Sharing a Desk Between a Mac and a Windows PC with a KVM Switch
Switching one keyboard, mouse, and set of monitors between a Mac and a Windows PC is a common reason to look at a KVM switch. The two platforms handle displays and USB-C video differently, so the same switch can behave differently depending on which computer is active.

Expect different behavior per platform
Manufacturer documentation often splits its instructions by operating system. TESmart describes its HDC202-P23 as delivering two displays from a Windows computer over one USB-C cable using MST, while a Mac needs two video-capable USB-C cables. Exact host compatibility still has to be checked, so treat this as an example of the pattern, not a rule for every Mac.
Count the video ports on the Mac
If a Mac needs two cables for two screens, it needs two ports that carry video, and the model itself must support two external displays. Apple lists display support per model and notes that resolution and refresh rate affect how many displays you can connect.
Plan for the shared keyboard
A shared keyboard sends the same keys to both machines. Decide whether you will remap Command and Control in each operating system, and check whether the hotkey the switch uses to change hosts conflicts with shortcuts you rely on.
Your pre-purchase checklist
- Note the exact Mac model and which of its ports carry video.
- Note the PC's video outputs, including whether its USB-C port supports video.
- Check how many external displays the Mac supports at your resolution and refresh rate.
- Read the switch manual's separate Mac and Windows instructions.
- Plan keyboard remapping for Command and Control.
- Confirm the full setup with the seller before ordering.
