Dell does not sell a specific TB (Thunderbolt) to DP (DisplayPort) or mDP (mini Display Port) cable. Did you test to see if the P2715Q mDP to DP cable fits in the TB/mDP port? If it does, connect in this way =
Laptop TB/mDP out --> P2715Q mDP to DP cable --> P2715QDP in
I am a little confused and I'm seeking someone able to really help.
My problem is quite the same but I want to explain a little more in detail what I want to do and I'm not able to.
I have the P2715Q, awesome.
I have some Mac Mini brought recently 2016 & 2017
I would like to use my screen with 3840*2160 @60Hz.
Today I can only achieve 3840*2160 @30Hz with the Dell provided miniDP to DP cable.
From what I read some people succeed doing this by connecting a thunderbolt cable to the thunderbolt port of the Mac mini. They arrive to 3840*2160 @60Hz.
What it is not clear to me is if I can plug the thunderbolt cable directly into the miniDP port of the monitor or do I have to have an adapter DP (male) to miniDP (female) to do so?
I have tried with my Apple Thunderbolt cable (that works fine) connecting miniDP on the Mac mini to miniDP on the monitor and I have no signal at all.
I do not care to handle data on thunderbolt cable, just the signal, but it has to be 60Hz.
I'm considering changing my entire company monitors to this awesome screen model I really like but I need to be sure I can achieve the frequency.
Thanks in advance for your wisdom on this.
I think the monitor might have some physical issue on the miniDP at the back?
Minis miniDP are Thunderbolt 2 (so 1.2 miniDP)
In the user manual I read it is a IN port, so it should work right?
Thanks in advance for your answer.
