UltraWideo bởi nonwip

Stop watching videos with black bars eating half your screen.

UltraWideo removes black bars and resizes any video to fill your display — on literally any site that plays video. One click, instant result.

Made for EVERY screen — not just ultrawide
Ultrawide monitor (21:9, 32:9), a regular 16:9 laptop or TV, or watching old 4:3 uploads? UltraWideo reshapes the video to fit your screen perfectly. No more black bars on the sides. No more black bars on the top and bottom. Just full, edge-to-edge video.

Why people switch to UltraWideo
Other extensions break on certain sites, stop detecting the video, or wreck the page layout. UltraWideo doesn't. It finds videos automatically — even tiny embeds and players hidden inside other players — and only activates when there's actually a video to fix. No "video not detected." No broken pages.
