Fix: Asus Monitor Showing No Signal With HDMI

It can be frustrating when you connect your Asus monitor to your computer or device via HDMI and get no signal.

A black or blank screen usually indicates no connection between the monitor and the PC.

Before you panic, there are several troubleshooting steps you can take to fix the Asus HDMI no signal issue.

This article will cover the common causes and solutions to try.

Quick Answer:

Ensure the HDMI cable is securely connected at both ends and select the correct HDMI input source on the Asus monitor. If the issue persists, try a different HDMI cable or port.

Common Causes of Asus Monitor No Signal HDMI

Here are some of the most common reasons why your Asus monitor might show no signal when connected via HDMI:

1. Faulty or Loose HDMI Cable

The most apparent cause is a faulty or loose HDMI cable.

Check that both ends of the HDMI cable are securely plugged into the monitor and PC ports.

Try connecting the cable to another device, like a games console, to see if the cable works. If there is still no signal, replace the HDMI cable.

2. Incorrect Input Source Selected

Your Asus monitor menu may have the wrong input source selected.

Access the monitor settings menu and ensure HDMI is enabled and selected as the active input source.

3. Outdated Graphics Drivers

Outdated, corrupt or missing graphics drivers can cause connection issues between the monitor and the PC.

Update to the latest graphics drivers from AMD or Nvidia.

4. Incompatible HDMI Version

An older HDMI 1.4 cable with HDMI 2.0 ports could result in no signal.

Check your HDMI cable is Version 2.0 or above for 4K displays.

5. DisplayPort Mode Enabled

Some Asus gaming monitors have a DisplayPort mode, overriding other inputs like HDMI.

Go into the monitor menu and disable DisplayPort or MST mode.

6. Bent HDMI Pins

Check the HDMI port for damaged or bent pins that could cause a bad connection.

7. HDMI EDID Communication Issue

The monitor and PC need to communicate EDID data to establish a relationship.

Restart both devices and check HDMI cables are fully secured.

How to Fix Asus Monitor No Signal HDMI

If you’ve checked all cables and connections, here are some other fixes to try:

1. Hard Reset the Monitor

Turn off the Asus monitor and unplug the power cord for 2 minutes. This resets the monitor and clears any erroneous EDID data.

2. Use a Different HDMI Port

If available, try using another HDMI port on the monitor and graphics card.

3. Reset Graphics Card

Uninstall the graphics drivers, shut down the PC, remove the graphics card and reseat it properly.

Restart your PC and reinstall the latest graphics drivers.

4. Factory Reset the Monitor

Access the monitor menu settings and select Factory Reset to restore default settings which may fix HDMI issues.

5. Update BIOS, Chipset and Firmware

Outdated motherboard BIOS and firmware versions can cause monitor connectivity problems.

Check the Asus website for updates.

6. Change HDMI EDID Settings

In Windows Display Settings, you may need to adjust HDMI EDID settings to fix communication issues.

If you still have no signal after trying these troubleshooting steps, the last resort may be to replace the HDMI cable and use a new one.

Please contact Asus support if the display is still not detected.
