This switch supports 4K@60Hz, delivering crisp visuals while sharing peripherals across two devices. The package includes two HDMI cables and two USB cables for easy setup. It indicates the active PC via LED color, helping users track which system is in use. A limitation to note is that it is designed for two computers only and requires compatible HDMI displays.

Best for: Environments where sharing USB peripherals is important. This model toggles between two HDMI computers using a single USB keyboard and USB mouse on one HDMI monitor, with built-in USB ports for peripherals. It provides a clear indicator of the active computer. Limitations include basic Full HD performance and reliance on USB switching that may require accurate peripheral compatibility across devices.
HDMI KVM Switch 4K@60Hz 2 Port with USB 3.0
Best for: Users needing quick USB 3.0 peripheral sharing along with 4K visual fidelity. The device supports a couple of USB 3.0 ports to connect keyboards, mice, scanners, or USB drives, with two display inputs and a remote or button switching method. It notes that hotkey switching is not supported, which may affect power users who expect keyboard shortcuts for quick toggling. Choose this if you want solid USB 3.0 sharing and 4K compatibility in a compact kit.

Best for: Users needing high USB throughput to share multiple peripherals across two PCs. This model supports USB 3.0 ports in addition to HDMI, enabling smoother data transfer for devices such as printers and scanners.

Best for: Enthusiasts needing ultra-high refresh rates and multi-monitor sharing. This device targets setups with two monitors and dual PCs, offering 8K@60Hz or 4K@144Hz capabilities. It includes a wired controller and power adapter for stable operation. A caveat is that newer DP2.1 pathways may require compatible cables and monitors to realize full 8K/144Hz potential, so verify display chain compatibility before purchase.
Buying Guide: Key Purchase Considerations
What should you check before buying a 2-port HDMI KVM switch? Consider the following:
- Video resolution and refresh rate: Ensure the switch supports your target display (4K@60Hz is common; higher rates may need DP or HDMI capabilities).
- USB sharing: Determine how many USB peripherals you need to share. Some models include multiple USB 3.0 ports for fast devices like printers or scanners.
- Switching method: Choose between button, remote, or hotkey switching. Some models do not support hotkeys, which can affect workflow.
- Indicators and EDID handling: LED indicators help you know which PC is active. EDID compatibility ensures the display maintains correct resolution when switching.
- Compatibility: Verify compatibility with your computers (Windows, macOS, Linux), and peripherals (keyboard, mouse, printers, game controllers).
- Cable requirements: Some kits include cables; others require you to purchase HDMI and USB cables separately.
