I am trying to run 2 external monitors with my Early 2015 MacBook Air. I am using the Mini Display Port and a USB to VGA by j5Create. Everything was fine but today the monitor using the mini display port keeps going black even though the power is on. Sometimes when it happens I can go to the monitors in system preferences and it will show the 3 monitors and sometimes it will not. Regardless, it doesn't help me get the monitor to come back. When I unplug and replug it the monitor shows a picture and then goes right back off. I rebooted my computer and it worked for a little while and then it just went blank again.
Does anyone know what is going on or how to fix it?
