I have a Surface 5 and two monitors connected via the Surface Dock with usb-c and one 1 screen keeps flashing even after a firmware upgrade of the dock. ( this one: Surface_Dock_FwUpdate_1.53.139_Win10_17763_20.075.41193_0_AMD64.msi)
Attached is a screenshot of the surface app showing the details of the dock
thanks:)

switch the connection to the monitors A = Left and B =Right.
if A was the one flashing before and A is still the one flashing after switching connections it's the monitor.
if the problem moves to B then try switching the other end of the cable (don't move the one you already moved)
If the problem moves back to A the cable is bad otherwise the port on the dock is the problem.
Label everything before you start A or B and both ends of the cables A1, A2 and B1, B2. Also label the Dock ports A & b
 
OP
B

I might have confused that ... need more coffee ...
if the problem moves to B on the first cable switch and stays on B after the cable switch the cable is bad.
