Methods to Use a Laptop as a Second Monitor
There are several ways to transform your spare laptop into a functional second display. Each method has its own set of advantages and disadvantages, and the best choice for you will depend on your technical skills, budget, and specific requirements.
Using a Wired Connection (HDMI Capture Card)
One of the most reliable and low-latency methods involves utilizing an HDMI capture card. This device essentially allows your second laptop to “capture” the video signal from your primary computer via an HDMI connection. Think of it as a bridge that allows one computer to read the signal from the other.
The primary advantages of this approach are lower latency and potentially higher image quality. Because the connection is wired, the signal is transmitted directly, minimizing delays and ensuring a crisp, clear image. A stable connection is another benefit.
However, this method requires purchasing an HDMI capture card, which can add to the overall cost. Additionally, you may need to install drivers for the capture card on your second laptop, which can be a bit technical for some users. It can be more expensive than purely software solutions.
Here’s a general guide to get this setup working:
First, connect one end of the HDMI cable to the HDMI output port on your primary computer (the one you want to extend the screen from). Then, connect the other end of the HDMI cable to the HDMI input port on your capture card. Next, connect the capture card to your second laptop (the one you are using as the monitor) via a USB cable.
Once the physical connections are secure, turn on both laptops. You may need to install the appropriate drivers for your HDMI capture card on your second laptop. These drivers are typically available on the manufacturer’s website or included with the capture card. After the drivers are installed, open the software that comes with your capture card. This software will allow you to view the video signal being captured from your primary computer. Configure the display settings within the capture card software to match your desired resolution and refresh rate.
Using Software Solutions (Wireless or Wired)
Another approach involves using software solutions that allow you to connect your two laptops either wirelessly or through a wired connection, such as a USB cable. Several software options are available, each with its own unique features and pricing models.
Spacedesk
One popular choice is Spacedesk. Spacedesk is a free software application that utilizes your network to connect the two devices. It essentially turns your second laptop into a remote display for your primary computer.
The advantages of Spacedesk are its cost (it’s free!), ease of use, and cross-platform compatibility. It works with Windows, Android, and other operating systems.
However, performance can be heavily dependent on the strength and stability of your network connection. Wireless connections can be prone to latency, which can result in noticeable delays between actions on your primary computer and their appearance on the second laptop’s screen. Also, it requires software installation on both laptops.
To use Spacedesk, first download and install the Spacedesk Driver software on your primary computer. Then, download and install the Spacedesk Viewer application on your secondary laptop. Ensure both devices are connected to the same network (preferably a stable Wi-Fi or Ethernet connection). Open the Spacedesk Viewer application on your second laptop. It should automatically detect your primary computer running the Spacedesk Driver. Select your primary computer from the list, and the connection should be established, extending your desktop to the second laptop.
Duet Display
Another option, that is not free, is Duet Display. Duet Display is a paid software application that is known for its performance and features, including touch support (if your second laptop has a touchscreen). It provides a more refined and responsive experience compared to some free alternatives.
The advantages of Duet Display include better performance and touch support. The downsides are that it is a paid product and requires installation on both devices.
To use Duet Display, simply download and install the application on both your primary computer and your secondary laptop. Follow the on-screen prompts to connect the devices. Duet Display typically works best with a wired connection via USB cable for optimal performance.
When considering software solutions, keep in mind that a strong, stable network connection is crucial, especially for wireless setups. Also, check the software’s compatibility with your operating systems before installing. Potential latency is a common issue, particularly with wireless connections, so experiment with different settings and network configurations to minimize it.
Windows Built In Functionality (Project to a Wireless Display)
Windows operating system has built in functionality to project to a wireless display.
Using windows own screen projection is advantageous because it does not require any additional software. The connection is easy to setup.
However, it can be very laggy and not stable. This method can also drain the power from both laptops.
First, click the Start button on the laptop you want to use as the monitor. Then, click Settings > System > Projecting to this PC. Setup the projecting preferences to your liking. On the primary laptop, the one you are extending the screen from, click Start > Connect and select the secondary device.
Optimizing Performance
Regardless of the method you choose, there are several steps you can take to optimize performance and minimize latency.
Network optimization is key, especially for software-based solutions. Using a wired Ethernet connection is generally preferable for lower latency and a more stable connection. If you’re relying on Wi-Fi, make sure you have a strong signal and consider using a five GHz network, which tends to be less congested than a two.four GHz network.
Adjusting software settings can also make a difference. Try lowering the resolution and refresh rate on the second laptop to reduce the amount of data being transmitted. This can help to improve performance, especially on older or less powerful laptops.
Closing unnecessary programs on both laptops can free up valuable system resources. Programs running in the background can consume processing power and memory, which can negatively impact performance.
Keeping your graphics drivers up to date is also important. Updated drivers often include performance improvements and bug fixes that can enhance the stability and responsiveness of your dual-monitor setup.
