Firmware Update needed to use DDM with DP 1.2

As a broadcast to all with the problem of Dell Display Monitor software (produced by "En TechTaiwan") working with DP 1.1 but not recognizing a dell monitor being attached when the monitor I/O is changed to DP 1.2:

I emailed "dell.support@entechtaiwan.com" with the following request:

Subject: Dell Display Manager Ver. 1.22.0.1554

 Hi,

 The above software is unable to detect my Dell U 3014 monitor when I have set the mini DP port to DP 1.2.

If I set the DP to DP 1.1 the DDM software can detect the monitor.

Please update ver 1554 to fix this problem.

I received the following response:

"I'm afraid this is not a software problem, and cannot be fixed thru a software update. It requires a monitor firmware update."

 I have a U 3014 (A04) with this problem but from the many complaints on this forum from dell customers with different monitors this necessary firmware upgrade is not unique to U 3014 monitors.

I am eagerly awaiting dell's firmware upgrade, but wondering how the firmware can be installed without sending the monitor back to the factory or a service depot. (Although eager I won't be holding my breath).

...and Chris, this should relieve you from having to make up excuses and wasting everyone's time and efforts with them - just tell them the truth.
