Does not detect second monitor

HP Recommended
HP V28 4K Monitor
Microsoft Windows 10 (64-bit)

I purchased two new HP V28K Monitors. I have them both connected to display ports on my docking station but only one monitor will work at a time. Windows will say it can't detect the second monitor even though it will display it as monitor 2. I replaced one of the monitors with my old Acer monitor and they will both work, the new one and the old one with extended display but when I change my old monitor for the new one again, I get the same problem where it won't detect the new monitor. It will only work if I turn the other monitor off. I hope someone can help.

What is the resolution of your old monitor ? Looks like two 4K monitors are too much for your machine to display. What is your docking station ? Does it support 2 x 4K monitors ?

 

Regards.

The old monitor is 1920 x 1080. The laptop itself is an Elitebook with intel core i7 processor. It’s a work computer and relatively new so I don’t understand why it can’t support two 4K screens. The docking station is a HP docking station. I don’t know what model it is but it has two display ports... no HDMI. My laptop has a HDMI port but I can’t access it when it’s on the docking station.

I don't know what is your Elitebook with intel core i7 processor. The latest one could be G10 Intel processor with Intel® Iris® Plus Graphics 640

As you can see, it supports one 4K monitor, not 2. The dock may help a bit. What is your dock on the following list ?

Hello,

It’s the ultraslim docking station.

So if my computer does not support two 4K screens then I purchased one screen too many? Is there any way of getting around it?
