I have a Dell PC with a separat graphics controller card from AMD.
The card has two ports, 1 DisplayPort and 1 DVI.
I have connected two identically Dell 22" LCD monitors, one with DP-to-DP cable and the other with DVI-to-DVI cable.
This was functioning perfectly!
Yesterday I purchased two new Dell 24" monitors model U2414H which has ports for DP, MiniDP + HDMI.
Monitor one was connected directly with the DP-to-DP cable and is working fine. HOWEVER the other monitor can NOT detect any signal??? I am aware that I can select input from the panel but nothing helps.
Its like the monitor does not accept to be connected with a DVI-to-DP cable.
Please notice, that there is nothing obviously wrong with the monitor, and if I switch this with monitor one (DP-to-DP) this works fine.
Can any one point me in the right direction?
