Duplicate Browser Screen

Duplicate a window, screen, or browser tab using Chrome's picker (window preselected). Includes zoom, pan, and utility options.

Duplicate Browser Screen allows users to duplicate any browser window and move the duplicate to a second screen. This functionality is especially useful in presentations, karaoke sessions, or multitasking scenarios where the same content needs to be displayed on multiple monitors. With Duplicate Chrome Screen, users can open their browser, activate the extension, and select the window they want to duplicate. The duplicated window can then be moved to a different monitor, making it perfect for events like karaoke, where the lyrics need to be displayed on a separate screen while the main window remains under control. The same applies to presentations or live streaming, where presenters and streamers can keep an eye on the main content while showing it to their audience on a different screen. The extension offers seamless performance with minimal lag between the original and duplicated windows. It’s intuitive, quick to use, and requires no complicated setups, making it accessible to everyone, from beginners to professionals. Duplicate Chrome Screen is an essential tool for anyone who needs to mirror content across screens effortlessly and efficiently, whether for entertainment, work, or teaching purposes. 🎯 Why you’ll love it 🔁 Duplicate to a second monitor in a click ⚡ Low-latency viewing for smooth, near-real-time playback 🧭 Simple workflow: open the browser, click Duplicate Screen, pick what to share (Window/Screen/Tab), then drag the viewer to the other display 🧰 Helpful controls 🔍 Zoom in/out (with keyboard and wheel) ✋ Pan the view when zoomed ↹ Fit / Fill (double-click to toggle) 🎯 Center stage (reset position) ⛶ Fullscreen 🖱️ Right-click menu with quick actions 🎬 Great for 📽️ Presentations & events — keep controls on your main screen, show content on the second 🎤 Karaoke — lyrics on the external display, controls stay private 🎓 Classrooms & training — share exactly what students need to see 📺 Live streams & demos — manage the primary window while the audience sees the output 🔒 Privacy-friendly Runs entirely in your browser—no accounts, no uploads, no complicated setup.
