The monitor is not getting a signal and there is no error on the monitor. What do I do?
Try the following:
Check that the monitor’s video port works with another source.
Check that the cables between the source and the destination work with other equipment.
Check whether the video adapter works with another source and another destination. NOTE: Thunderbolt 3 to DisplayPort video adapters will require active adapters to convert from DisplayPort to DVI or HDMI.
