This article explains how to wirelessly project (screencast) your computer or Android device to a display that does not have built-in smart capabilities. It includes step-by-step instructions for using both a direct device connection and a wireless display adapter.

🔹 1. Prerequisites

Before you begin, make sure you have the following:

• A display (TV, monitor, or interactive panel) with at least one available HDMI port
• A computer or Android device capable of screencasting
• Either:
  • A wireless display adapter (e.g., Chromecast, Microsoft Wireless Display Adapter, EZCast, Airtame)
    • Example here: https://a.co/d/ep41GNz 
  • Or a compatible video cable (HDMI, DisplayPort, USB-C)

🔹 2. Screencasting with a Wireless Display Adapter

Wireless display adapters allow you to transmit your screen content without a physical connection between your device and the display.

Setup Steps

1. Connect the adapter:
   • Plug the HDMI connector of the wireless adapter into an open port on your display.
   • Connect the USB power cable to a USB port on the display (or a wall adapter, if required).
2. Set the display input:
   • Use the display’s input/source button to select the HDMI port where the adapter is connected.
3. Confirm adapter setup:
   • A setup or standby screen should appear—this means the adapter is ready for connections.

Casting from a Windows 10/11 Computer

1. Ensure your PC and the wireless adapter are on the same Wi-Fi network.
2. Press Windows + K or go to:
   • Settings → System → Display → Connect to a wireless display
3. Wait for your adapter’s name to appear (for example, “Wireless Display Adapter” or “Chromecast”).
4. Select it to connect.
5. Once connected, your desktop will appear on the display.

💡 Tip: Use Windows + P to switch between Duplicate, Extend, or Second screen only modes.

Casting from an Android Device

1. Make sure your phone/tablet and adapter share the same Wi-Fi network.
2. Swipe down from the top of your screen to open Quick Settings.
3. Tap Cast, Smart View, or Wireless Display (the name varies by manufacturer).
4. Select your adapter from the list.
5. Confirm connection if prompted.

🔹 3. Screencasting with a Physically Connected Device

If you prefer a reliable wired connection or your environment doesn’t support wireless networking, you can connect your device directly using a video cable.

Connecting a Computer

1. Plug one end of the HDMI or DisplayPort cable into your computer.
2. Connect the other end to the display’s corresponding input port.
3. Use the display’s input/source control to select the connected port.
4. Your desktop should appear automatically.
   • If not, press Windows + P and select “Duplicate” or “Extend” display mode.

Connecting an Android Device

1. Use a USB-C to HDMI adapter (ensure it supports video output).
2. Connect the adapter to your Android device and attach the HDMI cable between the adapter and the display.
3. Switch the display input to the correct HDMI port.
4. The Android screen should mirror automatically.

🔧 Note: Not all Android phones support video output via USB-C. Check your manufacturer’s documentation under “Display or video output support.”

🔹 4. Troubleshooting

🔹 5. Summary

Even without smart features, you can easily mirror or extend your screen to a display using:

• A wireless display adapter for flexible, cable-free projection.
• A physical HDMI or USB-C connection for direct, dependable performance.

Both methods allow you to display content from your device on a larger screen for presentations, meetings, or entertainment.
