Hey Karolisko, nice question—let’s walk through your options clearly based on your setup:

首先说你最想要的方案：只切换那台DP输入-only的显示器 #

This is totally doable, and honestly the simplest path forward. Here’s what you need:

• Grab a KVM switch that has two input ports matching your devices: one USB-C (for your work laptop) and one miniDP (for your home PC), plus a DP output port (for that single monitor you want to use at home).
• Just disconnect that DP-only monitor from your existing daisy chain (since it was the end of the chain anyway) and plug it straight into the KVM’s DP output. Leave the other monitor with DP in/out connected to your laptop’s USB-C via daisy chain for work use—no need to mess with that.
• Quick tip: If your work laptop uses USB-C for both video and charging, look for a KVM with PD power pass-through. That way when you switch back to your laptop, it’ll keep charging without needing a separate cable.

This is possible too, but requires a bit more checking for compatibility:

• You’ll need a KVM with USB-C + miniDP inputs, and a single DP output. Plug the KVM’s DP output into the monitor that has both DP in/out, then keep your second monitor daisy-chained to that first one’s DP output.
• Make sure two things: your home PC’s miniDP output supports DP 1.2 or higher (most modern GPUs do, but double-check your specs), and the KVM explicitly states it supports daisy-chained DP signals. If either is missing, you might run into resolution limits or no signal at all.

一些选购小提醒 #

• Always double-check port compatibility before buying the KVM—don’t assume a "universal" model will work with your exact USB-C/miniDP setup.
• If you want to use the same keyboard/mouse for both devices, pick a KVM with a built-in USB hub. It’ll let you switch both video and peripherals with one button (or even automatically, if you get a fancier model).
• Match the KVM’s supported resolution/refresh rate to your monitor’s specs—no point in buying a budget KVM that caps your display at 1080p if you have a 4K screen.

Bottom line: The single-monitor switch is your best bet here—it’s straightforward, has minimal compatibility risks, and exactly fits what you need for home use.
