To display your Dell laptop screen on an Android TV using an HDMI cable, simply connect the two devices with the cable and select the correct input on your TV. This wired connection is direct and does not require internet or casting software.

Follow these step-by-step instructions:

1. Connect the Hardware

• Plug one end of the HDMI cable into the HDMI output port on your Dell laptop.
• Plug the other end into an available HDMI input port on your Android TV (take note of the label, e.g., HDMI 1 or HDMI 2).
• Note: If your Dell laptop is a newer thin model that lacks a full-sized HDMI port, you will need a USB-C to HDMI adapter or a USB-C to HDMI cable to connect to the TV.

2. Switch the TV Input

• Grab your Android TV remote and press the Source or Input button.
• Select the HDMI port number that matches where you plugged in the cable.

3. Configure the Laptop Display (Windows)

Once connected, your laptop should automatically detect the TV. If it doesn't, or if you want to change how the screen looks, configure it using these steps:

• Press the Windows Key + P on your laptop keyboard to open the Project menu.
• Choose your preferred display mode from the sidebar:
  • Duplicate: Shows the exact same screen on both your laptop and the TV.
  • Extend: Turns your TV into a second, separate monitor (allowing you to drag windows between screens).
  • Second screen only: Turns off your laptop screen and only displays content on the TV.

4. Fix Audio Output (If needed)

If the video is on the TV but the sound is still coming from your laptop:

• Click the Speaker icon on the bottom right of your Windows taskbar.
• Click the audio output selection menu (usually an arrow next to the volume slider).
• Select your Android TV or HDMI Audio Device as the output speaker.

Let me know if you run into any issues, such as:

• The TV screen displaying a "No Signal" error
• The image being blurry or cut off at the edges
• Having a newer laptop that only has USB-C ports

I can give you specific troubleshooting steps for any of these!
