Dell P2314H Monitor Cannot Connect to Macbook Pro I've got a late 2013 model 13 inch Macbook Pro with Retina Display, and a new Dell P2314H monitor. 
I keep getting a message on the monitor saying its going to sleep. I've tried the following:


Display port to HDMI cable where the HDMI is connected to the MBP, and the DP is connected to the monitor.
VGA cable to the monitor and an HDMI cable to the MBP.
Points 1 and 2 with Thunderbolt adapters connected. 


I still keep getting the same message.

I've been using passive adapters for this, im not sure changing them to active adapters will fix this. 

Anyone have any ideas?
Got myself an active adapter between my DVI port and hdmi. Connected one end of the DVI cable to the monitor and the other end of it to the active adapter. Data going in through the mac to the monitor was converted and it all worked like a charm.
