I have the below file. It is listing it as 720p, though the resolution is 1920x704, which is 1080p.
Running PMS version 0.9.16.0.
1080 is 1920x1080 (if it’s a true 16:9 aspect ratio). 720 is 1280x720 (for 16:9). And your file only has 704 vertical lines of resolution, but it’s wider than 16:9. It’s the vertical lines that you use to determine a label for resolution IIRC. Yours certainly sounds like 720 to me (close to it, anyway), just like Plex said.
OAR is 2.75:1. That’s why the height is so short.

This isn’t actually true. 720p denotes a standard 1280x720p resolution by listing only the standards trailing number as an abbreviation; while 1920x1080p would list as 1080p.
The leading number should really be used to determine the resolution, as videos often have the vertical cropped to remove the black bars; which are added to ensure they fit the standard, but aren’t needed in most cases.
Note: The ‘p’ is generally no longer needed either, as ‘interlaced’ digital videos are so rare it only really makes sense to denote the ‘i’ when appropriate, but not the ‘p’.
You might also note that 4k and 8k are actually referencing the leading number in the resolution, not the trailing number. So 720p is actually better listed as 1k, and 1080p as 2k, with the leading number being standard and the trailing number varying dramatically based on aspect ratio.
PLEX should know all this, they are professionals. But I just noticed a movie in my collection listed as 720p for both the 1920x768 & 1280x512 versions!
If the 768 lists as 720p, why doesn’t the 512 list as 480p?
I am disappointed to see that this thread ended on that note. @rkoegel makes at least four separate points in this last post that should be obvious to anyone who knows anything about digital video and the way we interact with it as consumers.
I’m waking this thread from the dead because I was hoping for more!
I came here wondering why a particular MKV file (1836x800) is being labeled as 720p by Plex. HandBrake simply modified the dimensions (removal of letterbox bars) of this video file automatically as I was encoding this file to HEVC, as an additional step to reduce output file size. In this instance, the file is being played locally on the Nvidia Shield TV, which is also the server. Latest updates.
The file has (roughly) a 2.39:1 aspect ratio, which is very common.
Yes, 800 is closer to 720 than 1080, but that’s not the point, is it? People realistically use the 720/1080 specs to set pixel density / volume expectations.
A 720p video with true 1280x720 dimensions only contains a pixel count of 921,600.
The total pixel count for my video is 1,468,800. That’s 59% more pixels than standard 720p. So the real question is…what useful information is Plex providing me by telling me the video is 720p?
Also, this file contains a Dolby Atmos audio track, which Plex is identifying as Dolby TrueHD - I know exactly why that is - but to say this file is a 720p TrueHD item, when it is actually a 1080p Atmos item… So far off the mark it’s just crazy.

I’m also going to bump this thread as I came to it via a search. I have a video file of 1856x1004 which is showing as 720p. I was looking for a way to manually change the resolution to move it to the 1080p category but I couldn’t find a way. I appreciate that PLEX automatically collects the resolution of all my files, but I don’t like that it can make errors and allows no way to fix it. Thanks…
