The primary drawback is latency. Because the screen is being streamed, there will always be some delay. This makes software solutions less ideal for fast-paced activities like gaming.

Remote Desktop Software: Taking Control

Remote Desktop Software (like RDP, TeamViewer, or Chrome Remote Desktop) lets you control one computer from another.

Think of it like sitting in front of your main computer, even when you’re physically using your laptop. You see and interact with everything on the main computer’s desktop.

How It Works

Remote Desktop software establishes a connection between two devices, allowing you to remotely access and control one computer (the "host") from another (the "client").

This is done through graphical user interface. The client device will display the desktop environment of the host and permits actions such as keyboard and mouse control.

Latency Considerations

Using Remote Desktop software introduces a noticeable lag between your actions and what you see on the screen.

This latency can be significant, especially over slower network connections. You’ll likely notice this delay when moving windows or typing. It’s generally not suitable for video editing or playing games.

4. Connect from the Client Computer: On your laptop, open the Chrome Remote Desktop extension. You should see the host computer listed. Click on it, enter the PIN you created earlier, and connect.

With this configured, you have a fully functional Remote Desktop where the monitor of your main computer is effectively your laptop’s extended display.

Virtual Network Computing (VNC): Another Approach to Screen Sharing

Virtual Network Computing (VNC) is another screen-sharing technology. VNC operates on a client-server model.

The "server" component runs on the computer whose screen you want to view and control. The "client" runs on the device you’re using to access the server.

How It Works

The VNC server captures the screen output and sends it to the VNC client. The client then displays this output, allowing you to interact with the remote computer using your mouse and keyboard.

Latency Considerations

Like Remote Desktop software, VNC introduces some degree of latency. The amount of latency will depend on your network speed, the processing power of both computers, and the VNC software you are using.

Setting Up VNC

Here’s a general overview of how to set up VNC:

1. Choose a VNC Solution: Several VNC solutions exist (e.g., RealVNC, TightVNC, UltraVNC). Choose one that suits your needs.
2. Install the VNC Server: Install the VNC server on the computer you want to access remotely.
3. Configure the VNC Server: Configure the VNC server with a password and any other desired settings.
4. Install the VNC Client: Install the VNC client on your laptop.
5. Connect to the Server: Open the VNC client and enter the IP address of the computer running the VNC server. Enter the password when prompted.

Once connected, you’ll see the remote computer’s screen on your laptop.
