Buying Guide
Key considerations when selecting a 4-computer KVM switch:
- Video bandwidth and resolution: If you work with high-resolution content, prioritize 4K@60Hz or 8K@60Hz support and verify that your monitor, cables, and devices are compatible.
- Monitors supported: Decide between single-monitor, dual-monitor, or more complex setups. Some models are designed for two displays, while others focus on a single screen.
- USB peripheral sharing: Check the number of USB 3.0 ports and compatibility with keyboards, mice, drives, and printers. USB-C data paths may be required for certain configurations.
- Switching method: Options include pushbuttons on the unit, remote control, or external controllers. Remote control can improve comfort in larger desks or multi-seat environments.
- EDID and compatibility: Look for adaptive EDID or EDID emulation features to ensure display compatibility across different PCs and operating systems.
- Power and cabling: Some switches require external power; ensure you have the right HDMI/DP cables and consider cable length for stability and signal integrity.
- Future-proofing: If you anticipate moving to higher resolutions or additional computers, consider devices with USB hub capacity and dual-monitor support to reduce later upgrades.
The selections above aim to balance high video quality with practical USB sharing and easy switching. Users should match a model to their desk space, monitor configuration, and the number of USB peripherals they intend to share across four computers.
