Works great on Win10 64-bit with iPad 2
Ive been using it as a 2nd monitor to run another browser for watching video lessons while coding on main monitor or controlling music apps. The only caveat was that initial configuration was not obvious. I had to go into Control Panel > Network & Internet > Windows Firewall > Advanced Settings > Inbound Rules > "iDisplay Server" for BOTH "public" and "private" to "allow" (green check mark) to get it to finally connect. Not sure if related, but I also installed/upgraded to latest iTunes on Windows so that the latest bonjour service was installed as I kept getting bonjour Windows event log app errors while troubleshooting connection issues. Also recommend complementing with Dexpot virtual desktops and UltraMon both for Windows to make a great multi monitor experience.
