Find Out The Reasons First


1. Weak Power Supply

One possible reason for your ASUS monitor not detecting HDMI is a weak power supply. Insufficient power can cause display issues, including the absence of a signal.

Ensure that your monitor is connected to a stable power source and verify that the power cable is securely plugged in.

2. Damaged Cable

A damaged HDMI cable can also lead to a “display port no signal” error. Check for any visible signs of damage such as frayed wires or bent connectors.

If necessary, try using a different HDMI cable or test the current cable with another device to rule out cable-related issues.

3. Defected Displayport

A defected display port on your ASUS monitor can be another potential culprit. Inspect the display port for any physical damage or loose connections.

Consider trying alternative display ports or using adapters to determine if the issue lies with a specific port.

4. Backdated Drivers

Outdated or incompatible drivers can prevent your ASUS monitor from properly detecting HDMI signals.

Visit the ASUS website or use their software to check for driver updates specifically related to your monitor model. Updating the drivers can resolve compatibility issues and ensure optimal performance.

5. Hardware Problem

In some cases, a hardware problem within the monitor itself may be the cause of the HDMI detection issue.

If you have exhausted all other possibilities, it might be necessary to contact ASUS customer support or consult a professional technician to diagnose and address any potential hardware faults.
