Thunderbolt 3 work w/Samsung U28E590D 4k Monitor?

I have a brnad new 15 MacBook Pro. Will your Plugable Thunderbolt 3 Docking Station work with the Samsung U28E590D 28-Inch 4K UHD LED-Lit Monitor?

Hi Marc,

Thanks for posting! I have already sent my reply to your direct email sent to and have repeated the relevant portions below for the benefit of anyone else following this thread.

" Yes, our Thunderbolt 3 Docking Station ( is compatible with the Apple MacBook Pro Mid 2017 models.

To your monitor question, we have found that your particular Samsung display does not work properly when connected to our Thunderbolt 3 dock’s built-in DisplayPort output via a DisplayPort to DisplayPort cable.

That said, there are two alternatives to use your Samsung display with our dock. The first is to use the included DisplayPort to HDMI adapter to connect the Samsung display with an HDMI to HDMI cable. This will allow the monitor to work but will limit the monitor’s refresh rate to 30Hz.

The second is to use a USB-C to DisplayPort cable like our USBC-DP ( to connect your Samsung display to the second Thunderbolt 3 port of the docking station. I made a short video that shows how these two connection types work if you are curious ->… "

Thank you,

Plugable Technologies

Thanks Bob!

Follow up question: If I chose the 2nd option you referenced above and purchase/use your USBC-DP cable, what refresh rate will I achieve from the Samsung monitor?

Hi Marc,

Thanks for getting back, and you are of course most welcome for the help. To your follow-up question, when connecting the Samsung monitor to the dock’s second Thunderbolt 3 port via our USB-C to DisplayPort cable the Samsung monitor will be able to refresh at 60Hz.

Please let us know if you have any additional questions!


Hi Bob -

I have the above cable you listed, from amazon, and this same monitor - however no picture is coming through. Any tips?

The cable is plugged directly into the laptop, and then directly into the monitor.



Hi Josh,

Thanks for contacting us! Just to confirm, you are using the USB-C to DisplayPort cable I mentioned earlier, correct? (

One quick thing to double-check if you haven’t already is that the source input of the Samsung monitor is set correctly, because in some cases monitors with multiple inputs may not switch to the preferred automatically.

If that doesn’t help, the next step would be to get more information. If you would, please email us at with the specific brand and model number of laptop you are using with the cable and your Amazon Order ID number for the cable purchase and we will be happy to help.

Thank you,
