My Asus zenbook Micro HDMI port does not seem to connect to an external monitor via micro HDMI cable. I have tried multiple cables and multiple monitors, however, it does not seem to detect anything. I have updated the BIOS and drivers.
A solution which made it work for a split minute was:
Unplug everything
Reconnect the monitor to the power
Reconnect HDMI cable to the laptop
Power up the laptop
This solution worked for maybe 30 seconds before the monitor went blank again detecting "no signal". The monitor detects a connection but does not receive a signal. The laptop does not detect an external monitor.
The monitor connects with no hassles via the USB-C port.
