Hi 

I am trying to connect a third HDMI source to my U3417W monitor, using the DP in and a HDMI to DP adaptor.

No matter what machine, or HDMI cable, or adaptor (I have a few), there is no signal.

My old HP monitor supported HDMI to DP (with a cable adaptor)

Just want to know if I'm wasting my time, or there's something wrong with the monitor

Thanks
