Remove the black bars from YouTube on your ultrawide monitor
Click the button with the four corners to fill the screen.
- Nothing gets stretched
- The video zooms in from the center, so a bit of the top and bottom is cut off. On 21:9 that's about a quarter of the height, and on 32:9 about half.
- It remembers the setting
- Once it's on, it stays on for every video, after you refresh, and in theater mode and fullscreen. Click the button again to turn it off.
- No tracking
- No ads and no account. It only runs on youtube.com, and the only thing it saves is whether it's on or off.
- What it can't do
- If the black bars are part of the video itself, they stay. It only works on youtube.com in a desktop browser, not on phones, TVs or videos embedded in other sites.
See it work
A short video of Fullorama on YouTube. You'll see the black bars, the button, and the video filling the screen after one click.
Reviews
“It works. Very lightweight. Adds a button to the youtube interface very convenient.”
Dude“A really cool, useful extension. On a Redmi 34" it works and looks great, but you have to set YouTube quality to 4K, and it doesn't work on every video.”
“очень классное полезное расширение, на redmi 34"/2026 работает и выглядит отлично, но приходится ставить Качество Ютуб 4к и работает не на всех роликах”

Install Fullorama for Chrome or Firefox and play any YouTube video. Look at the bottom-right of the player: there's a new button with four little corner brackets, next to the settings gear. Click it and the video zooms in to fill the player. A small square appears in the middle of the icon to show it's on. Click it again to go back to normal.
It's with YouTube's own buttons at the bottom-right of the video, between the settings gear and the theater-mode button. Move your mouse over the video if the controls are hidden. If the button isn't there, refresh the YouTube tab once. Tabs that were already open when you installed Fullorama don't get it until you do.
No. Fullorama zooms in evenly from the center, so people and objects keep their normal shape. The trade-off is that a little of the top and bottom gets trimmed. There's no stretch option.
Some videos have the bars recorded into the picture itself, often old movies or re-uploads. Fullorama can't tell those apart from the real image, so they can stay even with the button on. It also can't show picture that was never in the video.
Yes. When you switch to theater mode or fullscreen, the zoom adjusts automatically to fill the new size.
No. Turn it on once and it stays on as you watch more videos, refresh, or browse around YouTube. Turn it off the same way whenever you like. The setting applies to all of YouTube in that browser.
Yes. Fullorama works out the zoom from your player's shape, so it fits 21:9, 32:9 and anything in between. On very wide screens, more of the top and bottom gets trimmed, because the video has to zoom in further to fill the width.
Not if the video and your screen are different shapes: filling the space without stretching always trims a bit off. If you'd rather see everything, turn the button off and keep the bars.
No, only YouTube in a desktop browser (Chrome or Firefox). It doesn't work on Netflix, Prime Video, other websites, or the YouTube app on phones and TVs.
It just zooms in on the video that's already playing, so it doesn't change the video's quality or load anything extra. Zooming in won't make it sharper, either. We haven't measured its performance impact, so we won't promise a number.
Clicking Fullorama's icon in your browser toolbar shows whether the zoom is on or off, and has a link to send us feedback. To turn it on or off, use the button in the video player.
No. It saves one thing in your browser: whether the zoom is on or off. It doesn't track what you watch, has no ads, and needs no account.
Feedback is optional and goes through a separate form run by Tally. It opens if you choose "Share feedback" in the toolbar popup, or after you uninstall. The form link includes the extension's version and where you opened it from. On Firefox, those two details are only sent if you've allowed the optional data permission.
