How do you resize the video?
Plex Web doesnât have a function to resize the video to fit the screen. Looks like your video has embedded the black bars to the top and bottom. Better if you re-rip/encode that file.
Iâm using plex for windows and the video is a just a remux of a bluray disk. To remove the blackbars I would need to reencode the original and in doing so lose quality. Seems like such a basic feature to have on a video player.
Why would you want to stretch the video? It looks like you are seeing the video in the exact aspect ratio it was filmed in. It seems that it should be viewed as it was filmed.

If you want to stretch/slice/dice/etc the aspect ratio, use Plex Media Player, PMP. Download from the Announcement thread.
To set aspect ratio, change into TV Mode (in upper right, click on box with âTVâ inside).
Select your username â settings â video â video aspect.
Youâll have to use arrow keys for some navigation.
See support docs linked below for more details.
FYI, PMP can also passthrough audio, if youâve a multi-channel sound system.
To change back to Desktop Mode (looks similar to Plex Web) from TV Mode, select the computer/NAS icon (where TV icon was before). No idea if aspect ratio changes are honored in Desktop Mode. Pretty sure audio passthrough settings are honored in desktop mode.

I donât want to stretch it, I want to crop away the black bars and keep the same aspect ratio.
The movie was recorded in 2.35:1 and then for the bluray release they add blackbars to make it 16:9.
Thanks dude!
2.35:1 wonât fit a 16:9 display.
If you want your eyeballs to see what The Director wanted you to see on the edges of the frame - ur gonna have to incorporate some black bars or the math just wonât work out.
If you have issues with black bars - youâll have to sacrifice aspect ratio integrity - in favor of satisfying that pesky itch you just canât seem to get scratched.
Turn down the lights until the bars blend in with the Display Case.
Youâll never notice them.
If you watch nothing but bars - youâll never see any of the actual material.
So instead of cropping you want to chop away the the left and right parts of the video. The video was 2.35:1 which will not fill a 16:9 screen. In terms that compare apples to apples 16:9 equals approximately 1.778/1. If you remove the black bars what would you replace them with? If you replace them with nothing and want to keep the same aspect ratio then you either chop off a good bit of the left and right of the picture or you allow Plex or the display device to fill the space with their own black bars. It seems to me that black bar = black bar.
A 2.35:1 movie is wider than a 16:9 movie.
If youâre using a 16:9 screen (HDTV, etc), to show the full width of a 2.35:1 movie, there must be bars at top and bottom. If you have no bars then the sides of the movie are cut off.
Draw a 16:9 box. Now put a 2.35:1 box of the same width inside. It will not be as tall.
Guys I have a 21:9 display and not a 16:9, I thought that was obvious with the screenshot being 3440x1440.
Yeah I found it, thanks for the help 
looks much better now. And I can deal with blackbars on either the sides or the top/bottom depending on the movie. But having them all around the movie was kinda pointless
Screenshots are not a reliable way to see what the display device actually is. What you have is so rare that you cannot expect Plex to support it in any reasonable way. To make the source fit your display, if the original Blue Ray does not have a the ability to do it you will either need to use something like Handbrake to crop the video or you will need to use a video processor in route to your TV to accomplish the same thing.
There are a number of video processing devices that sit inline and crop, stretch or otherwise alter the video on the fly. There is a problem with that in that it takes time to alter the video and the video processor must delay the audio so that it will correctly maintain sync. The only video processors that do that well are quite expensive but they are out there.
Of course I can expect Plex to support it, itâs been supported on almost every single video player since 2001.
Who among us, with eyeballs with as much mileage as mine, can make out the edge of something dark in the dark?..lol
Yea, I see now⊠apologies for calling you an Aspect Ratio MurdererâŠ
Yeah itâs fine, I should have picked a better and brighter scene to printscreen 
And yeah I would never change the aspect ratio, thatâs the same kind of crazy as not removing the information stickers you sometimes get on your TV.

Itâs my âLight Meterâ - when I can see it, there are too many lights onâŠlol
I also have an ultrawide display. I see thereâs aspect ratio options on the âTV Layoutâ mode. How can I have Plex completely fill my ultrawide display with 21:9 movies when not using âTV Layoutâ in PMP? I am fine manually switching with the Z key as how it works in the tv layout mode, but I am not interested in using that mode right now due to how much of a slog it is to navigate with a mouse. Obviously the UI designers at Plex HAVE left us a way to view 21:9 movies in fullscreen on ultrawide screens in the desktop interface, right?
You just need to go into TV layout mode to change the setting, after that you can switch back and the setting will still apply.
