I have this dock for several months and have had the same “awakening” problem that many others have had. Pluggable support gave me a patch to download but that only resolved the issue for a short while.
Now, in addition to the flickering, sometimes the display connected to the HDMI port does not receive any signal unless I unplug and replug the HDMI jack into the port. The other display, the one connected via the displayport, has no issues.
I’m truly surprised at the number of people who’ve had this problem and for how long it has existed.
Any help would be appreciated.
