Key Specs for Choosing a KVM
Check Resolution Limits
You must verify the maximum resolution each switch supports. Higher resolutions like 8K UHD require more bandwidth. The TESmart 8K HDMI DP KVM handles 8K for sharp images. The AV Access model offers 4K UHD over long distances. If you use standard 4K monitors, 4K support is sufficient. Check the resolution spec to ensure your displays are not downgraded. Match the switch output to your monitor's native resolution for the clearest image possible.
Match Refresh Rates
Refresh rate determines how smooth motion appears on screen. Gamers and video editors need high refresh rates like 144Hz. The TESmart 8K HDMI DP KVM supports 144Hz for fluid gameplay. The TESmart 4K KVM Switch 4 Monitors caps at 60Hz. If you prioritize speed over display count, choose the higher refresh option. Verify the spec matches your monitor's capabilities. A mismatch results in lower performance regardless of your hardware quality.
Count Your Monitors
The number of supported displays defines your workspace layout. Some switches handle dual monitors, while others support quad setups. The TJCXELE USB-C model supports four monitors for three PCs. The TESmart 4K KVM Switch 4 Monitors also handles four screens. The TESmart DP KVM Switch 3 Monitors fits three displays. Ensure the spec matches your physical desk setup. Exceeding the limit requires multiple switches or additional hardware.
Verify Port Types
Port compatibility is critical for connecting your devices. HDMI and DisplayPort are common video outputs. The TESmart 8K model uses both HDMI and DisplayPort. The TJCXELE model relies on USB-C for connectivity. The CMSTEDCD dock includes Thunderbolt 4 and HDMI. Check your computer and monitor ports before buying. Mismatched ports require adapters, which can reduce signal quality. Ensure the switch ports align with your existing cable inventory.
Check Computer Count
The number of computers determines how many sources you can switch between. Most models support two computers. The CMSTEDCD Thunderbolt 4 KVM Dock supports four computers. The TJCXELE model also handles three PCs. If you manage multiple desktops, verify the input count. Exceeding the limit prevents you from connecting all your machines. Select a model that matches your total number of workstations for seamless switching.
