I am using two setups, both have DDM 2.2 installed. 

one 3 monitor setup, one 2 monitor setup. 

- 3 monitor setup is as follows: 

   2 x dell (1x up3017+3014) and one eizo  

- 2 monitor setup is as follows: 

   2 x dell (2 x up3017). 

On both setups the DDM 2.2 wont work, it tells me to connect supported displays. So what's the next step to fix this? 

Cheers,
