When using 2 Display Port Cables I get a No Signal Error on my xl2420z. Dual Monitor ISSUE!

KOREY MARKOVIC Dec 26, 2017 05:08PM CST

I'm having a bizarre issue. When I plug in my xl2420z using a displayport cable on its own I'm able to use it without any issue or hitch. If I plug in my xl2420t with another displayport cable it will cause my xl2420z to go black and display a no signal message.

Though If I use my DVI-D on my xl2420z and DP on my xl2420t there is no issue.

Any Ideas? I have tried completely wiping and reinstalling my video card drivers with no avail.

That is really strange! These are both being connected to the GPU (not the mobo), correct? What GPU do you have?

EVGA NVIDIA GTX 1080 FTW, and Yup both are plugged directly into the GPU

Hello Korey,

Have you tried hooking them up one at a time? Do you get a different result?

Do they show up in windows or your NVIDIA control panel?
