No signal to monitor when connected with DVI to DisplayPort.

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?

Have you got a second DVI-DP cable you can try? It sounds like a faulty cable.

Dear Akb

I am sorry the lack of feedback :-)

It turned out, that for some strange reason even then monitor could not detect any input when provided by either DVI-DP or DVI-mDP.

The solution was to use a DVI-HDMI cable.
I can't figure out why this was so.

I had PLENTY of DVI cables to try, so I was sure, that the problem was not a faulty cable.

Me closing the case was not meant in desrespect to you nor EE.
I just figured it out my self, and did not thought an input from me was preciated.

Have a nice day :-)
