If you’ve plugged in one or more displays into your TS3 Plus dock and they aren’t showing up, please check to see if you are connected through the correct ports, using the correct cables and adapters, and using a computer that can support dual video streams out of a single Thunderbolt 3 port.
Check your video cables.
Due to various reasons some video cables are unable to connect to a display. Typical causes are physical wear and tear, an adapter that isn’t working, or too many adapters chained together to produce a strong signal.
If you are using any cable with connector pins, please ensure that these pins are in good condition and are not bent or broken.
To check to see if your cable is working, try to connect the display directly to a computer first.
Use ports that produce video.
On the TS3 Plus, the only ports that produce video are the Thunderbolt 3 ports and the DisplayPort. If you are trying to connect a monitor to a USB port, this will not be able to produce stable video signals.
Use ‘active’ adapters.
If you are using an adapter or cable to go from DisplayPort to HDMI, VGA, or DVI, please ensure that this is active. If you are unsure if you have an active cable or adapter rather than a passive one, please check the packaging or website and see if it is labeled specifically.
If you don’t already have one, we make one that works well with our docks – you can find a link here.
Dual video streams.
Some computers are equipped with Thunderbolt 3 ports which are not capable of producing two video streams out at the same time. If you are not able to get your second monitor to connect, an easy way to test if this is the case is to manually disconnect a working monitor to see if the second one pops up.
If your computer isn’t able to connect to two monitors through the same port, you can always connect a second monitor to your existing setup by connecting the second monitor directly to the computer.
If you have any questions about this or would like one of our support team members to walk you through these step by step, please contact our support department and we’d be happy to help you.
