Weak Power Supply 

Remember that your electronic devices need a smooth power flow to work correctly. If you have an interrupted power supply, it can harm your PC. A poorly constructed cheap adapter or multiplug with low-quality cable is also responsible for HDMI no signal.

Damaged Cable

A broken HDMI cable is a primary reason you get HDMI no signal notification. Even your other cords like power cable, DVI cable, and DisplayPort cable can be damaged. Putting the wrong thread into the wrong port can damage the power supply ability of the cord. 

Defected Display Port 

The ports behind or under your Asus monitor can be damaged too. Force input, wrong insertion, overheating, or overpowering can harm the display port, including the HDMI port. Not understanding which port goes with which cable can lead to this problem.

Backdated Drivers 

If your deceive drivers like chipset drivers or graphic drivers get out of date, you may face the monitor not working issue. Backdated graphic drivers can not match and detect with the new monitor, so they became unable to send the signals properly.

Hardware Problem 

Loose connection, poor setup, and wrong placement can cause damage to your PC’s hardware. Your monitor can be faulty or broken from the inside. Also, hardware like the video card, CMOS, or motherboard can be flawed, loose, broken, or burnt to work correctly.

Restart The Connections

Restarting or reconnecting your devices and all the links is an initial thing. Disconnect your tv or monitor and PC from the power source. Unplug all the HDMI cables from the PC, monitor, and adaptor. After some time, reconnect them all and start working.   

Check The Ports
