How to Choose Your KVM Switch
Check Port Compatibility
Your switch must match your monitor and computer inputs. The StarTech 4-Port DisplayPort KVM Switch uses DisplayPort for video, while the AV Access 4KEX100-KVM uses HDMI. If you use Thunderbolt 4 devices, the Sabrent Thunderbolt 4 KVM Switch is necessary. Ensure the physical connectors on the switch align with the cables on your peripherals. Mismatched ports will prevent connection regardless of other specifications. Always verify the input types before purchasing to avoid compatibility issues with your existing hardware setup.
Verify Resolution Support
Resolution determines image clarity and detail. Most listed switches support 4K UHD, which is standard for modern displays. However, the Sabrent Thunderbolt 4 KVM Switch and AV Access iDock B23 support 8K UHD for higher fidelity. The AV Access iDock-C20 is limited to 1080p FHD. If you have a high-resolution monitor, ensure the switch can output that resolution. Lower resolution support will result in a blurry or stretched image. Match the switch spec to your monitor's native resolution for the best visual experience.
Match Refresh Rates
Refresh rate affects motion smoothness, which is critical for gaming and fast-paced video. Many units cap at 60Hz, such as the StarTech 2-Port DP KVM. If you need higher speeds, the AV Access iDock B23 supports 165Hz, and the TESmert Dual Monitor supports 120Hz. The Sabrent model reaches 144Hz. Check the listed refresh rate to ensure it meets your needs. A low refresh rate on a high-speed monitor will bottleneck performance. Select a switch that matches or exceeds your monitor's maximum refresh rate.
Assess Power Delivery
Power Delivery allows the switch to charge your laptop while connected. The AV Access iDock M10 provides 100W PD, which is sufficient for most large laptops. The TESmert Dual Monitor 4K KVM Switch also offers 100W PD. The Sabrent model provides 60W, which may be slower for some devices. If you rely on the KVM for charging, verify the wattage output. Insufficient power may cause slow charging or battery drain. Choose a model with adequate PD if you plan to keep your laptop plugged in through the switch.
Confirm Number of Computers
The number of supported computers determines how many systems you can control. The StarTech 4-Port DisplayPort KVM Switch handles four computers. Most other listed models, like the TESmart 2-Monitor HDMI KVM, support two computers. The AV Access iDock B23 supports two computers with triple monitors. Ensure the switch supports the exact count of systems you own. Exceeding the limit is not possible, and using fewer inputs may waste potential. Select a model that matches your current setup and allows for minor future expansion.
Frequently asked questions
