7609WU, DP not working

I have a 7609WU projector that the DP stopped working.  Dell sent me a replacement and surprisingly the refurbished projector had the same issue.  Scans by the DP but doesn't see a signal.  I received another one refurbished one today and to my disbelief it also has the same issue!  No signal on the DP

I've tried swapping DP cables, multiple notebooks and I can only use VGA, HDMI, and component. If I plug the cable into a dell monitor it works as expected.

The original projector worked fine, for over a year then just stopped working on the DP.  What are the chances dell sent two projectors with the same issue?

I have the same problem, please see my posting 24/12-2015.

Did you change computer when the problem came?

Was the problem solved and how?

As I use a Matrox box with display port connection I have to solve the problem.

Connecting the Precision M4800 to the 7609WU projector with a HDMI/HDMI cable works fine.

"What are the chances dell sent two projectors with the same issue?

The same odds that I have.  I have two of these 7609s and neither of them work with a display port signal.  Dell's support is pretty non-existent for these.  The same computers using HDMI, display with no problems, but our issue is that we paid $4k for each of two graphics cards, and they only have DP outputs.  You'd think that Dell might join the 21st century and use 4 HDMI outputs instead, but I guess that's asking too much.
