Two-computer DisplayPort KVM

The Monoprice 142645 Blackbird lets you operate two computers from one keyboard, mouse and 4K display. It handles DisplayPort 1.4 and HDMI 2.0 signals with HDCP 2.2 content protection. USB 3.0 peripheral ports allow shared printers or storage devices to stay connected while you switch sources.

Sustained 4K@60Hz throughput

Bandwidth reaches 32.4Gbps over DisplayPort and 18Gbps over HDMI, keeping full 4K@60Hz resolution stable during long sessions. HDR and Deep Color are supported at 16-bits per channel on DisplayPort and 12-bits per channel on HDMI. The switch maintains YCbCr 4:4:4 colour fidelity without dropping frames under continuous load.

Metal chassis with front-panel buttons

A sturdy enclosure resists movement when cables are tugged during daily switching. Push-button and IR remote control give instant source selection without software latency. The included 5V 3A power adapter ensures reliable operation, and USB 3.0 cables for both host connections are supplied in the box.

Questions about this item

Does the Monoprice 142645 KVM switch generate noticeable heat or fan noise when left powered on all day?

The unit is passively cooled with no internal fan, so it runs silently; the external 5 VDC 3A power adapter handles all power conversion and remains cool under normal 4K@60Hz operation.

Which cables must I already own to connect two computers and one monitor to this 2×1 DisplayPort 1.4 KVM?

You need two DisplayPort 1.4 cables for the video links from each PC to the switch, one DisplayPort cable from the switch to the monitor, and two USB 3.0 Type-A to Type-B cables for keyboard and mouse — none are included.

Will the switch pass 4K@60Hz HDR from a newer GPU while my older 1080p 60 Hz panel stays connected?

Yes, the switch negotiates EDID per port; it delivers up to 32.4 Gbps DisplayPort 1.4 with YCbCr 4:4:4 and HDR to a capable monitor, while an older 1080p display simply receives its native resolution without downscaling the other port.
