The computer is currently connected to the LG 5k display. When I try to connect an older 24" dell monitor, using a display port to usb-c cable, the dell monitor will not power on. However, if I unplug the LG display, the dell monitor will power on. If I restart the computer with both monitors plugged in, only the LG monitor powers on. If I connect the dell monitor first, then plug in the LG monitor, I can get both monitors to power on.
