Q: Dell U2417H NOT working on my Mac Pro Tower 5,1

I can't get a brand new Dell U2417H working on my Mac Pro Tower 5,1 (ATI Radeon 5770 HD 1024MB running El Captain) with the Mini DP to DP cable the monitor came with. I just get the "No DP signal coming from your device" message on screen... Any Ideas?? I haven't tried any other cables yet Mini DP to Mini DP or Mini DP to HDMI - I'm reluctant to spend money on something that may not work??

Mac Pro, OS X El Capitan (10.11.6), null

why haven't you tried another cable? or connect directly to the DVI on the back of the 5770 and take the mini DP out of the equation for a moment?
