About Wi-Fi you can mirror the PC screen contents to the projector. For this projector in a mini-web server (THTTPD) is installed, from which you can download the program required for this purpose. For this you have to type in only the IP address that appears as soon as you activate the access point function in the projector. With me but only got the 403 error (file access forbidden) because the server Windows EXE would not budge from the Linux CGI directory. The necessary file EZ_WiFi_LAN_Mirror-only.exe you can (for a few days - not then) Download from de ASUS website. As the name suggests, only the mirror function is possible. If you want to turn on WLAN the screen to undisturbed to watch a movie on the wall, you have bad luck. Therefore is only suitable for presentations. Through the extreme wide-angle lens but you can not provide the whole picture sharp. The falls when watching movies not to continue. In presentations with much writing, it disturbs but pretty. Otherwise there is not much to complain on the device. It has countless connections and settings and is to satisfy even the most unusual wishes able. I will buy the device me again later, when the firmware (hopefully) be error free. Or wait for the successor.
