Works perfectly with my 4:3

Wonderful addon for those of us with a secondary or primary CRT monitor, since a lot of people forget to encode youtube uploads in 4:3 even if they contain no data outside that resolution.

My only request would be to allow it on a per-tab basis or restrict it to certain aspect ratios, since my primary monitor is ultrawide and I'd have to disable it manually every time I wanted to switch monitors. It looks like that's a work in progress for the pro version, but I'm not sure. Excellent addon nonetheless. It works instantly and flawlessly.

Ive been using Ultrawidify for long, but it has major performance issues with 4k 60fps ultrawide (on very powerful hardware you will have 1% frame drops with it enabled). This extension is far slicker, lower footprint, does not cause ANY issues with the same footage, and it offers a very convenient way of adapting a quite troubled aspect ratio of superultrawide 5120x1440 32:9 to the needs of the user. It must be said that 5120x1440 32:9 is basically a failed concept of aspect ratio implementation on a monitor that is supposed to play content NOT natively made in that same format. It will NEVER work properly fullscreen without cropping or distortion. This resolution should have received a 32:10 monitor solution. Sadly cheaping out on the panel size made it a sad affair for scaling video content. The solution for me is to set X to 0:9 and Y 1.3 in stretch mode.This will have small horizontal black bars but they are a acceptable trade off , minimal cropping the content,and have a natural viewing experience with no distortion.
Alternatively setting it to NORMAL with X at 1.9 and Y at 1 will not crop anything, while having minimal black bars vertically.

Conclusion. No software solution can provide the perfect 32:9 5120x1440 experience. It is inherently a unbypassable hardware problem to display content not natively provided in that format. A video game that offers the resolution settings does this. A video not recorded in that same format can not, no upscaling or stretching can remedy this to perfection.


What i do not like is the paywall for pro features, at least name a price and the added functionality in your UI.

Thank you for this extension! I can watch full screen on my 4:3 TV

Works perfect on YT 21:9, Thank you!

works great
