Short, practical guides to everything UltraWideo can do – what each feature is, why it helps, and how to get the most out of it.
The essentials – install the extension and every one of these is yours, no account needed.
Normal, Upscale, Stretch, Custom – pick how the video fills your screen.
Dial in the exact zoom and shift the frame to fit any screen.
Keyboard shortcuts and mouse/trackpad gestures for hands-on control.
Theme, accent colors, language, auto-hide, and notification prompts.
Per-site configs, ambient light, voice control, and more – the tools that make it effortless.
A different config per site or URL, applied automatically on arrival.
Remove black bars encoded into the video itself, automatically.
A real-time glow that extends the video's colors past its edges.
Adaptive sharpening that scales with the source – no halos, no noise.
Hide modes you don't use so the cycle only flips through your favorites.
Just say what you want – "make it bigger", "crop the black bars".
