Guide to Solving the HDMI signal-free issue of Asus Laptops

It is not an uncommon problem for ASUS laptops to experience HDMI signalless. This article will introduce four solutions to help you quickly restore the display. Problems may result from connection failures, cable damage, monitor problems, graphics card driver failure, etc.

Method 1: Restart the monitor and computer

Many glitches can be solved with a simple restart.

Step 1: Turn off the monitor and computer.

Step 2: Unplug all cables connected to the monitor and reconnect after a few minutes.

Step 3: Turn on the monitor and computer to check whether the problem is solved.

Method 2: Check the connection

Incorrect or loose connections are the main reasons why HDMI has no signal.

• Check for bent or damaged ports and cables. If you have a spare HDMI cable, try replacing it.
• If the computer is equipped with a discrete graphics card, the HDMI port may be automatically disabled. Please connect the cable to the HDMI port of the graphics card.
• If you have multiple HDMI ports, try connecting to a different port.
• Avoid using the converter to connect the HDMI cable directly to the port, as there may be problems with the converter itself.

Method 3: Check the input source

Most monitors have multiple HDMI ports and need to select the correct port as the input source. While most Asus monitors will automatically detect, older models may detect errors.

Step 1: Press the Settings or Options button on the monitor to display the menu.

Step 2: Enter the input selection option, select HDMI 1, HDMI 2, DisplayPort and other options, and try one by one until the screen is displayed.

Method 4: Update the display and monitor drivers

Outdated or hardware-incompatible display drivers or monitor drivers can also cause HDMI to be signalless. Please update the driver in time. Since the driver cannot be updated with a faulty monitor, use another normal-functioning display device to operate.

Step 1: Press Win X to open the quick menu and select "Device Manager".

Step 2: Expand the "Show Adapter" category, right-click your graphics card driver, and select "Update Driver". Select "Automatically search for drivers" and follow the on-screen prompts.

Step 3: Expand the "Monitor" category and repeat the above steps for the monitor driver.

Hope the above method can help you solve the problem of HDMI signal-free ASUS notebooks. If the problem persists, it is recommended to contact Asus customer service for further support.
