Why am I not getting a signal from the 4K HDMI port?

I am using three monitors, there is no signal from the 4K port to my monitor. I have switched the cables around and confirmed it is not a problem with the cables or the monitor. My computer shows three monitors in the display settings, when I try the detect function, it is not seeing the third monitor, it thinks that my laptop screen is number 1, Is this a setting in my computer that I am missing?

Hi Michael,

Thank you so much for reaching out to us, I am sorry to hear that you are running into this issue, but I would be more than happy to assist!

I am concerned that we could be running into a compatibility issue. Would it be possible to obtain the model number of your system as well as the monitor you are attempting to connect to the 4K port?

Thank you for your time,
