Dual-monitor KVM for two computers

This KVM switch connects two computers or laptops to a single keyboard, mouse and dual DisplayPort monitors. Two integrated USB 3.0 hub ports add extra peripheral connections. It suits IT specialists, multi-tasking professionals and home-office users who need to control both systems from one desk.

DisplayPort 1.4 sustained resolutions

The switch handles 8K at 30 Hz, 4K at 144 Hz and 4K at 240 Hz in 32:9 format, plus 2560x1440 at 144 Hz and lower modes. Actual output depends on the graphics cards, monitors, cables and adapters used together. No compression or downscaling is applied by the unit itself.

Cables, ports and OS before ordering

Each computer needs two DisplayPort 1.4 outputs and a USB 3.0 connection for keyboard, mouse and hub traffic. Verify that your monitors accept the target resolution and refresh rate over DisplayPort. The switch supports Windows, Linux and macOS, plus keyboard-less devices such as DVR or NVR units. Audio switching for headphone, microphone and speaker is included.

Questions about this item

Does the 622DP-4 run hot or draw much power when I leave both computers on all day?

The unit is a passive DisplayPort 1.4 switch with no internal fan; it draws only the small standby current needed to keep the USB 3.0 hub ports alive, so heat and power draw stay negligible during continuous use.

What cables must I already have to connect two PCs and dual monitors to this switch?

Each computer needs two DisplayPort 1.4 cables and one USB 3.0 upstream cable; the console side requires two DisplayPort 1.4 monitor cables plus keyboard, mouse and any USB 3.0 peripherals you want to share.

Will my older 2560 x 1440 144 Hz monitors work at full refresh through the 622DP-4?

Yes — the switch lists 2560 x 1440 at 144 Hz among its supported modes, so those monitors will run at their native refresh rate provided the graphics cards and cables also meet DisplayPort 1.4 requirements.
