Get To The Bottom Of It First.

You can cure your problem quickly if you know what’s causing it. When your Asus HDMI monitor does not respond, you need to know the cause of the problem so that you can fix it. In addition, you can take steps to prevent the problem from occurring again in the future.

Power Supply Issues

Keep in mind that proper operation of your electronic equipment necessitates a steady stream of power. An unreliable power source might do serious damage to your computer. HDMI signal loss can also be caused by using a shoddy adapter or multiplug with a shoddy cable.

Damage to a Wiring

A damaged HDMI cable is the most common cause of an HDMI no signal message. In addition to your power cable and DVI cable, you may also lose your DisplayPort or HDMI cable. The cord’s power supply capacity can be harmed if the wrong thread is used in the wrong port.

Display Port That Has Been Infected

It’s possible that the ports on the back or underneath your Asus monitor will be harmed as well. The HDMI port, as well as other display ports, can be damaged by improper insertion, overheating, or overload. This can be caused by a lack of knowledge about which port is compatible with which cable.

Incorrect Drivers

The display may stop operating if the relevant drivers, such as those for your chipset or graphics card, are out of date. Due to their inability to match and recognize the new display, out-of-date graphic drivers have rendered themselves useless.

A Hardware Issue Has Occurred.

Incorrect positioning, bad configuration, and loose connections can all harm your PC’s hardware. Monitors can malfunction from the inside out. Hardware like a video card, CMOS, or motherboard can also fail to function properly if they are faulty, loose, cracked, or burned.

Asus Monitor HDMI No Signal Solutions

No technology, including your Asus monitor, is error-free. Make sure you don’t lose any control if your HDMI-based Asus monitor is not showing any signal. You can resolve this problem by following a few simple but effective steps.

First-Line Options

Examine the source of your power.

To begin, you must ensure that you have a steady source of electricity. If your main or wall outlet, socket, and receptacle are working properly, you can proceed with your project. Use an adaptor to power both your display and power supply at the same time, if you have both.

Initiate A New Connection

The first step is to restart or reconnect all of your devices and all of their connections. Remove the power cords from your television, monitor, and computer. Remove all HDMI cables from the computer, monitor, and adapter. Reconnect them all and get to work after some time.

The Ports of Call

You need to check the HDMI ports first because this is an HDMI-related issue. Inspect your monitor, computer, and HDMI adaptor for dirty or broken HDMI inputs. Disconnect and re-connect the HDMI cable from each of the ports on your TV.


Damaged cables need to be replaced.

It’s best to toss away damaged HDMI cables and monitor power cables and get new ones as soon as you see any damage. Using outdated HDMI cables or patching them with scotch tape is also a bad idea.

Is it your television or your cable provider?

Replace the HDMI cable that’s connected to your Asus display if the first one doesn’t work. You have a problem with your cable if it does not work. Use a different computer to see if it works. You’ll be able to determine if the problem is with the hardware and go on.

Optional Remedies

Maintain Up-to-Date Driver Software

Your graphics card or driver must be updated to the most recent version. Update the chipset drivers in display settings as well. Use a third-party setup if you don’t know how to or are afraid to update the drivers, and it will do so automatically.

Ensure you have the proper resolution and refresh rate set.

Check to see whether your Asus monitor’s resolution is lower than your graphics card’s before turning it on. The graphics card needs to be able to support the monitor’s resolution, so make the appropriate adjustments. A refresh rate check is also a good idea.

Monitors need to be reset.

The final resort before resorting to hardware is to perform a factory reset on your Asus display. The option to reset depends on the type of display. Hopefully, the HDMI no signal issue can be fixed by a factory reset.

The Final Answers

Check Your Computer’s Hardware.

Even if you’ve tried all of the above, there’s a good chance the issue stems from your computer. Open the PC’s case and make sure that all of its components are in good working order and have not been damaged or replaced.

It’s a good idea to double-check your video card’s CMOS, graphics card, RAM stick, and motherboard. If you discover a problem, don’t hesitate to visit a nearby service center and have the broken part repaired.
