Can I Build a Gaming Desktop and Use My Laptop as the Display?
Asked by

I'm a college student who usually plays games in bed and don't have room for a desk. I'm considering building a desktop because I want to play demanding AAA games and have the option to upgrade components later. Gaming laptops with similar performance seem much more expensive and aren't as upgradeable. Since I can't use a TV, is there a practical way to connect the desktop to my laptop and use the laptop's screen and controls? I'm new to PC hardware, so I'd appreciate an explanation of how it would work and what limitations I should expect.

The most practical option is to run the games on the desktop and stream the video to your laptop using software such as Sunshine and Moonlight. The desktop handles the graphics, while the laptop acts as the screen and sends your keyboard or controller input back. You’ll want a strong home network, preferably wired Ethernet for the desktop and a good 5 GHz or 6 GHz Wi-Fi connection for the laptop. College or dorm networks may block or throttle this kind of traffic, so test the network before committing to the setup.

A gaming laptop would be simpler because it already includes the screen, keyboard, and battery, but a desktop can offer better performance per dollar and easier upgrades. The catch is that you still need some kind of display and input setup. If you build the desktop, consider budgeting for a small portable monitor, lap desk, or monitor arm rather than assuming the laptop can be used directly as the display.
MellowCedar42: That’s why I was looking at desktops. I want AAA-game performance without paying as much for a high-end laptop, and I like the idea of upgrading parts later.

A normal laptop usually cannot accept video input through its HDMI port. HDMI on laptops is generally output-only, so you can’t simply connect the desktop to the laptop and use it like a monitor. A USB capture card can technically display the desktop on the laptop, but it adds latency and is awkward for gaming. A portable USB-powered monitor beside your bed would be a cleaner alternative if you can find a comfortable way to position it.

MellowCedar42: Would streaming reduce the graphics requirements? I’m guessing the desktop still needs the graphics card to run the game, while the laptop mostly decodes the streamed video.
