Product Information

At a rough estimate, the ports on this device would require more than 76Gb/s of connection to the host computer to have all the necessary bandwidth, and it only has 10Gb/s. In whatever ways 10Gb/s is divided, it won’t adequately supply three 4K displays, six USB ports each requiring up to 10Gb/s, a Gigabit Ethernet port and the other less bandwidth-hungry items on here. Our immediate reaction to that information was to wonder why mounting six complicated cabling ports on this device was a better option than providing three DisplayPort and some inexpensive cable adapters for HDMI? Video Output: 1 x DisplayPort v1.1 ++ (Passive cables/adapters for HDMI or DVI conversion), 1 x HDMI v1.3

Q: How does my USB-C cable know what device I have and what functions the USB-C port on my device can perform?USB Ports extend the productivity capabilities of today’s thin laptops via one USB-C port, and five USB 3.0 ports, one of which is a 2.1A fast-charging port to power up a tablet or smartphone. Maximum Resolution Supported: Single Monitor - 2560 x 1600 @ 60Hz and Dual Monitors - 2048 x 1152 @ 60Hz Maximum Resolution Supported: Single Monitor: 4096 x 2160 @ 60Hz and Dual monitors: 4096 x 2160 @ 30Hz (macOS and Chrome OS devices only support a single display)

If you don’t have USB-C and are using the provided USB-A to USB-C cable that Kensington kindly includes, then a maximum of two 4K displays is possible. Ethernet Speed (Mbps): 10, 100, 1000 Actual Ethernet speeds may vary depending on, but not limited to, Internet bandwidth, Ethernet cables, network switches, and the hardware and firmware performance of the host computer. On the rear is a PSU power input, USB-C downlink from the computer, three each of DisplayPort 1.2 and HDMI 2.0, a Gigabit LAN port and four USB-A 3.1 Gen2 ports.And the other caveat to this hardware is the charging. The 60 watts provided isn’t enough power for charging the more powerful Ultrabook’s, like the 15-inch Apple MacBook Pro. of Monitors Supported: 2 (M1/M2 Base Chipset MacBook or USB-C Alt Mode laptop supports only a single external display)

As we might have predicted before opening the box, the glossy surfaces attract dust and fingerprints compared with the textured ones, that don’t. Your laptop or device must have a USB-C port. (Using an adapter on a USB 3.0 Type-A port will not work.) System requirements: USB-C host device must support Power Delivery. Power Delivery is not supported on USB-A host devices. Maximum resolution supported: single monitor - 2560 x 1600 @ 60Hz and dual monitors - 2048 x 1152 @ 60Hz The alternative display connecting method is DisplayLink, another technology designed to achieve multiple displays over limited bandwidth.

Don't have a Thunderbolt 3 port on your laptop? This docking station is a great option for USB-A and USB-C.

Maximum Resolution Supported: USB-C Alt Mode Device: Video 1: 3840 x 2160 @ 30Hz (@60Hz w/ DP1.4++) // Video 2 & 3: 3840 x 2160 @ 60Hz AND USB-C (non-Alt Mode) and USB-A Devices: Video 1: (n/a) // Video 2 & 3: 3840 x 2160 @ 60Hz
