To kill the screen latency, you could use Miracast, which seems to be much faster than the chromecast (see https://www.youtube.com/watch?v=J-5JJhKMph8 https://www.youtube.com/watch?v=J-5JJhKMph8) or connect a cable (best solution: no heat because of the video encoding, can recharge the phone with MHL, no lag). Also one issue would be the DPI. Working with the big android elements on a, say, 24 inch screen would be a pain. But maybe you could automate a DPI change to rescale the whole interface.
