At the moment NO touchscreen will work reasonably, it seems. Even the ones that are recognized won’t respond correctly, because the dLive system seems to “fake” a screen of double horizontal resolution when an external screen is attached. So 1024×768 internal plus 1024×768 external results in 2048×768 as seen by the system. Now th external screens touch mechanism is mapped to that full resolution, so when pressing the right side of the external screen, you will get the right side of the external screen, but touching slightly right of the middle of thae external touchscreen will land you on the far left side. Every touch left of the middle will lead you to the internal screen! So it’s pretty much unusable. I tried that with two different touchscreens, one I lent and one of my Asus VT168H. Both are recognized as in reacting to touch, but just not in the touched places…
