How to choose the right KVM switch
Check resolution limits
Verify the maximum resolution each switch supports. The Sabrent Thunderbolt 4 KVM Switch handles 8K UHD, which suits users needing extreme clarity. Most other models, like the AV Access iDock-C20, cap at 1080p FHD or 4K UHD. If you use high-density displays, ensure the KVM matches your monitor's native resolution. Lower limits may result in blurred text or reduced workspace area. Always compare the listed resolution against your display specs to avoid performance bottlenecks.
Match refresh rates
Look at the refresh rate to ensure smooth motion. The AV Access iDock-C20 and iDock X20 both support 240Hz, ideal for fast-paced content. The Sabrent model offers 144Hz, while the TESmart 3-Monitor sticks to 60Hz. If your monitor supports high refresh rates, the KVM must match it. A lower rate on the switch will throttle your display. Check the specs sheet for the exact Hz value to guarantee compatibility with your visual needs.
Count computer ports
Determine how many systems you need to connect. The TESmart 4-Port USB-C KVM Dock and PVBCTCSID model support four computers. The Sabrent and AV Access iDock B23 handle three or two systems respectively. More inputs allow greater flexibility but increase desk clutter. Ensure the KVM has enough ports for all your devices. If you plan to add a laptop later, choose a model with spare inputs to avoid buying a new switch.
Verify monitor capacity
Check how many displays each unit can drive. The TJCXELE model supports four monitors across three computers. The TESmart 3-Monitor handles three displays, while many others limit you to two. Some models use MST to split signals, which may affect Mac compatibility. Ensure the KVM can output to your desired number of screens. If you need a triple setup, verify the specific model supports that configuration without requiring additional adapters.
Assess power delivery
Review the charging capabilities if you use laptops. The TESmert Dual Monitor KVM Switch provides 100W PD, suitable for high-power devices. The Sabrent model offers 60W charging. The AV Access iDock-C20 includes Power Delivery but with lower wattage. Ensure the KVM can charge your laptop while connected. If your laptop requires more power than the KVM provides, you will still need the original charger. Check the PD specs to avoid unexpected charging issues.
Frequently asked questions
Can I connect three computers to a single USB-C KVM switch?
Yes, several models support multiple host connections. The Sabrent Thunderbolt 4 KVM Switch handles three computers with high bandwidth. The TESmart 4-Port USB-C KVM Dock and PVBCTCSID 4 PC 2 Monitor KVM both manage four systems. These units allow you to switch peripherals and displays between multiple machines seamlessly.
Do these KVM switches support 8K resolution?
Some premium models support 8K UHD output. The Sabrent Thunderbolt 4 KVM Switch and AV Access iDock B23-S2 8K KVM Dock both handle 8K resolution. The Sabrent unit also supports 144Hz refresh rates at that resolution. Other models typically cap at 4K or 1080p depending on the port configuration.
Which USB-C KVM is best for Mac users?
Several options are optimized for macOS compatibility. The Sabrent Thunderbolt 4 KVM Switch is explicitly listed for Mac use. The PVBCTCSID 4 PC 2 Monitor KVM and TJCXELE USB-C 3 PC 4 Monitor KVM also support Mac systems. These units ensure stable display expansion and peripheral sharing across Apple devices.
Do I need DisplayLink drivers for these switches?
Certain models rely on DisplayLink technology for video output. The PVBCTCSID 4 PC 2 Monitor KVM and TJCXELE USB-C 3 PC 4 Monitor KVM feature DisplayLink support. The AV Access 4K Dual Monitor KVM Over Cat6 also uses DisplayLink. These drivers are often necessary to enable multi-monitor setups on specific operating systems.
Can I charge my laptop while using a KVM switch?
Many units include Power Delivery charging capabilities. The AV Access iDock-C20 and AV Access iDock X20 Dual USB-C KVM offer Power Delivery. The TESmert Dual Monitor 4K KVM Switch provides up to 100W PD. This feature allows you to charge connected laptops through the KVM hub instead of using separate chargers.
What is the maximum refresh rate supported by these switches?
Refresh rates vary by model and resolution. The AV Access iDock-C20 and AV Access iDock X20 Dual USB-C KVM support 240Hz. The Sabrent Thunderbolt 4 KVM Switch and TESmert USB-C KVM Switch for 2 Laptops offer 144Hz. The TESmert Dual Monitor 4K KVM Switch supports 120Hz. Higher rates suit fast-motion content.
Can I connect four monitors to a KVM switch?
Yes, specialized models support quad-display configurations. The TJCXELE USB-C 3 PC 4 Monitor KVM is designed for four displays across three computers. The CMSTEDCD Thunderbolt 4 KVM Dock supports three monitors for four computers. These units use DisplayLink or specific hub architectures to expand screen real estate beyond standard dual-monitor limits.
Do these switches work with Ethernet connections?
Many hubs include built-in Ethernet ports for wired networking. The AV Access iDock-C20, TESmart 3-Monitor 4K KVM Switch, and AV Access iDock B23-S2 8K KVM Dock all feature Ethernet connectivity. This allows you to maintain stable internet connections for both connected computers through the KVM hub without using separate network cables.
