My guess would be they're just using the shared documents area . There's a number of libraries on the desktop that let you access an API to write to the shared documents area. I'd guess they'd just be piping a mp4 feed to this and the iOS would just be reading from there.

Is there any chance this approach could eventually be used on a Linux distro or Windows?

I do a lot of reading / annotating on my iPad. My other use case mostly involves emacs. I'd love to have a Linux matchstick dongle that I could simply plug in to my iPad to run emacs (and associated goodies like R, Python, etc).

This is really interesting technically, a couple tidbits I dug up looking in the mac app bundle: 1. There are a couple of OpenGL shaders in the bundle for converting the screen image to HDTV color space/format (420v.fgsh) and some kind of passthrough. 2. They appear to be using x264 to encode the screen with defaults of 1280x720, 1000kbit, superfast preset. (Defaults.plist) So on the mac side, they're definitely capt…

My guess is it's using Apple's version of RNDIS ... iPad becomes a network peer of the Mac and streams video over that network.

But I don't believe that API is public, so I can't know for sure...

This isn't the first app that lets you do this, is it? It might be better (or worse) in performance, but the functionality has already been made available in the past, right? Just want to check. Also, this is neat but I wish it were integrated into OS X + iOS as part of AirPlay. I love AirPlay and want to see it expand to cover all possible permutations (iOS -> OS X screen/audio/both sharing, as well as OS X -> iOS s…

I've used an app called Air Display to do the same thing for quite a while, but instead of USB it connects over WiFi - which is convenient, but the refresh rate is slow. I used it mainly to have my chat client on a 3rd screen.

I know this is nit-picky, but Duet is not "the first app that allows you to use your iDevice as an extra display". It's not even the second. There's an opportunity here for better copy to differentiate themselves. Also, I've always thought this would reduce the life of your ipad. Has anyone noticed this?

you chopped off this part "...iDevice as an extra display for your Mac using the Lightning or 30-pin cable"

Am I a little too slow here or they just launched the Mac app without the iOS counterpart? Can't find it on App Store.

You're too fast, the release date for the iOS app is 16th december.

Duet is still waiting in line for approval in the app store. Launch is later this week.

Woah, do you know if this works with the new retina display iMacs?

I'm here to confirm to you that it doesn't. Sorry buddy, wish it did myself. 5K is out of reach for most MBP's (if not all).

That's a bummer, it would be worth buying a new iMac for the screen alone.

So uh, why is the marketing being done today when the release is tomorrow? I'll probably have forgotten about it by then. I wouldn't mind it though, the other ones (using wifi streaming) never really worked for me. And I wonder why this isn't a default feature in iOS / OSX.

So uh, why is the marketing being done today when the release is tomorrow? They want your email, Twitter following, and other things that are more useful over time than your casual perusal after launch.

Actually a bit simpler, Business Insider released the article to fill their timeline not Duet's launch date. The app is still awaiting review and with the app store being so busy this season it's hard to give a hard date. Expected to be released later this week.

It is called AirDisplay and available since years: https://avatron.com/applications/air-display/ I think there was/is also another App available doing it.

I've used Air Display, but that's over Wifi.

These guys claim to be using the lightning cable. Which means maybe, just maybe, I can plug two of them in at once.

> the first app that allows you to use your iDevice as an extra display for your Mac I stumbled upon iDisplay.com the other day. Can't recommend anything though, I'm not an apple user, I was looking for ways to replicate my android phone display in my desktop Linux.

Yeah, that statement is purely false. AirDisplay[1] does pretty much the same thing and has been out for years. [1]: https://avatron.com/applications/air-display/

the commenter misquoted, the rest of the sentence is "... iDevice as an extra display for your Mac using the Lightning or 30-pin cable."
