Can I Use My Personal Laptop as a Second Monitor for My Work Laptop?

Asked by TechnoWizard42
I'm exploring options for setting up a dual-monitor workspace with my work laptop. My company has strict policies against connecting unauthorized USB devices, so I'm looking for a safe method. I was thinking about using a video card to connect an HDMI cable from my work laptop's HDMI output to my personal laptop and using OBS on it as a second monitor. Would this even work? Would my work laptop recognize this as an external device? I want to steer clear of any policy violations, so if this setup isn't feasible, I'm considering just getting a dedicated monitor instead.

Nope, you canโ€™t use your personal laptop that way.

Actually, if your primary device runs Windows, thereโ€™s an app called SpaceDesk which lets you use another device as a second monitor over your network. Itโ€™s free for personal use and can connect with Android, iOS, or through a browser on your work laptop.

No, that wonโ€™t work. You can't connect them like that.

Unfortunately, it's highly unlikely that you can connect your personal laptop as a monitor because most laptops only have output ports, not input ports. So this setup won't work as you hope.

Honestly, your best bet is to just buy a standalone monitor. But if your company allows it, consider investing in a docking station that gives you more options for additional monitors.
