Problem: When my computer auto locks (may occur on manual locking), all my monitors compress to one (the pluggable). I have four monitors. After logging back on, the Plugable monitor (#4) is the only monitor active. The other three are listed as “deactivated”. I cannot manually activate the monitors. I must reboot.
Back ground: I have a Dell Latitude E7240 in a docking station. On the dock I have two HDMI and one VGA port. Each of these are connected to a monitor. I just purchased a UGA-3000 and have attached to my computer. At attachment, the drivers were downloaded and installed. I was then able to configure the monitor as desired.
