Why stream your PC screen to your phone?
Using your phone as an auxiliary or emergency PC screen solves real frustrations:
- Cracked or dark laptop monitor: A dropped laptop with a broken screen still has functioning internals. Put the desktop on your phone or tablet and rescue your files or finish your assignment.
- Second screen for chat or guides: Keep Discord, Spotify, or a game walkthrough open on your phone screen next to your monitor while you game in full-screen on your PC.
- Headless media PC in a closet: If you run a Plex server or file server without a dedicated monitor, check on background tasks from your couch instead of carrying a monitor across the house.
- Watch movies in bed: Watch video files playing on your PC directly on your phone screen with synchronized PC audio streamed to your earbuds.

How touch clicks map to Windows elements
When you look at your PC desktop on your phone screen, you don't need a separate mouse. Tapping on a folder icon or browser button maps directly to that coordinate on Windows. Tapping with one finger performs a left click; holding or tapping with two fingers performs a right click.
