I have a B30 connect to a pair of identical 3840x1600 displays, the dock is running the current firmware
I am using the two HDMI inputs - one with a PC, and the other with a Mac
For the first few months this setup works perfectly but is becoming increasingly unreliable - the UDID codes for the displays will stop being passed through to the computers which will then revert to 640x480 display modes. Sometime this happens with both displays, sometimes with only one.
If I power cycle displays, or the dock I can sometimes restore a working configuration.
It has now got to the point where I am thankful if I get one working display and am able to use the system at all.
How to troubleshoot this, or arrange for a replacement unit?
