I have been having this issue since 2020 with two different machines and and several different OSs. All the issues I've had with this dock have persisted through each of my hardware changes and troubleshooting attempts. Admittedly, most of my issues documented here are from when I used a Mac as my host machine. I have also encountered issues with the dock and my Windows machine, but I chalk that up to issues with Razer/Microsoft and not the dock itself (I can elaborate on this if anyone would like, but am omitting for now).
Additionally, it's worth noting that I did not experience any issues with this dock in 2018-2019. At that time I was using a MacBook Pro (16-inch, 2016) running macOS Sierra as the host machine, two monitors that were the same make and model (
Dell Flat Panel Monitor E2417H), and a wired USB headset.

Issues:
Monitor Wake Issues
When host machine is sleeping and then wakes up, only the monitor connected to the extra Thunderbolt 3 Port via DP to USBC cable wakes, and the monitor connected to the Mini Display Port remains dark (does not detect any input from dock).
What Resolved the Issue
- unplug the mini display port from dock, and plug back in
- unplug thunderbolt 3 cable from host machine, and plug back in
- Disconnect monitor plugged into dock's extra Thunderbolt 3 port, and connect it directly to host machine (with other monitor still connected to the dock via Mini DP, and the dock still connected to host machine)
What Did Not Resolve the Issue
- Reboot host machine (works sometimes, does not work others)
- Connect the dock to host machine using one of the host machine's other Thunderbolt Ports (tried all 4)
- Turn the monitor that did not wake off and then back on
- replace original thunderbolt 3 cable connecting dock and host machine with generic brand thunderbolt 3 cable
- replace original thunderbolt 3 cable connecting dock and host machine with high quality thunderbolt 3 cable
- replace original DP to Mini DP cable connecting Dell monitor and Dock with new DP to Mini DP cable
- Change Monitor Configuration (ie. connect Acer monitor to dock's Mini DP port using DP to Mini DP cable, connect Dell monitor to dock's extra Thunderbolt 3 port using DP to USBC cable)
- The monitor connected via Mini Display Port continues to remain dark when host machine wakes.
- Change host machine configuration (ie. connect host machine to extra Thunderbolt 3 port, and connect Monitor to extra Thunderbolt 3 Port
- Update host machine to latest OS
- Update host machine's graphics drivers with latest
- Install OWC Dock Ejector software
- Update Dock's Firmware
- N/A, from what I could find this is not possible.
- use a different OWC Thunderbolt 3 Dock (slightly newer model)
Have yet to try
- Connect both monitors to a USBC splitter/dongle, and connect that dongle to the extra Thunderbolt 3 port on the dock
- Connect Monitor to dock using HDMI to Mini DP
- Connect Monitor to dock using VGA to Mini DP
- Connect Monitor to dock using DVI to Mini DP
Peripheral Issues
When on a call (Slack/Discord) using Logitech G377 Headset, my voice becomes staticy/robot-like, or cuts out entirely for participants.
When on a call (Discord) using Razer Man O'War, participant's voices will suddenly become staticy and their volume will increase to unpleasant levels.
What Resolved the Issue
- Use a wired USB headset
- Use a wired audio jack headset
- Plug wireless headset receiver directly into host machine
What Did Not Resolve the Issue
- update Logitech G377 Headset's firmware
- update Razer Man O'War Headset's firmware
- Reboot Slack/Discord (works initially, but issue comes back shortly)
- Reboot host machine (works initially, but issue comes back shortly)
- Move wireless headset receiver to different USB 3.1 port on the dock (tried all ports)
Network Issues
Wired network connectivity will drop for short periods of time at seemingly random intervals. Not a big issue when working, but very big issue when streaming or gaming.
I could not find a solution for this issue that wasn't just not using the ethernet port and relying on the host machines wifi adaptor.
What Did Not Resolve the Issue
- use a different ethernet cable
Theories
The theories I have of what the issue might be are as follows:
- Not enough power going to the dock
- this would explain the network drops and why peripherals that require a large amount of power (monitor, wireless headset) have a spotty connection.
- there's a bug with the dock where it does not wake monitors connected via Mini DP if a monitor is connected using the extra Thunderbolt 3 port
- this doesn't really make sense since this configuration worked seamlessly for me back in 2018-2019.
- dock gets confused with two different makes and models of monitors
- my issues began when I started working from home full time using two different monitors. I never had issues using two monitors of the same make and model (Dell Flat Panel Monitor E2417H)
- I could be using the wrong Display port cables
- the OWC Dock manual states the Mini DP port connection supports DisplayPort 1.2. When I replaced my cables, I specifically looked for DP to MiniDP 1.2, but could only find 1.4. However, I started out using the cables I had used when my dock was working properly in 2018-2019.
- there's a bug in macOS where it does not wake monitors correctly that are connected to a splitter/dongle/dock
- this would make sense since my issues only started with macOS High Sierra, however, I'd expect to see more questions on forums related to my issue if this was the case.
Conclusion
The only way I've found to be able to use this dock today is to, essentially, not use the dock. The main pieces of equipment that I use on a daily basis are 2 monitors, a wireless headset, a mouse, and a keyboard. My mouse and keyboard connect via bluetooth, so there's really only 3 things that I need plugged into the dock. However, in order for both monitors to reliably wake with the host machine, and my headset to not cut out, I need to plug my wireless headset receiver and one monitor directly into the host machine. An added perk would be if my network speed increased due to a wired connection, but I don't even get that from this dock since the network cuts in and out. Currently, this dock saves me one Thunderbolt 3 port since the charge through does work, and it can only seem to handle one monitor connected to it.
