Brand new dock plugged into brand new 16" MacBool Pro with Big Sur. I have two 32" Samsung monitors connected via hdmi cables (with the second using your supplied DisplayPort adapter).
If the computer goes to sleep, when I wake it up, the monitor plugged into HDMI blinks off for 2 seconds and on for 2 seconds and repeats forever. During this time nothing affects it. I’ve reseated cables, restarted the doc,
The only thing that works is a restart of the entire computer.
Thanks for posting!
We have an updated firmware for the TBT3-UDC3 dock that should resolve this HDMI flickering with the MacBook Pro 16". You can find a thread about it here:
If you’re able to
update the firmware with a USB-C or Thunderbolt 3 Windows computer, please let me know.
If not, no worries – we can send you a warranty replacement flashed with the latest firmware. Please contact us at
firstname.lastname@example.org with your Amazon Order ID and we’ll move forward from there.
Thanks for giving us a chance to help!
I saw this thread too! But I don’t have a windows computer. Only this MBP 16".
Understood! Please just reach out to us directly at
email@example.com and include your Amazon Order ID.
We’ll confirm purchase and warranty status and move forward from there with a replacement.

While the firmware update might help, I suggest you make sure both display outputs are set to 60Hz max in System Preferences>Displays. Any higher setting will cause issues on my system…
I bought this via Walmart online. ??
Thanks for the note,
@str11ngfello, in that case, please feel free to provide the Walmart order ID or invoice in the email to firstname.lastname@example.org.
