Package Contents: Please check the following items are included in your Wi-Fi Display package: „ Main Unit X1 „ Antennas X2 „ 5V/2A Power Adapter X1 „ Installation CD X1 „ User’s Manual (In the CD) X1 Wi-Fi Display User’s Manual - 4 - 2. Before you start Wi-Fi Display is the one device that can show all contents of your Windows® or Mac® computers on your TV wirelessly. You can easily control computers with your mouse and/or keyboard. You can share any content from your computers with your friends and family in your living room. Also, if your mobile phone or pad is Android OS with a built-in DLNA function, you can push the picture, music and audio from Android mobile devices to HDTV for sharing a big screen. Also,if your home Router have no Wi-Fi function, connecting this product to your home Router,you will get a Wi-Fi Router, then all mobile network devices can also access into the Internet,such as personal notebook, mobile phone,etc. Setup Possibilities: a) Ethernet Connection: Best performance for Windows or Mac computer Whenever possible, always use Ethernet cables to connect Wi-Fi Display device to your home network. This setup provides best performance for both remote operation and internet connection. b) Partly wireless Connection: Reasonable Performance for Windows or Mac computer If wireless connection is preferred, you can connect your home AP and Wi-Fi Display via cables, and access either from your home AP or Wi-Fi Display. Wi-Fi Display User’s Manual - 5 - c) Purely wireless Connection: Basic performance for Windows or Mac computer You can also try setting up Wi-Fi Display as a wireless client to your home AP via AP-Client mode. However, this setup is more complicated and vulnerable to any interference in Wi-Fi signal. d) DLNA function for Android mobile devices if your mobile phone or pad is Android OS with a built-in DLNA function, you can push the picture, music and audio from Android mobile devices to HDTV for sharing a big screen. For some mobile devices, maybe some media format can not be supported on this product.

Quick Start 1. Connect the HDMI output on the Wi-Fi Display to your TV, and turn on your TV. 2. Connect the power adapter to your Wi-Fi Display, and plug in to your power outlet. 3. Press the Power button on Wi-Fi Display to turn on the device. 4. Wi-Fi Display will be powered ON. Waiting for about 35 seconds,the Main Menu as below will be shown on your TV screen while system is ready. 5. Insert Wi-Fi Display CD and follow on-screen instructions to install software from the CD-ROM. 6. Find the following icon in "Applications\MirrorOp" folder (on Mac) or "Programs\MirrorOp Sender" folder (on Windows) to launch MirrorOp Sender. 7. Search Wi-Fi Access Point. Select your Wi-Fi Display device (default SSID is MirrorOp) from the list and click the Connect button. Wi-Fi Display User’s Manual ‐ 8 ‐ 8. Connect to selected access point. 9. Connect to MirrorOp server. If only one server is found, it will automatically connect to the server. 10. The application will ask to adjust your PC resolution for best projection result, and then project your screen to TV. You should see your PC Desktop on TV screen now. 11. To finish projection, click the X button on the menu of MirrorOp Sender to leave projection. Your screen resolution would be restored to original one if you approve adjusting resolution with above step. Wi-Fi Display User’s Manual ‐ 9 ‐ 4.
