This question already has an answer here:
I need a high-resolution monitor for multi-monitoring applications, but I don't have much room for a big TV. I had the idea of buying an iPad3 (2048x1536!) instead and sending the screen of a Windows XP running on a local computer over wlan. Is it possible without affecting the use experience - that is - 100% smooth? I've done the calculations for a 108mbits wlan (13500000bytes/s):
13500000 bytes/s / (3 bytes/pixel * (2056*1536) pixels/screen) = 1.42 screens/s
So I got a 1.5 fps without compression. With PNG compression plus sending only different pixels I guess it would be possible to reach a good 30fps; but I'm not sure if a computer is able to take 30 screen shots + compare 30 images + compress 30 images all in a sec. Is it?
