Desk drama: no-touch switching
Two computers, one monitor, zero fiddling – Alex Plescan
He built the dream one-button desk setup, and the internet instantly argued about the price
TLDR: Alex built a keyboard-only way to swap one monitor and accessories between a work laptop and home desktop, aiming for a seamless desk setup with no cable swapping. Commenters called it both the dream and a splurge, arguing over whether this is clever perfection or just an expensive version of a basic switch box.
A work-from-home fantasy just dropped: one monitor, one keyboard, one mouse, and two computers that swap places without the usual cable chaos. Alex Plescan says he finally solved the daily desk annoyance by buying a monitor with a built-in switcher and then making it change sources from the keyboard, so he can jump from Mac work mode to Linux play mode without even reaching for the screen. For anyone who has ever crawled behind a monitor like a goblin hunting cables, the appeal is obvious.
But the comments? Oh, they were not going to let this become a simple victory lap. The biggest reaction was basically: love the idea, hate the price. One of the top replies dryly summed it up as "zero fiddling" but with a "substantial financial outlay," which is internet-speak for cool trick, rich guy. Another camp came in swinging with the classic blunt-force question: why not just buy a normal switch box and call it a day? That kicked off the mini-drama—was this elegant genius, or a very expensive way to avoid pressing one extra button?
Still, plenty of readers were impressed. Some admitted they didn’t even know monitors could be controlled this way, while others chimed in with their own Frankenstein desk setups involving scripts, shared mouse software, and enough custom tinkering to make the original post look almost tidy. Even the jokes landed: Alex apologizing to the wall for the ugly gamer styling and messy cables became an instant mood. In the end, the crowd seemed united on one thing: everyone wants this seamless setup, they just wish it didn’t cost so much to escape the fiddling.
Key Points
- •The article describes a setup where a Mac laptop and Linux desktop share one monitor, keyboard, mouse, and audio peripherals.
- •The setup relies on an MSI MPG 321URX monitor with built-in KVM, allowing USB peripherals to follow the active video input.
- •The MacBook is connected over USB-C and the Linux desktop over DisplayPort.
- •The monitor input is switched programmatically using DDC commands sent over the display connection rather than using physical monitor controls.
- •On macOS with Apple Silicon, the author uses m1ddc and Hammerspoon to bind monitor input switching to a keyboard shortcut.
