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.

There are plenty of apps which have done this before - but only over Wifi. This is wired, so you don't get the same issues with lag.

...and then yosemite came out, the the fps dropped from 25 to 2, and everyone stopped using it.

The same goes for DisplayPad.

The key here is that this is not a wifi streamcast.

I've occasionally used AirDisplay when doing minor HTML/CSS stuff (browser on iPad, emacs with impatient-mode on Mac) and it's useful, nice, but when doing heavier lifting lag kills it. I'll definitely be getting it tomorrow, and look forward seeing if I get to use it more or "as often as I did."

This looks cool - I'd definitely use it for emails. Has it not been done already though? I have a question about the image - whats the stand used for the iPad?

Isn't the point of leather that it wears?

I wonder how they achieve "Zero lag". I've been using similar software ( AirDisplay [1] ) and the lagging is awful. You have to be certified hardware manufacturer if you want to use the USB connection to transmit any data between the iPad and your Mac [2]. So my bet is they either use WiFi ( which can roughly get 60fps on retina resolution ) or Bluetooth 4. In both cases I think the refresh rate would not satisfy in…

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?
