DisplayBridge App

Use your old iMac as a monitor for your MacBook — full 5K at 60 Hz over one Thunderbolt cable. No conversion kit, no Target Display Mode.

I'm a computer science student in Switzerland and built DisplayBridge: one app that turns any Mac into a display for another Mac. Extend your desktop, mirror your screen, or close the MacBook lid and keep working on the iMac — with sound over the same cable.

On this channel: step-by-step setup guides, comparisons with the conversion kit, and my desk with three 5K iMacs.
