is much better on it.

    For streaming everything else I use the appletv.

    I’d strongly recommend the LGs built in apps over the shield tv and Apple TV apps. The LG apps will play material at native frame rate whereas the shield is locked at 60fps for Netflix for example. The op has a latest generation LG Oled so the native YouTube app will display 4k HDR. The shield and Apple TV apps can’t do this. Also, I’m sure the new LG Oled’s can output Atmos over hdmi arc. It can’t do HD audio but none of the streaming services manage this either. I can’t think of any benefits from using the streaming apps on the shield or the Apple TV. Only negatives by comparison.

    That being said, I own both a shield tv and Apple TV 4k. I use the shield TV for Kodi and the Apple TV 4k for 4k iTunes films.

    Same here. I have a samsung ks9505. Smart tv app looks better.

    Wonder what this is? But tv os 11.0 has allot of bugs in regard of quality, subs falling out etc.

    Indeed. Netflix on the apple tv, is (besides the jumping streaming quality) less sharp, than the built in one..

    This basically means, i only use my apple tv for renting or buying movies in HDR.. sigh..

    Apple said they're working on the SDR -> HDR conversion algorithm - I hope they're also working on the 1080->4k up scaling

    You can change the framerate on the shield. If you want 24p just set the shield to that. Plex will auto switch. Though Netflix on the TV and on the shield look identical to me. Youtube HDR is kinda pointless. Really just for some HDR demos. A handful of scenery videos on the HDR channel. If you really want that you could switch to the TV app but the vast majority of the time you wouldn't need to. They can do atmos over ARC, but can his receiver handle Atmos via ARC? I'm guessing since he's using optical his receiver doesn't support ARC at all. And you're certainly not getting DD+ at the very least.
    HD audio is primarily for local content.

    The real question is what audio does it support over ARC? It's certainly preferable to use ARC over optical.

    The monitor out on the denon says hdmi/arc and the in on the tv says arc and I recall seeing a menu option on the denon to enable arc. So does this mean it should handle arc? I’ll have to try it when I get home tonight and will also be replacing all my cables with premium certified hdmi cables as the ones I have no don’t handle Dolby Vision from he Apple TV.

    Yes, ARC will work. You use those ports and enable it both on the TV and receiver.
    You can get the cables cheap on monoprice. I have several from there including one 25' cable. All work great!

    Dont worry, nothing wrong with your tv! We're all beeing swindled again. By apple and Netflix. They present "4K movies" wich never been shot in 4K. Like the early days of CD's. The copied a LP or even a music caset to a cd and called it DIGITAL.

    Netflix 4K shows like those from Marvel have massive amounts of grain, it is just the way they are done. And in HDR, the brighter areas really show the grain.

    I also have an LG OLED 65. A few months ago, an LG update wiped out the YouTube app on my LG. And of course, we're still waiting for the Amazon Prime app to be available on the new ATV 4K box. While my eyesight is not the best, NetFlix appears clearer to me via my LG NetFlix app verses NetFlix via my ATV 4K box. Wondering if that's going to be true when Apple gets around to the Amazon app on the ATV 4K?

    Thanks. Yes the mono price are the ones I ordered from amazon. The Comcast cables said 4K high speed etc but didn’t allow the atv to work in Dolby Vision.

    Any apps or shows on the lg tv app that I can use to test the atmos etc once I set up the arc vs optical?
