Finally! I can't tell you how many videos I've watched on YouTube where the video isn't "full screen" -- it's a 16:9 aspect ratio, but it surrounds my monitor in a black box because it was uploaded as a letterboxed 4:3. This extension is exactly what I needed. Thank you so much!

This just doesn't even work. I've uninstalled and reinstalled many times, but it doesn't do anything.

It is currently broken, setting it to 21:9 while in fullscreen only stretches the YouTube video horizontally. This is also happening with other extensions, "Zoom to Fill - Ultrawide Video" and "Aspect Ratio 21:9". Maybe YouTube is the culprit here? edit 26/1/21: Was able to determine something was wrong with my machine. Disabled hardware acceleration in chrome. Works perfectly but I am dropping frames on YouTube. Another problem to solve!

So many options but none works 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...

Extremely horrible, unfriendly user interface, will break your video playback and cause audio issues. Hope improvements will make this even remotely usable because this does address a big problem with automatic aspect ratio adjustment.

어떻게 활성화하는지 아직도 의문이지만. 어쩌다 보니 작동이 되기 시작했고. 그 뒤로는 막힘 없이 된다.

Works flawlessly on all sites, but Disney+... It even works on streaming sites and adjusts automatically for when it detects that there are black bars. If it could work on Disney+ too that woulf be great. I currently have to force 21:9 on Disney+ with this other extention(https://chrome.google.com/webstore/detail/disney-plus-ultrawide-ful/pdnmlnhalemfcehgdnfkpehgoniobnph) and blacklist disney+ with this extention. (btw the fact that this extention can blasklist sistes is amazing)

Amazing and exactly what i needed. Scales Netflix, Stan, Disney+ etc.. You lose next to nothing scaling 16:9 to 21:9 but the experience of ultrawide is absolutely the future. Can't go back, won't go back. Well done dev!
