iOS and iPad are limited to a maximum of 480p

iPhone 13 pro max, the server is the latest version, and plex for ios is also the latest version, but when using traffic, it is limited to 480p and cannot display higher resolutions.iPhone has been upgraded to the latest 17.1。When switching to wifi, all available resolutions and bit rates are immediately displayed

Did you setup a remote bandwidth or quality restriction on your server or the iOS Plex settings?

Already set to maximum, traffic limits and automatic quality are cancelled.

What about the „physical“ upload bandwidth limit (I.e. your ISP‘s internet upload speed for the network connection hosting you server?

No problem, about 100Mbps, 12M/s

[tom80H]

If your upstream connection is only 12 Mbps, that explains why Plex is only offering you remote quality options up to 1080p @ 8.5 Mbps (keep in mind that the max bitrate of a video can be significantly higher than the average).

Thanks for the answer. It is not 12Mbps, but 100Mbps. The speed is about 12M/s. However, it is not a bandwidth problem. Even if I increase the bandwidth to 1000M in the settings, it still only displays 480p on iOS. On the contrary, when I tested on Android, even if I lowered the bandwidth to 1M in the settings, all options were still displayed. Obviously this is a problem with the ios app.

iOS Plex app won't give transcode options above 480p

Bug Report: Transcoding capped at 2Mbps / 480p on iOS app

Thanks for sharing. I can see the same when using the playback quality settings during playback (independent if it’s a local or remote stream) Edit: Correcting my initial response. I was only seeing the limited playback quality options when streaming locally because I used a lower-quality video to test (DVD quality, so the 2 Mbps@480p was simply the “next best” transcoding target). With higher quality files, I also get to see the higher playback quality options while streaming locally. I do…

In fact this issue was brought up last year and you responded that you got the same situation. And this seems to only exist on iOS, Android doesn’t have this problem. This is obviously a bug and hopefully Plex will fix this.

The situation is that when using mobile network, you can play back using the original quality, and if you want to transcode the playback, the highest option for transcoding is only 480P. There is no such limitation when using a WIFI remote. Mobile network can play back the original quality properly, it must have the ability to play back quality higher than 480P, but it’s still limited.

In China, our traffic is unlimited, so we don’t have to worry about exceeding the traffic limit. I hope the official can consider our actual usage environment and relax the maximum 480p limit.
