The Startech.com Thunderbolt 4/USB4 Quad Display Dock is armed with 16 ports, which means it can offer users a great deal of flexibility when it comes to adding external displays. Windows users will find this docking station the most appealing because they will be able to run four external displays via the dedicated high-end display ports and enjoy high refresh rates.
While there may be other docking stations that offer support for four external displays, this one stands out because of the combination of its features and price.
Specs and Features
The combination of ports that you will find here is extremely high-end for the main part, as it includes 2.5Gb Ethernet and 2 DisplayPort 1.4 ports, one upstream Thunderbolt 4 port and 2 HDMI 2.1 ports. But, there are also some old-school options that can be disappointing, as it boasts six USB-A ports, but there is only one USB-C port. There is also no downstream Thunderbolt 4 port, which can be a concern for someone who wants to connect as many external displays as possible.
As for Mac users, they will certainly be able to enjoy dual-display port flexibility, but they are likely to not use the four port options. Therefore, they might not find the docking station as useful as Windows users. Nonetheless, the addition of 2.5Gbs Ethernet is certainly a smart move because it future proofs the docking station for faster wired networks.
Another perk that Startech.com has added to its docking station is the UHS-II SD Card reader (320MBps), which is significantly faster than the UHS-I SD card reader. There is not much you can get in terms of device charging because the highest rated USB port is capable of giving about 7.5W power. But, you can charge the laptop through the 180W power supply.
Multiple Display Options
The four display ports are all top-end, which include two DisplayPort 1.4 and two HDMI 2.1, both of which are capable of supporting a single 8K (7680 x 4320 pixel) monitor at a refresh rate of 60Hz. As far as Macs are concerned, they can get the highest resolution at 6K/60Hz (6144 x 3456). Macs may not be able to get a lot of flexibility, but Windows users will certainly be able to add more monitors and external displays.
Design and Build
The dock is available in a dark gray case and the ports have been marked properly, both on the front and the back. The 7.5W USB 2.0 port is at the front, which makes sense, as you might want to use it for charging your phone. The card and audio readers are also on the front, which makes them easy to use.
On the rear, you will find four extra USB-A ports. The front mounted power button is also convenient because it makes it easy to preserve the laptop’s battery life, since you do not have to unhook it repeatedly.
The Verdict
In terms of specs, the Startech.com Thunderbolt 4/USB4 Quad Display Dock manages to beat its competition because it offers quad-display support at the highest refresh rates.
