More Details on Our Top Picks

This dock stands out for its ability to connect two laptops to dual 4K monitors with high refresh rates, making it ideal for gaming and intensive work. Unlike the StarTech.com KVM, which is more compact and straightforward, this model offers a broader array of ports—including Ethernet and multiple USB connections—creating a more comprehensive workstation. However, its reliance on DP alt mode and MST support means compatibility issues may arise with certain Macs or ultrawide monitors. The tradeoff is a slightly larger size and complexity for far more connectivity options. This pick makes the most sense for users who need high-resolution, multi-monitor setups with extensive peripheral support and are willing to manage some setup complexity.
Pros:- Supports 4K resolution at high refresh rates, ideal for gaming and professional work
- Allows connection of two monitors and two laptops with easy switching

Cable Matters 20Gbps USB C Switch for 2 Computers, 140W PD, Up to 8K@30Hz on Windows, 4K@60Hz on macOS, Sharing One USB-C/Thunderbolt 4 Monitor or Dock
This switch offers impressive high-resolution support, including 8K at 30Hz, making it comparable to the Cable Matters 20Gbps model but with a focus on seamless monitor sharing between two computers. It differs from the AV Access dock by prioritizing simple monitor switching over multiple peripherals, with just two USB-C ports. Its 140W power delivery supports fast charging, making it suitable for professional setups. The main tradeoff is bandwidth limitation to 20 Gbps, which may restrict multi-display configurations or high-refresh-rate gaming. This device is best for users who need reliable high-res video sharing with quick switching, especially when simplicity and power delivery are key.
Pros:- Supports high-resolution 8K at 30Hz for stunning visuals

This compact KVM switch offers a straightforward solution for switching between two computers using USB-C or HDMI connections, with support for 4K at 60Hz. Compared to the high-capacity Cable Matters models, it emphasizes portability and ease of use, making it ideal for mobile professionals or hot desk environments. Its small size and included cables make setup quick, but it limits connections to just two devices and may encounter compatibility hiccups with mice with advanced features. Additionally, as it is bus-powered, it might not provide consistent power for all peripherals over extended use. This choice makes the most sense for users who prioritize a lightweight, plug-and-play device for basic high-res switching without complex setup.
Pros:- Supports 4K resolution at 60Hz for sharp, clear video

Unlike the SABRENT switch, which supports only two displays, this model offers an extra monitor for enhanced multitasking. Its seamless switch feature simplifies workflow, yet it requires driver installation and high-quality HDMI 2.1 cables to fully realize its 4K @ 60Hz potential. While it lacks Power Delivery, its broad OS compatibility and robust connectivity options make it a strong choice for professional setups that prioritize visuals and multitasking without charging needs.
Pros:- Supports three 4K@60Hz extended displays for detailed visuals

The SABRENT KVM Switch offers a compact solution for controlling two computers with two 4K@60Hz monitors and a single set of peripherals, making it ideal for limited desk space. Compared with the Thunderbolt 4 dock, which supports three monitors, this switch prioritizes simplicity and portability with its wall-mount option and included cables. Its Power Delivery up to 60W allows charging of connected devices, though it hinges on compatibility with DP Alt Mode-enabled USB-C hosts. The switch’s dual display modes enhance productivity but restrict users to just two screens, which may limit those needing extensive workspace. Its straightforward button switch simplifies operation, but setup depends heavily on compatible hardware.
Pros:- Supports dual 4K@60Hz displays for crisp visuals
- Single-button switching simplifies user operation
- Includes 60W Power Delivery for charging devices
- Compact design with wall-mount option enhances space efficiency
Cons:- Requires compatible USB-C hosts with DP Alt Mode, limiting device compatibility
