Best extension for my 21:9 monitor! Working on all sites. I chosen "Thin Borders" mode, for youtube you need change Thin border threshold to 0.43 to prevent the extension from working in wide mode. Others who write that it doesn’t work just don’t understand it well. Thanks to everyone dudes who developed this extension!

I'm not sure what the issue is, I tried it on both firefox and chrome and was unable to get it to work. I watched a tutorial from several months ago on how to use the extension, and following the instructions it still doesn't work for me. It very well could be a youtube update that disabled it. I am very frustrated because this extension solves my main issue, being that youtube has black bars on all four sides of my videos, essentially shrinking the picture on my ultrawide monitor.

Video does not align correctly when hybrid stretch is selected for youtube only. Video is in the right size but pushed half offscreen to the right. In fullscreen it works as intended but I don't use youtube in fullscreen

Esta extensión es prácticamente obligatoria si quieres sacarle el jugo a tu pantalla ultrawide, si no entiendes lo que hace te lo explico, si detecta un video con franjas negras arriba y abajo, entonces la extensión hace zoom y lo acomoda para que ocupe los 21:9 de tu pantalla, y lo hace de manera automática. Por ejemplo es muy útil al ver peliculas porque estas casi siempre traen esas franjas negras. En cuanto a la extensión confunde un poco el configurarla, pero mi recomendación es no muevas nada, tal como viene cumple bien. Si no te funciona reinicia el navegador o revisa las opciones de la extensión porque hay veces que te dice cual es el problema y como solucionarlo.

Extension settings no longer show up. This happened because the extension stated that hardware acceleration is broken, and go to: brave://flags/#use-angle and I changed it to OpenGL which messed up YT videos and they would flicker, so I tried the other setting they recommended: D3D9 and it stopped the flickering. That said, after I changed the setting to D3D9, and click on the extension, I am no longer able to see the settings -- just a tiny square box. However, if I change it back to OpenGL, I can see the settings, but also affects the video playback. I then changed it back to Default and broke the settings. TLDR; The settings only work if I set brave://flags/#use-angle to OpenGL.
