I had this tought aswell, "Hey nice DP output, let me convert that real quick" - but no.
Just as Daniel said, only DP to DP will works flawlessly with all monitor.
I contacted my local MA dealer, and asked if they would recommend any adapter for DP to HDMI for my issue, but he told me no.
He instead told me to get at laptop in session and use my laptops hdmi out to show 3D.
Wich is great, I can use the wall mounted screen by the test bench, and now i will get used to have a laptop in session, so i will always have an updated version of my showfile if somebody spills coffe in the Compact XT
