    I doubt this is possible but will ask anyway ... Is it possible to use the iPad Pro as a Cintiq ? Extra monitor that you can use the pen on?

    Nothing like that that I know of as of yet. But I've seen the capability to use the iPad as a 2nd monitor so I'm sure it would be completely possible.

    If you're doing artwork, there's Astropad that can sort of mimic a Cintiq. I've used it briefly to paint in Photoshop and a little bit of Flash.

    There's also DuetDisplay, but I personally haven't tried that app yet.

    That's exactly why I bought the iPad Pro. Already own 2 Cintiqs and want to go cordless. Price is comparable for what you get. Can also use it for client presentations.

    Will still use Cintiq for more heavy duty work - but this will allow me to work on sketches and storyboards when not in front of my workstations.

    Astropad works, but it's laggy. You're essentially running Steam Home Streaming, which means the host has to capture and encode a video stream then send it over USB to the iPad which renders it like any video stream. Input goes back the other way and is converted into something that makes sense to the host machine.

    Best case scenario (wired, host has a solid GPU with hardware video streaming like a modern nVidia card with ShadowPlay) you get 30ms of added lag and some mpeg compression noise (probably more lag if you want to use more than 1080p). In my experience it's much laggier, but i don't have an OS X desktop to test as the host.

    The best solution involves a video capture device in the chain. That's basically how iMac target mode works: The iMac has some internal video capture hardware and so it can take HDMI/DP input and render it on screen. I'm sure iPP doesn't have this, but it would be possible to have a separate device that performs the video capture and then feeds the data to the iPP over USB. 2.0 might be workable, but we know it theoretically supports 3.0 so there's plenty of bandwidth. Wireless a/c might work too, but wifi has a less reliable packet stream which will require adding a buffer (and lag). You'd still have an app on the iPP that renders the video stream and sends input back to the host.

    That probably sounds like the same system (and it is on the client end), but the difference is that we're no longer doing video capture/encoding/streaming on the host, which is the biggest source of lag (+ wasted CPU/GPU time). The host machine just outputs to display port like it's going to a monitor, and the capture device makes that data into a video stream for the client. Cintiq Companion 2 use this exact system, but like the iMac it has internal capture hardware.

    In fact if no one is working on this system already then, you know, maybe I should stop telling people about it and get to work. ;)

    I've used Astropad with my 5K iMac. Works beautifully. As long as you have a fast internet connection and are close to the router, there is almost no lag. If not, you can still connect via usb and it works beautifully. Already plays heavily in my workflow.
