Displayport

A KVM black screen is usually a signal-path, bandwidth, wake, or EDID problem. Use this order to isolate the fault without replacing everything.

Choose HKS202-P23 for a dual-4K60 HDMI desk or DKS202-M24 for DisplayPort and high refresh. Compare ports, cables, EDID, and buyer fit.

The DKS202-M24 switches two DisplayPort PCs across two monitors with EDID and high-refresh support. Check the six-cable layout and laptop limits first.

UGREEN's 55851 switches two DisplayPort computers across two monitors and four USB devices, but it lacks EDID, hotkeys, charging, and included DP cables.

The right dual-monitor KVM depends on your ports, refresh rate, and whether you are switching desktops, laptops, or one of each. These are sensible 2026 picks.
