As more people work remotely and pursue entertainment at home, a growing number of users want to combine efficient office work and high-quality entertainment in a single desktop space. In particular, the need for seamless switching between office and gaming/entertainment modes has become a key requirement for desk setup.
This blog post introduces a typical dual-machine + dual-monitor + single peripheral set desktop setup, using the TESmart HDC202-X24 Dual-Monitor KVM Switch to achieve one-click switching between office and entertainment modes, dual-screen linkage, and audio synchronization for an efficient and immersive experience.
Device Components and Connection Architecture
Host Devices

| Laptop (PC1) | MacBook Pro 14/16-inch (M1 Pro/M1 Max/M2 Pro/M2 Max) | Professional office work / Creative tasks |
Note: MacBook Air and basic MacBook Pro models (e.g., M1/M2) only support one external monitor and are not recommended for dual-screen KVM setups. Opt for models with at least two external display outputs (e.g., M1 Pro / M1 Max / M2 Pro and above).
Monitor Configuration
| Monitor | Input Requirement | Function |
| Dell U3225QE | HDMI | Primary screen for office work / multimedia enjoyment |
| Dell 2K Gaming Monitor | HDMI / DP | Secondary screen for multitasking / gaming expansion |
All monitors in this setup are HDMI input to avoid reliance on Type-C input and ensure better device compatibility.

MacBook Connection Guide (For Models Supporting Dual-Screen Output)
Correct Method for Dual-Screen Expansion:
-
Connection: Simply use one Type-C (Thunderbolt) cable to connect the MacBook to the PC1 input port on the KVM switch (USB-C with video input support);
-
Dual Monitor Connection: Connect two monitors to the KVM output ports (HDMI 1 and HDMI 2);
-
This setup will allow the MacBook to drive two monitors simultaneously, achieving dual-screen expansion.
This configuration requires no additional conversion cables or complex settings, as the KVM switch automatically handles video signal transmission. Users can easily switch between displays via the KVM's hotkeys.
