Disabled 3rd Monitor Windows 10

I installed a 3rd monitor connected to the 3rd port in my video card in my HP desktop. Win 10 sees the 3rd monitor but will not allow me to change the disabled. If I disconnect one of the first 2 monitors, the new 3rd monitor becomes
active. So, all of the connections, ports and monitors are compatible, good and working. Somewhere Win 10 is restricting me to 2 monitors at a time and I need to change that but haven’t been able to determine how. Video card drivers have been updated and
are current.

 

connect 3rd monitor

My HP pavillion will not detect a 3rd monitor I connected to the USB-C port. Is there a way to detect / connect the 3rd monitor ?

 

2nd and 3rd monitors freezing

I'm on the latest Windows 10 version.

At random times (normally after leaving the computer in sleep mode) my 2nd and 3rd monitors freeze up, resulting in static images of what's there. I can still (somewhat) do things on them, but they mostly remain frozen. For example, I can make a fullscreen
application windowed (ctrl+shift+f) and vise versa. I can also move things from either one of the monitors to the 1st monitor, but I can't do this the other way around. When I move them, they still appear frozen on the 2nd or 3rd monitor whilst being dragged
to the 1st, and they stay there when being dragged from the 1st.

Turning off the 1st monitor (pretty much unplugging it due to the monitor) allows the others to function freely, but when I turn it back on, the problem restarts. This happens when unplugging the monitors as well.
