What resolution does the Netflix app offer?

Most high-end cell phones have a WQHD resolution. But I think I've read that the Netflix app only supports a maximum of 1080p (also with the Ultra HD subscription). On the TV e.g. Can you watch Netflix in 4K? But is that also possible on the mobile phone?

It just depends on which subscription you have…

The Ultra HD subscription, of course. If I didn't have it, it's clear that only 1080p is possible…

Naturally…

If you have a 4K mobile phone and the UHD subscription, the quality will also be 4k if the Wi-Fi is good enough.

At least with the content available in 4k.

Oh, I didn't know that. Even with mobile data, or just Wi-Fi?

It should be the same for mobile data, unless you have set something else (if there are such settings).

The resolution is set automatically according to the internet connection and not according to the display.

Does that mean if you have an iPhone 11 pro Max, which in 2020 still has a ridiculous 1080p display and you have a 1 Gbit line, for example, the film and the series will not be streamed in 1080p but in 4K. But then only 1080p can be played back

The (Android) app does not support QHD playback. This is probably due to Netflix itself and not directly to the app. I think the content is not in QHD. It remains FullHD or 4K / UHD.

I don't know whether the app supports 4k. There are currently only a few smartphones with a 4k display.

Since the application case for 4k on Android is almost non-existent, I doubt that you can watch 4k content on a smartphone. You also need one of these devices.

Depends on your device and on the subscription.

But can't the Ultra HD just be calculated down to Quad HD?!

The iPhone 11 Pro is not 1080p, but higher. Whether much higher resolution than e.g. 458ppi (iPhone) with a cell phone still make sense, everyone has to decide for themselves.

In addition, of course, the app must also support it. No matter how good an internet connection and display you can have, if the app streams in 1080p at most, that's how it is.
And as far as I know, the Netflix app for iOS and Android phones can only be used in max. Stream 1080p and HDR.

The iPhone 11 Pro Max (the top model from Apple) has a screen resolution of just 2688 × 1242 pixels at 458 ppi

Yes, I already mentioned that. And not 1080p.
The question is always whether you can still see relevant differences when you go higher or whether it just affects performance and battery life. The eye has a limited power of resolution.

You can of course do it like Samsung and build in a 1440p display, but then downscale the display back to 1080p if you use 120Hz, which is much more relevant than 1080p vs. 1440p, want to have.

1242p is almost no different from 1080p

That's 60% more pixels.

60%?

That's too very, very wrong. There's only 15%!

(2688 * 1242) / (1920 * 1080) = 1.61. So even 61%. A display is 2D

If so, then the vertical pixels are calculated and not the entire number of pixels

No you don't

You only calculate the total number of pixels and not the resolution

But that's what you do when you look at the resolution. Either the total number of pixels or both axes. You can't do anything with just one.
That's why they say 4K has 4 times the resolution of 1080p.

e.g. Here:

Ultra HD (UHD) has a resolution of 3840 × 2160 pixels. That is exactly 4 times as much as HD and 20 times as much as SD. The aspect ratio is still 16: 9.

Or here:

UHD stands for Ultra High Definition (German: "extremely high resolution") and describes a resolution of 3840 x 2160 pixels. That is exactly four times the full HD resolution.
