Description from extension meta

The cross-browser extension that manipulates video aspect ratio to fit your entire screen.

Image from store UltraWideo
Description from store 👋 Introduction The only extension on the market with two significant functionalities that no other extension in this category possess.
 ▸ Works on all video streaming platforms ✅ ▸ Works on all embedded videos ✅ It doesn't matter if there are multiple direct or embedded video players on a single page. The extension is smart enough to manipulate the video you put into a fullscreen, without affecting other video players. 🤷‍♂️ Should you use it? It's for everyone who wants power over the video aspect ratio. This extension is primarily for UltraWide monitors, but that does not mean it's only good for it. You can manipulate the video's size that contains horizontal or vertical black bars and let the video fill your entire screen for a better experience. 🚀 How to use it? The extension is relatively easy to use but very powerful at what it does. It has a couple of options: ▸ Pause the extension – It will stop listening for all memory consuming events and restore any DOM manipulations.

 ▸ Toggle between modes – Toggle between different options will affect the video: normal, upscale, and stretch.
 ▸ Configurable shortcuts – Set desired keystroke, with min/max of 3 keys to control pause or mode toggling. 🤞 Works everywhere? It is working on all globally popular video streaming platforms. Making a list of all platforms would be very expensive and time-consuming since many platforms are subscription-based.

  • (2021-07-12) Ʀ: perfect <3
  • (2021-07-09) JOSEGRICHE 18: It worked perfectly in all platforms :)
  • (2021-07-09) Steve Jossi: This app works in some places and not others. Currently I'm experiencing an issue where both upscale AND stretch only stretch horizontally, not vertically. So the image stretches sideways and doesn't actually work. Please let me know if you need any additional information to fix this issue or if you can help me troubleshoot.
  • (2021-07-08) auguit: Works perfectly, thanks for awesome extension!!
  • (2021-06-29) Kreativni Blok: Best one.
  • (2021-06-12) O T: Works perfect, provides the option to either zoom in or stretch out the content. 10/10 would recommend.
  • (2021-06-06) Dominik Kowalski: I like it. I have 4k monitor, black borders where annoying me for 2 or 3 years but with this plugin I can finally use ''real full screen mode''. Its also great that it works with any video players (Netflix, twitch, YouTube ...etc)
  • (2021-06-02) Danny Aldana Hidayat: Works well for me, thanks!
  • (2021-05-23) Diego FC: Just stretches the picture, "upscale" mode not working.
  • (2021-05-02) TONY LARIOS: Great app but hard to find in Edge Chromium. The only main problem is that in Chrome the switch modes don't apply realtime as when using this app in Firefox, I always have to restart the browser. One addition I's like this app to have is to have modes for more aspect ratios.

  • (2021-01-28) Tavinhoo!: funciona perfeitamente na netflix
  • (2021-01-23) Xavier WINGLARZ: It doesn't work on a 3440x1440 monitor on YouTube so it's pointless. Ultrawide video was working perfectly (CTRL+ALT+C shortcut, very simple) but was removed, I'm trying to find another one which works but for now, none of them are...

  • (2020-08-17) Chirag Gandhi: This the best one ever! You did an amazing job!
  • (2020-08-12) Dillon: This does what is needed for my 21:9 ultrawide when watching clips on youtube that are squished. The problem is that if the video is a regular 16:9 it crops. There was an extension long ago that could automatically distinguish the 2 and you could leave it on forever but due to changes on my end or chrome's I have never found another app that did this successfully. So the problem is I have to manually turn on or off for individual videos.
  • (2020-08-12) Jeremy: Finally an app that lets me utilize my ultra wide monitor.
  • (2020-08-09) MiniOr4ax: didn't work at all
  • (2020-08-06) Trey Polhemus: Works as it says. Perfect video output on my 34" ultrwide (21:9). Thank you for the great extension!

Latest issues

  • (2021-01-28, v:2.4.0) Nick De Villiers: "Upscale" now stretches
    I love this extension but it's become unusable now, the "Upscale" button now just stretches video for me rather than actually upscaling, so I'm forced to just grin and bear it with the baked-in black bars. Hope this can be fixed soon since this is a really essential feature and the extension isn't even worth having without it.
  • (2021-01-13, v:2.3.0) Gonza Job: Stretch mode
    Hi, stretching just does that, stretch. Fits the image as is, into the viewport. Can you please add an option for anamorphic stretching to reduce the massive distortion of the image at the center of large wide monitors? Thanks. I love the extension.
  • (2021-01-09, v:2.2.0) Thomas Förmer-Biedermann: stretchmode
    if I use the toggle key (e.g. strg + shift + 9 ) for stretching the video stretches only at the right side of the screen. on the left side the black box stays.
  • (2020-01-14, v:2.0.2) Jacob: 32:9
    Please add 32:9 aspect ratio support!
  • (2019-05-04, v:2.0.1) Patrik Kleveland: seem to create audio sync problems
