J-Tech Digital JTECH-DKM21-8K (DisplayPort / 2 Computers / 8K@60Hz / 4 USB 3.0 Ports) Review
J-Tech Digital JTECH-DKM21-8K 2x1 DisplayPort 1.4 KVM switch lets two computers share one monitor, keyboard and mouse with 8K@60Hz / 4K@240Hz output and a 4-port USB 3.0 (5Gbps) hub with 3 USB-A and 1 USB-C ports.
If you run two PCs off a single high-refresh or high-resolution monitor, the DKM21-8K is a straightforward way to stop swapping cables. It passes DisplayPort 1.4 through cleanly enough for 4K at 240Hz or full 8K at 60Hz, and the USB 3.0 hub (with a USB-C port included) switches your keyboard, mouse, and any other USB peripherals along with the display. Switching is done from the front panel or the included wired remote, so there's no software to install.
Overview
The JTECH-DKM21-8K is a 2-computer, 1-monitor DisplayPort 1.4 KVM switch built for desks running two machines against a single high-end display. It carries full 8K@60Hz / 4K@240Hz bandwidth and bundles a 4-port USB 3.0 hub (3x USB-A, 1x USB-C) so keyboard, mouse, and other peripherals switch along with the video signal.
Switching
Source selection is handled from a front-panel button or the included wired remote control, letting you flip between the two connected computers without reaching behind the desk.
