Your Tesla screen is now a wireless second display
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.
Hey Product Hunt! 👋 I'm S.Lee, the solo developer behind SideDisplay.
I built this because I kept wishing for a second monitor while working from my Tesla. I wanted a real extended display where I could drag windows across and actually multitask.
SideDisplay uses WebRTC to turn your Tesla's touchscreen into a true wireless extended monitor for your Mac or Windows PC. No dongles, no cables, no hardware mods. It runs right through the built-in browser.
And here's the thing — it's not limited to Tesla. Any device with a browser and Wi-Fi works: tablets, smart TVs, even other cars. Tesla is just the flagship use case.
A few highlights: 🖥️ True extended display, not mirroring — drag windows across screens 📡 Wireless via WebRTC, ~100ms latency 🔗 Connect up to 3 screens simultaneously 💻 Mac (Apple Silicon, macOS 15+) and Windows 11 🆓 Free trial: 60 min/week, no credit card needed
I daily-drive this myself — my Tesla's touchscreen is always my second monitor. It's the setup I always wanted.
Would love to hear your thoughts — especially if you've tried working from a car or wished you had a portable second screen on the go. What use cases would you try first?
