Working from your Tesla but stuck on one laptop screen? SideDisplay turns your Tesla's touchscreen into a wireless extended monitor — not mirroring, a true second display. Drag windows across, run Slack on one screen and your IDE on the other. It runs over WebRTC through the built-in browser — zero hardware needed. Just USB tether your phone for internet and you're set. Mac and Windows. And it's not just Tesla — any device with a browser and Wi-Fi works too. Up to 3 displays. Try it free.
