Method 1: Unplug and replug the HDMI cable

If the monitor is not fully connected to the computer, the HDMI no signal issue can cause. To fix the problem, you can try to unplug the HDMI cable and plug it back in.

After plugging the HDMI cable again, check if the cable is inserted firmly into the ports. Ensure it’s well connected at the ASUS monitor end as well as the computer end. You can pull it out and see if it’s hard to pull out. If it’s hard to pull out, it means the cable is inserted firmly.

Method 2: Unplug and replug the monitor power cable

To fix your ASUS monitor hdmi no signal issue, you can try to unplug and replug the monitor power cable. Many Windows users have confirmed they had resolved their problems with this method.

First, unplug the power cable for a couple of minutes, then plug the power cable again.

After that, check to see if the problem persists. If it still persists, move on and try other methods.

Method 3: Perform a factory reset on the monitor

To fix the problem, you can try to perform a factory reset on the monitor.

First, press the on-screen menu button on the monitor to bring up the On-screen menu. Then use the buttons on the monitor to select the Factory Reset option. If you have no idea how to select the Factor Reset option, you can search the monitor user-guide online.

Method 4: Try a new HDMI cable

If the HDMI cable is damaged, the monitor can’t get the input source successfully. In this case, the no signal issue can occur.

You can try a new HDMI cable and see if the problem persists. If the problem is resolved, just use the new HDMI cable. Or try Method 5.

Method 5: Test the ASUS monitor on another computer

The last method you can try is to test the monitor on another computer. If possible, connect your ASUS monitor to another computer and see how it works. If it doesn’t work on another computer either, the problem is probably caused by a damaged monitor.

You may need to replace it with a new monitor. If your monitor is still under manufacturer’s warranty, contact their support for further assistance.

  1. This all started when I decided to upgrade my cpu and motherboard.. originally I had a Ryzen 7 2700x and an Asus prime x370 pro also a one month old Samsung odyssey g7 32” monitor. So I decided to upgrade to a Ryzen 5 5600x and tried 3 different motherboards (Asus b450f gaming, Asus b550 f Wi-Fi, and msi x570 tomahawk) the reason for that is because I’m a little rusty while building pc’s and no one at the store told me that the b450 had to be flashed. So my problem now is I keep getting a “display port-no signal” and can’t even see bios. I tried hdmi and same thing, oh and I used multiple different cables. At this point I gave up for the night and sweating bricks thinking it’s my gpu.. so I took it to a local place to diagnose my Pc and it posted for them and were able to see the bios/uefi. So now I was starting to think it’s my month old monitor. So I exchanged it for an Asus rog strix xg27aq at microcenter and that came with a new set of cables (hdmi and DisplayPort) plugged it into my rig and it’s doing the same damn thing. So this time I took my rig to microcenter and they plugged it in and I saw with my own eyes that it posted there too.. so now while I was there I bought a new power cable for my Pc and a new surge protector and got back and switched off the main power outside and turned it back on and still “display port-no signal”. I also tried a different wall outlet as well and I’m so frustrated. One thing I forgot to mention is that when I go to my monitor’s OSD the ‘system setup’ is greyed out and I remember that being greyed (if I remember correctly) on my Samsung g7.. do you guys have any ideas so I don’t have to contact a psychiatrist lol? Btw all the fans and rgb inside my rig are on. Is this super shitty bad luck? Because I’m clueless with how to proceed at this point.. sorry for the long rant..
