Duet Display second screen app turns iPad into second monitor for iOS and OS X now available

[froggyboy604]

Duet Display is promised to trump other second screen options out there, with its makers saying it has no lag and is high-quality. You can see those claims substantiated for yourself in the demonstration video below. In addition to extending your Mac's display, it supports the iPad's touchscreen functions, as well.

Duet Display for Mac is free, but the iOS version will run you $9.99 USD on iTunes and use up about 50MB of space.

This does look like a cool app for adding an extra display to a Mac. But, there are $89 USB 3.0 16 inch monitors which cost less than a $500 iPad, and has a bigger screen as well.

$9.99 is kind of expensive for an App. I bet, it would be cheaper to buy a regular monitor to plug into a Mac's HDMI port or Display Pro than to use an iPad Air 2 which cost $500 for the cheapest model with 16GB of storage. Plus, buying an extra charging cable for the iPad will cost about $20.

its nice if you have it, but not something you want to buy for this purpose.

I agree this app is nice to have if you have an iPad, extra cable, and ipad stand and have $10 to buy this app.

But, I bet the video on ipad may lag a little if you use the iPad screen and USB iPad cable connected to a Mac for gaming compared to a LCD monitor with HDMI monitor which is designed for PC, Mac, and newer game consoles where the HDMI connection is directly connected to the video chip or video card.
