After trying to run testdisplay -a on CNL using multiple displays, I found that
when test start on eDP and finish testdisplay -a hangs the platform and the
other monitors never shows any activity.

1.Connect eDP, HDMI and DP
2.Run testdisplay -a 
3.Check that no all resolutions are supporten on eDP, and after finish with eDP 
hdmi and dp never start the excecution of testdisplay
