Thanks for the reply. I contacted the manufacturer directly (of that cable) and they told me (after checking with the factory), that the pin20 is connected in their cable. As they wrote (which is correct), pin20 is sometimes needed and sometimes not needed (my point is that there are other manufacturers, that make DP cable with pin20 connected). So it is not a fault in the cable, the problem is that with cables that have pin20 connected, problems might occur. In my case I have problems with my laptop for 3 months. Maybe it's also in the u2311h, maybe it puts too much 'power' through the cable and damages the laptop. Maybe it only happens with my config (Latitude E6400 and u2311h). But since I read other users having same problems (altough they didn't seem to deal with permanent damage to their stuff), I think it would be nice from DELL to inform it's customers not to use such cables, because they can cause damage. Or just provide a 'ok' displayport cable with the monitors, since Latitude laptops don't have DVI.
Now I'll try some cables that don't have the pin 20 connected and I will let you know, if it works (I guess it would).

filster,
I cannot speak to the 3rd party DP (DisplayPort) cable. This is the one we tested.
