KVM Hardware Solution for Different Types of Computers

Optimizing KVM Hardware Solutions for Diverse Computer Setups

Introduction

In modern multi-device environments, seamless switching between different computers—such as high-performance gaming rigs and portable laptops—can significantly enhance productivity and user experience. This article explores a professional hardware solution approach for integrating multiple systems, including a high-end PC equipped with a GeForce RTX 4090 and a MacBook Air M4, with a shared display, input devices, and licensing hardware. The goal is to facilitate effortless switching, maintain high-quality video output, and ensure uninterrupted device charging.

Current Scenario

Presently, the user operates a standard home PC connected to a 42-inch LG C2 OLED television via HDMI 2.1, utilizing a USB-C keyboard and mouse, along with a USB-A license dongle for DaVinci Resolve Studio. The setup allows for basic connectivity but requires manual cable swapping when switching between the PC and a MacBook Air M2 or M4, which introduces inconvenience and potential wear on ports and cables.

Background and Requirements

The user’s workflow involves periodic use of MacBook Air M2 and M4 models provided by their employer for video processing and editing tasks. The desired setup seeks to:

Connect both a powerful gaming/work PC and a MacBook Air to the same display
Use a single set of input devices (keyboard and mouse) and a license dongle for efficiency
Achieve high-quality 4K output at 120Hz for smooth visuals
Enable charging of the MacBook Air during operation without additional cables or disconnects
Minimize cable management complexity and maximize device compatibility

Proposed Hardware Solution

To address these objectives, a professional-grade KVM (Keyboard, Video, Mouse) switch combined with supporting hardware is recommended. This approach ensures signal integrity, user convenience, and compatibility across different device types.

High-Performance KVM Switch
