    I know the iPhone xr has a display with a resolution slightly higher than 720p ; in really curious , which is the max resolution that the YouTube app supports ? Does it support 1080p ? I know the xr's display won't be able to display it natively , but the higher the resolution of the videos you play on YouTube , the better quality you get , just because of less compression .

    Thanks for your answers

    YouTube supports video up to 4k. It doesn't matter if you click on a video and try and set it to 1080p, you won't see such on the XR, and it won't make for less standard YouTube compression.

    Does anybody know if the YouTube app for the XR needs to be updated to fit the phone resolution for scaling?
    I came directly from a Galaxy S8 and noticed that YouTube video quality is noticeably worse on the XR at the same video resolution as the S8. Hopefully this gets addressed it's a bit disappointing. The rest of the screen performance in other apps is really good it's just YouTube for me.

    YouTube for the XS Max still hasn’t been updated from the X’s 2436 X 1125 resolution. It’s driving me nuts!

    Will the XS Max play 2208 X 1242 and then downscale to 1080P? I’m assuming the XR will play 1080P and then downscale to 828P?

    You can set it to any resolution you want but it will only play at 720p. The resolution is higher than 720p but not 1080p so that's where it will play. Non issue to me since I always watch in 480p. Looks good enough for a 6" screen and saves on data.

    I think it will upscale/downscale, like iPhones do today.

    Again, this is not true. It will play 1080p videos.

    How is it not true? It will play 1080p downscaled to 720p. How can it play videos at a resolution beyond its capabilities?

    You can select 1080p but it will downscale to the native resolution of the Xr which is 828p.

    Wrong. It doesn't downscale to 720p.

    The XR downscales to 720p60. I just did it.

    It still looks really good.

    720p will get upscaled to 828p.
    1080p will get downscaled to 828p.

    So selecting 1080p should look better since the XR is higher than 720p.

    You are really not getting it. The max resolution is 828p. How is it going to play something at a higher resolution that it is capable of? It is going to downscale anything higher than its max resolution. You can click 1080p or even 2160p all day long. But it isn't playing at that resolution.

    YT technically tells you 720p60 as it doesn’t have an option for 828. I agree we are likely seeing 828 on XR. I’m really enjoying this XR.. it’s trying to send my XS back to the Apple Store.

    Not sure if it's 720p or 828p. Which most people couldn't tell the difference between anyway. But it's sure not 1080p like this guy seems to think he knows it is.

    It gets downscale to the native resolution of the screen. It can’t natively display 1080p it can only downscale the resolution to 828p.

    It depends on if the app is optimized I believe. Both the XS Max and XR have the same "point" mapping of 414pt x 896pt. From there the image is rasterized, 3x for the Max and 2x for the XR.

    Pretty sure the XR will render in 1080p then rasterize, downsample and display at 828p.

    In the case of the XS Max, render in 1080P, rastersize, upscale and then display at 1242P?

    Again, I think it all depends on optimization. For video specifically, the XS Max, if the app is optimized, might skip the rasterization step and go straight to 1080p and upscaling to 1242p.

    IMO, either way, 300+ PPI/DPI, your eyeballs just can't resolve the difference, no matter what you might believe. Don't even get me started in the difference betwen RGB subpixels and OLED diamond pentile.

    Nevermind - rasterisation would only be for text and other UI elements, not for video. It would render in 1080p then downscale to native res (or upscale).

    Ok last post. Interesting reading material - https://oleb.net/blog/2014/11/iphone-6-plus-screen/

    You aren't getting it. It isn't playing it at 720p

    Exactly, which isn't 720p as he said.
