iPad as a second screen
So, does anyone have any experience or tips for using an iPad as a screen extension or mirror for an android handheld? Would be a wired connection for latency, I hope, just wondering if this is reasonably possible?
I can 'dock' my SBC at the moment to my PC monitor but then it doesn't have sound unless I connect earphones, and I can't easily toggle the resolution (pocket dmg, still troubleshooting the problem, think I need to use a direct cable and not a dock, or a different dock).
I have a 4:3 device that can comfortably run some 16:9 / wider consoles, but I wouldn't do so unless docked, and I'm wondering if I could utilise the gorgeous retina screen on an iPad Air 4 I have lying around.
I've done a good bit of searching, and I haven't seen many use cases for android into iPad, but lots of windows into either (Mac/android tablets) or even some Linux and Ubuntu, surprisingly.
That tells me it's either not easily done, impractical, or I'm making some glaring oversights.
Anyone have any experience or input to share? Cheers.
