About this deal

System Requirements: USB-C host device must support Power Delivery. Power Delivery is not supported on USB-A host devices without the use of the optional 60W power splitter (K38310) Compatibility: Windows 7 or above, macOS 10.13 or above, Chrome OS 44 or above, iPadOS 13.4 or above, Android 9 or later

How well this works for any specific user is entirely dependent on many factors, such as the laptop host hardware, the resolutions of the monitors and the amount of motion on the displays.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. Another slightly odd choice is that the top is slightly recessed, creating a tray of sorts for small change, or whatever. They also made some curious choices about the texturing of this case, where the top, bottom rear and sides have a matt appearance, but the front is high gloss. There have been some instances of DisplayLink devices with a yellow "!" in device manager, and opening the properties shows that they have an error code 43. This is usually due to a driver fault. To fix this error we recommend trying the following steps: Overall, the compromises made to achieve triple displays are too great, and most users would be better with a dual-screen option and plugging the third display directly into the laptop to reduce the bandwidth overhead.

Compatibility: Compatible with Windows 7 or above laptops with a USB-C port supporting DisplayPort Alt Mode and Power Delivery Maximum Resolution Supported: Single Monitor - 2560 x 1600 @ 60Hz and Dual Monitors - 2048 x 1152 @ 60Hz Update the computer's BIOS/UEFI with the appropriate file from your system/motherboard manufacturer. Best For: Windows OS (7 or above) laptop with a USB-C port supporting DisplayPort Alt Mode and Power Delivery Your device must be running Windows 10, 8.1 or Mac OS X Yosemite (10.10) or later, or Chrome OS (R53 or above).

The obvious conclusion is that this isn’t practical, or at least some significant compromises are required in what you can realistically connect and how it might work. System requirements: USB-C host device must support Power Delivery. Power Delivery is not supported on USB 3.0 host devices without the use of the optional 60W power splitter (K38310NA)

As we might have predicted before opening the box, the glossy surfaces attract dust and fingerprints compared with the textured ones, that don’t. Passive cables and adapters do not have such a conversion chip built in. Instead they rely on the source to do the conversion. Unless the source has the ability to output analogue over DisplayPort or HDMI then an active adapter is required for VGA output. What is the difference between active and passive?Active cables and adapters contain have their own built in chip which converts the video signal from say DisplayPort to HDMI, they also convert the digital DisplayPort or HDMI signal to the analogue VGA signal

Plenty of connectivity, but practical bandwidth limits

There have been some instances of DisplayLink devices with a yellow "!" in device manager, and opening the properties shows that they have an error code 10. This has been either due to a faulty device, or due to a device with auto install (which are not supported as detailed below) and the DisplayLink video driver is trying to talk to the wrong interface putting it into an error state. Some USB 3.0 enabled PCs can exhibit issues which can be resolved by connecting your product through an external mains powered USB hub

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. 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? 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. If you have Windows 7 installed see thisarticle to obtain the latest USB 3.0 host controller driver Uses the power supply from SD4700P, SD4750P, SD4780P or SD4900P to provide power to USB-A enabled laptops that support 20V/85W. *The power splitter is optimized to provide rapid charging at 60W and is not intended for use with laptops under 20V/60W.*Laptop Cable provides ideal length for various connection needs and accommodates multiple power tips to be tethered to the cable at one time via four power adapter retention rings –providing a convenient solution for mixed deployments or shared workspaces Your laptop or device must have a USB-C port. (Using an adapter on a USB 3.0 Type-A port will not work.) Best for: Highly mobile USB-C devices, requiring additional ports for accessories, as well as monitors and projectors that support up to 4K
