Frequently asked questions
Do I need any extra hardware?
No. You only need an iPad or iPhone and a Mac on the same WiFi network.
Does this mirror my screen or extend it?
It extends your desktop, giving you additional workspace rather than just duplicating what is already on your main display.
Does it work over WiFi or does it need a cable?
It works wirelessly over WiFi. No cable is required.
Is there a lag using a wireless second screen?
Performance depends on your WiFi network quality — a strong, stable connection gives the smoothest experience.
More screen space without buying a monitor
A second monitor is useful but takes up desk space and costs money you may not want to spend for occasional use. If you already own an iPad or iPhone, Second Monitor turns it into extra workspace over WiFi — no new hardware, no cables.
