I had been using my laptop to run Zwift and it worked great. I got an Ant+ adapter and it picked up all my sensors. I was also able to use the Zwift Mobile Link app, too. However, since I was sharing the laptop with my son it became difficult to ride when he was using the machine, and he was starting to use a lot more frequently. That meant that I needed another solution.
I was picking up my Synapse at Brookfield Bicycle Center after getting it overhauled, I think I had a 3K miles on the cassette and chain, and it was shifting like crap, and as I was talking to Shawn about Zwift he showed me this dongle called an Apple Lightning Digital AV Adapter. It has two ports, one for power and another for HDMI, which meant I could connect my iPhone directly to my TV and run Zwift that way.
