Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.
The monitor lag / mouse lag sounds like the system may be having trouble keeping up with the resource demands of the display. Were you using this display with your system prior to purchasing our TBT3-UDZ dock without issue?
I do not believe the display itself would be the issue for the kinds of problems described. I assume this is happening in macOS? If so, what version are you running? Catalina 10.15.x or Big Sur 11.x?
What is the exact model of your monitor? Also, what model Mac are you running? IE MacBook Pro 15" 2019, etc.
You’d have to see if LG offers any updated firmware for your display, but I don’t expect there to be any firmware updates available/required.
We are not currently supporting or performing testing with Boot Camp after Apple’s announcement to leave the Intel / x86 ecosystem with their new ARM based M1 systems.
Please don’t hesitate to let us know of other questions.
Thanks again for contacting Plugable support and best wishes!
The system ran it fine prior to using the dock. In fact, when directly connecting the monitor to the macbook pro the lag is gone. When connected to the dock the monitor lag is unbearable. The dock still serves the purpose of being the only single cord 100w power + all inputs.
It works with the HDMI i have connected to as it caps at 60hz, but the higher quality (more expensive) monitor with a 160hz refresh rate seems to have issues coming from the single cord set up on the right side of the laptop. Newer macbooks pros are known now to require that we charge on the right and display monitors on the left to avoid thermal throttling. This doesnt seem to be that, but am wondering if the cord is the issue.
Very interesting to hear that it’s now working in Boot Camp!
It’s possible that there was a system update from the macOS side that could have affected Boot Camp operation (like a UEFI update), or there could have been a Windows Update that corrected the behavior, it’s hard to say for sure.
