I tested the AOOCOO USB-C KVM Switch with a MacBook Pro and a Dell XPS laptop over two weeks. The 100W Power Delivery actually delivered around 85W to my MacBook after accounting for power loss through the switch. This kept my laptop charged during heavy workloads without needing a separate power cable.
The metal construction immediately impressed me. Unlike plastic KVMs that slide around your desk, this one stays put and dissipates heat effectively. After eight hours of continuous use, the chassis remained only slightly warm to the touch.
Switching between systems takes about three seconds using either the button on the unit or the wired remote controller. The remote has a small but useful indicator light showing which computer is currently active. This seems minor until you have accidentally typed into the wrong system during a video call.

Smart power management cuts power to USB peripherals when the connected computer shuts down. This saved me from the annoying dance of reconnecting my wireless keyboard and mouse every morning. The four USB 3.0 ports delivered full 5Gbps speeds during file transfers to external SSDs.

KVM Switch Buying Guide: What to Look For
Choosing the right KVM switch requires understanding several key specifications. This guide explains what matters most for different use cases and helps you avoid common purchasing mistakes.
Port Compatibility: HDMI vs DisplayPort vs USB-C
Your existing monitor connections dictate which KVM type you need. Most modern monitors use HDMI, making HDMI KVMs the safest default choice. DisplayPort KVMs suit high refresh rate gaming monitors and professional displays. USB-C KVMs work best with modern laptops that use USB-C for both video and data.
Check your computer outputs before purchasing. Some KVMs require specific port combinations that might not match your setup. The CMSTEDCD HDMI+DisplayPort model, for example, requires native ports on your computers and rejects adapter cables entirely.
Resolution and Refresh Rate Requirements
Match your KVM to your monitor capabilities. Basic 1080p@60Hz needs require only budget KVMs. 4K@60Hz support appears in most modern switches above $30. Gaming at 144Hz or 240Hz requires specific high-refresh KVMs like the IOGEAR or UGREEN DisplayPort models.
Future-proofing considerations matter if you plan monitor upgrades. An 8K-capable KVM like the CMSTEDCD 8K model handles next-generation displays without replacement.
USB Hub Capabilities
USB port quantity and speed vary significantly between models. Basic KVMs offer two USB 2.0 ports sufficient for keyboard and mouse only. USB 3.0 hubs at 5Gbps speeds handle external drives, webcams, and other peripherals. Premium models include four or more USB ports with USB-C connectivity.
Consider your peripheral needs beyond keyboard and mouse. Content creators sharing cameras and audio interfaces need more ports than office workers using only basic input devices.
Switching Methods: Hotkey vs Button vs Remote
How you switch between computers affects daily workflow efficiency. Hotkey switching uses keyboard combinations for instant changes without reaching for hardware. Button switching requires pressing physical buttons on the KVM unit. Wired remotes let you position the switch conveniently.
None of the budget KVMs in this roundup include hotkey switching. This feature appears primarily in enterprise-grade switches costing significantly more. Most users adapt quickly to button or remote switching after a few days of use.
EDID Emulation Explained
EDID (Extended Display Identification Data) tells your computer what capabilities your monitor supports. Without EDID emulation, your computer re-detects the monitor each time you switch, causing delays and potential window rearrangement.
The Hearvo includes adaptive EDID that partially addresses this issue. True EDID emulation requires more expensive hardware. For most users, the brief delay during switching represents an acceptable trade-off for lower costs.
Power Delivery for Laptops
USB-C KVMs with Power Delivery (PD) can charge laptops while handling video and data. The AOOCOO’s 100W PD represents the highest capability in this roundup, though actual delivery is around 85W after power losses.
Check your laptop’s power requirements before purchasing. A 100W PD KVM cannot fully charge laptops requiring more power, like some gaming laptops or 16-inch MacBook Pros under heavy load.
Frequently Asked Questions
Are KVM switches still used?
Yes, KVM switches remain essential tools for anyone managing multiple computers. Remote work trends have actually increased demand as more people maintain separate work and personal computers at home. Modern USB-C KVMs with Power Delivery charging represent significant upgrades over older models.
