Have you ever wished you could use the beautiful, high-resolution screen of one laptop as a monitor for another? Maybe you need more screen real estate for a complex project, or your primary laptop’s display is damaged. Whatever the reason, connecting two laptops together is a handy trick that can boost your productivity and save the day.
While it might sound complicated, the process is often straightforward once you know which method to use. The right approach for you depends on the ports available on your laptops and what you’re hoping to achieve. Let’s look at the most common and effective ways to make this connection work.
Using an HDMI or DisplayPort Cable
This is often the first method people consider. If both of your laptops have an HDMI or DisplayPort output, you might think a simple cable will do the trick. However, most laptops only have video outputs, not inputs. This means you can send a signal to an external monitor, but you can’t receive one from another laptop.
To use this method, you need at least one laptop with a video input port, which is rare. Some specialized gaming or workstation laptops have this feature, often labeled as “HDMI-in.” If you’re one of the lucky few with this hardware, a direct cable connection is your easiest and highest-quality solution.
Leveraging Built-in Windows Projection Features
For most people, a wireless solution is the most practical. Windows has a fantastic built-in feature called “Projecting to this PC.” To set this up, go to Settings > System > Projecting to this PC on the laptop you want to use as the monitor. Set it to “Available everywhere” or “Always on.”
On your main laptop, press the Windows Key + P and select “Connect to a wireless display.” Your second laptop should appear in the list. Select it, and after a moment, its screen will mirror your primary display. This method is excellent for quick presentations or extending your workspace without any cables.
Exploring Third-Party Software Solutions
If you need more control and features, third-party software is a powerful option. Programs like SpaceDesk, Parsec, or even remote desktop tools can turn one laptop into a secondary display for another over your Wi-Fi network.
These applications typically require you to install a “host” program on the laptop acting as the monitor and a “client” on your main machine. They often provide low latency and high-quality video, making them feel almost as responsive as a physical monitor. This is a great choice for regular use.
Connecting a laptop to another laptop’s monitor is a versatile skill that can greatly enhance your workflow. Whether you choose the wireless convenience of Windows’ built-in tools or the robust performance of third-party software, you now have the knowledge to expand your digital workspace with the devices you already own.
