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.
