Dual PC DisplayPort KVM Switch

The J-Tech Digital JTECH-DKM21-8K is a DisplayPort 1.4 KVM switch that lets you control two computers from a single monitor, keyboard and mouse. It supports resolutions up to 8K at 60Hz and 4K at 240Hz for gaming, creative work and professional multitasking.

Host inputs and shared USB ports

Each computer connects through a DisplayPort and USB-C 3.0 host input, while four downstream USB 3.0 ports (three Type-A and one Type-C) share peripherals at up to 5Gbps. The unit includes the necessary DisplayPort and USB cables for a complete dual-system setup.

Switching method and signal bandwidth

You change the active system using the top-panel button or the included wired remote for instant switching. The switch passes up to 32.4Gbps bandwidth with 12-bit deep colour and HDR, delivering stable video transmission without added cooling or external power requirements.

Questions about this item

What resolution limit will I hit first if I run this KVM at its maximum bandwidth for hours?

The switch caps at 8K 60Hz or 4K 240Hz over its 32.4Gbps DisplayPort 1.4 link, so sustained use stays within those limits.

How much heat or fan noise does the unit produce when switching between two PCs all day?

The device has no fan and draws power from the connected computers, so it runs silently with negligible heat during continuous operation.

Which cables must I already own to connect both computers and the monitor?

You need two DisplayPort cables for video and two USB 3.0 host cables — one USB-A to USB-B and one USB-C to USB-C — to link both PCs.
