Have a look at DisplayLink http://www.displaylink.com/ it can create a wireless display link between tor HTPC and tablet, The screen will be recognized on your HTPC as another screen and MPDisplay can run that way.
However with the new architecture of MPDisplays skin engine it is now possible for other developers to create native Android/iOS applications that run the existing MPDisplay skins, however I myself do not have the time for this but hopefully someone is keen
I have found this one, can it works with your plugin ? iDisplay
I have a look at this monitors. But wireless are better than this. So i must go to the HTPC and go prone to use the second monitor.
And here is another one. I need one app how make a my tablet as monitor and windows will check that and connect as second screen, then i can use your plugin ?
Ok when i read the last site right, than it dont work with mp 1.4 or 1.5 . So i have to wait. I think i have a solution that it can work with my tablet. I have installed iDisplay for Windows and an app for my tablet. It works fine so far. Do i need to set duplicate monitor one ? Or i must only choose the second display in mpdisplay config ?
