Should i use 4K HDR/DV in the settings over SDR? Any benefits or downside to using one or the other? My tv does support both.
 
Use the maximum setting 4K HDR and chroma 4.2.2 if your TV supports them. if you want to downscale to 1080, you might have saved money and got the HD instead. You can test between HDR and SDR to find out what suits your preference. I would use HDR because I did not spend $$$ to upgrade to 4K HDR TV to watch 1080p contents.
 
Apple TV 4K doesn't look good with HDR turned on. Turning it on fakes HDR and end up making things worse for the most part (screen saver is one of few exceptions).

Set it to 4K SDR instead, but turn on Match Dynamic Range and Match Frame Rate.
 
Sorry for hijacking this thread, but: Is there any upside for having a ATV 4K on an 1080p display when it comes to games or general performance?
 
Huh? ATV4k with the right HDR material is spectacular.
I said HDR turned on.

It looks great with HDR materials, but turning on the HDR setting messes things up. Just use match dynamic range setting instead.
 
I have mine set at 4K HDR 4.2.2 60hz but with dynamic range and frame rate matched. This way it does not try to convert SDR content into HDR. This setup works best for me.

nutmeg is referring to how the Home Screen and other general areas and apps look with HDR/DV on, not the content. I leave mine with DV on as I actually prefer the Home Screen that way. The SDR screen looks too dull to me.

which is exactly what they said

SDR material that is "upscaled" to HDR doesn't look good, But HDR material looks great.

By leaving the aTV in SDR mode, but range matching on. you get the best look for the menus, and still get HDR for the content that needs it.

the main reason I leave mine in SDR (with matching) is my TV blacks out when changing video signal types, for the HDR to SDR switch (either way) it takes about. 2 seconds to come back, since most of my stuff is SDR, that switch happens much less often
plus I prefer the look of the menu screens in SDR

The only downside to using SDR setting is the screensaver, which looks better (at least to my eyes) in HDR setting. But by using "match dynamic range", you are guaranteed to always get HDR if the source is HDR, while SDR will be rendered in SDR instead of "faked HDR".

I'm clearly missing something. My format is set to 4K Dolby Vision 60 Hz with Match Dynamic Range and Frame Rate off. Have no issues with upscaled content (via Infuse or Plex), home screen, or anything else ....

How you have set it up SDR content gets converted to HDR (fake HDR). While the difference to SDR isn’t huge it still is not optimal. There’s a good vid about this:
It is best to turn on Match Dynamic Range and Match Frame Rate for this reason (so that SDR content gets displayed as SDR).

I hear this misinformation over and over here and everywhere else on the internet.
You do realise match dynamic range is a two way street. It doesn’t just convert from SDR to HDR/DV, it does it the other way too.
Think about it, it’s MATCH dynamic range. It will match the dynamic range of whatever is being played at the time, whether that is HDR/DV or SD (so long as the app being used supports it).

The whole interface and screensavers etc look a whole lot better when I’m using DV on.
If you prefer the look of the interface in SDR, fine, carry on.

No, I do not prefer the SDR look of the interface/screensavers. That is the reason I have my Apple TV 4k set up as 4K + Dolby Vision.

But I have Match Dynamic Range on because this way HDR content gets displayed as HDR and SDR content gets displayed as SDR. Otherwise (if you have Match Dynamic Range off), SDR will get the fake HDR treatment as mentioned in the video.

My bad, I thought he was saying he has match dynamic range on but match frame rate off.
Yours is set up the same way as mine, Dolby Vision on, match dynamic range and frame rate.
I see so many people saying that the only way an Apple TV 4K should be set up is SDR 50/60, match dynamic range and frame rate.
There is absolutely no reason to set it as SDR if the matching is on, unless you don’t like the appearance of the interface, or you have an app that doesn’t follow the matching rules.

Think I figured out why I'm not seeing problems with SDR/HDR upscaling. My Apple TV is not connected to my TV, but to an Oppo 205 which connects to the TV. I think that the latter is doing all of the conversions, rather than the Apple TV. Can't confirm though.

I haven't tried this, but generally (for menus and such) like the look of 4K SDR better. So if I put matching on for HDR content, it will switch just for the content that is 4K HDR and then back to SDR for everything else? Is it seamless or does it flash the screen black and switch?

That will depend on your TV.

and also on what's changing on the signal

for a frame rate change, mine is pretty quick, for a range change, it's a bit longer
it's maybe 2 seconds at the very worst though.
