Modes Reference

Mode Description
Off No transform applied. Video plays at its native size — black bars may be visible on ultrawide displays.
Fill Horizontally stretches the video to fill your monitor's full width. Best for content where slight distortion is acceptable.
21:9 Crop Crops the video to a 21:9 cinematic widescreen ratio. Removes black bars on standard 16:9 content viewed on 21:9 monitors.
32:9 Crop Crops the video to a 32:9 super-ultrawide ratio. For 49-inch super-ultrawide displays.
Auto Reads the video's actual native aspect ratio and scales it to fill your ultrawide monitor. Most accurate mode for mixed content.
Zoom Custom zoom level from 30% to 300%. Zooms both X and Y axes uniformly. Use the slider, ± buttons, or Alt+↑/.

Frequently Asked Questions

The extension isn't doing anything on this site — why?
The extension requires an HTML5 <video> element on the page. Some streaming sites (older Flash-based players, DRM-protected iframes, or desktop app wrappers like Spotify) don't expose a standard video element. The green dot in the popup will light up when a compatible video is found.
The video resets to normal after I skip or change quality — how do I prevent this?
The extension uses a MutationObserver to re-apply transforms when the DOM changes. On some sites the player swaps the <video> element entirely during quality changes. This is a known limitation. Toggling the mode off and on again will re-apply the transform.
Will this work on Netflix or Disney+?
Yes, both sites use standard HTML5 video elements. Note that DRM content may have additional restrictions. If the green dot shows a video is detected, the modes will apply.
What's the difference between Fill and Auto Force Aspect?
Fill stretches the video horizontally to match your exact monitor width — it only scales the X axis. Auto Force Aspect reads the video's native ratio first, then calculates the minimum scale needed to fill your monitor without distortion — it may scale X or Y depending on the content.
Can I configure which modes cycle with Alt+C?
Yes. At the bottom of the popup, you'll find the "Cycle modes" section. Click any chip to toggle a mode in or out of the cycle. At least two modes must remain active.
Does this extension collect any of my data?
No. See the Privacy Policy for full details. Your preferences are stored locally via Chrome's built-in sync storage and never sent to any server.
The keyboard shortcuts conflict with another extension — can I change them?
Yes. Open chrome://extensions/shortcuts in your browser and reassign the UltraWide Pro commands to any combination you prefer.
I found a bug or have a feature request — where do I report it?
Email russel.sese@batchee.com or reach out via LinkedIn. Include the site URL, your monitor resolution, and which mode was active.
