You have two computers on your desk but only one set of peripherals and monitors. Switching between them means crawling under the desk to swap cables or juggling multiple keyboards and mice. A DisplayPort KVM switch solves this neatly: it lets you control both machines with a single keyboard, mouse, and up to three monitors. Whether you are a video editor, a programmer, or a home office worker, the right KVM can streamline your workflow and free up space. This guide covers the best DisplayPort KVM switches for 2026, focusing on models from UGREEN and JCYMELE that handle dual and triple monitor setups.

Buying Guide: How to Choose the Best DisplayPort KVM Switch
Resolution and Refresh Rate
DisplayPort KVM switches support resolutions from 4K up to 8K at 60 Hz. If you use high-refresh-rate monitors for gaming or video work, look for a switch that handles 4K at 144 Hz or 240 Hz. The UGREEN models offer 8K@60Hz and 4K@240Hz, while the JCYMELE reaches 4K@144Hz. Check that your monitors and cables are compatible with the desired resolution.
For most professionals, 4K@60Hz is sufficient, but creative tasks benefit from higher refresh rates. Always use certified DisplayPort 1.4 cables under 2 meters to avoid signal degradation. For more on high-resolution setups, see our best 4K KVM switch article.
Number of Monitors and Ports
Decide how many monitors you need to share. Dual monitor switches are common, but triple monitor switches like the UGREEN 3-monitor model let you extend your workspace across three screens. Ensure your computers have enough DisplayPort outputs: each PC must have two or three DP ports plus a USB-A port for the KVM connection.
Also check that the KVM supports both extended and mirror modes. Extended mode is ideal for multitasking, while mirror mode works well for presentations. If you work with a Mac and PC, read our best KVM switch for Mac and PC guide.
USB Connectivity and Data Speed
A good KVM switch includes USB 3.0 ports (5 Gbps) for sharing peripherals like keyboards, mice, webcams, and storage drives. The UGREEN and JCYMELE switches offer four USB 3.0 ports, with some including a USB-C port. Ensure the switch provides stable power via an external adapter, especially when using high-power devices.
If you need to share a printer or external hard drive, USB 3.0 speed is sufficient. For more on home office setups, check our best KVM switch for home office recommendations.
Switching Methods and Ease of Use
Most DisplayPort KVM switches offer button switching and a remote desktop controller. Hotkey switching is not supported on these models, so plan to place the controller within easy reach. Plug-and-play installation without drivers is standard. The remote controller keeps your desk tidy and lets you hide the main switch.
Some users prefer a simple push button; others like a desktop switch. Both UGREEN and JCYMELE include a remote controller. If you need a dock with more ports, see our best Thunderbolt dock for Mac guide.
Final Thoughts
Choosing the best DisplayPort KVM switch depends on your monitor count and resolution needs. For a reliable dual monitor setup with 8K support, the UGREEN 8K@60Hz Displayport KVM Switch 2 Monitors 2 offers excellent build quality and USB 3.0 ports. If you need a triple monitor solution for demanding workflows, the UGREEN 8K@60Hz HDMI Displayport KVM Switch 3 provides both DisplayPort and HDMI inputs with high refresh rates. For a budget-friendly dual monitor option, the 4K@144Hz KVM Switch 2 Monitors 2 Computers Display from JCYMELE delivers solid performance at a lower price point. Whichever you pick, you will enjoy a cleaner desk and seamless computer switching.
Frequently Asked Questions
Can I use a DisplayPort KVM switch with a laptop that only has USB-C ports?
Yes, but you will need a USB-C to USB-A OTG adapter plus the included USB-A cable to connect the KVM’s USB port. For video, your laptop must have a DisplayPort output via USB-C (Alt Mode) or you may need an adapter. Check compatibility before buying.
Does a DisplayPort KVM switch support extended and mirror modes?
Yes, the models reviewed support both extended and mirror modes. Extended mode lets you drag windows between monitors, while mirror mode duplicates the same image on all screens. Ensure your computer’s graphics card can drive the number of monitors you connect.
Do I need an external power supply for these KVM switches?
Yes, all three switches require a 12V DC power adapter to operate reliably. The external power ensures stable USB data transfer and prevents signal loss. The power adapter is included in the package.
What is the difference between DisplayPort and HDMI KVM switches?
DisplayPort KVM switches are designed for monitors with DisplayPort inputs, offering higher bandwidth for resolutions like 8K and high refresh rates. HDMI switches are more common for consumer electronics. Some models, like the UGREEN triple monitor switch, include both DisplayPort and HDMI ports for mixed setups.
