Method 1: Unplug and plug the DisplayPort cable

Asus monitor no signal issues are more likely to be caused by bad connections. You can try to unplug the DisplayPort cable and plug it back in.

Method 1 and Method 2 should work in most cases. But if they don’t work for you, move on to try other methods.


Method 3: Connect the monitor with another type of cable

A broken DisplayPort cable can cause Asus monitor no signal issues. To resolve the problem, you can try to connect the monitor with another type of cable like HDMI cable and DVI cable. As for what type of cable you should use, it depends on what video ports your video card has.

If the problem is resolved with another type of cable, you can try Method 4, Method 5 and Method 6 which can allow you to continue to use the DisplayPort.

If the problem still persists, try Method 7.


Method 4: Check Nvidia control panel settings (for multiple monitor users)

This method applies to Nvidia graphics card users. If you’re using another brand graphics card, skip this method. Not sure what graphics card you have?

If you’re experiencing the issue with your second monitor or third monitor, you can try to check the Nvidia control panel settings. If the monitor is not selected in the Nvidia control panel, the monitor DisplayPort no signal issue can happen.

Here’s how to check if the monitor is selected in the Nvidia control panel.

1) Open Nvidia control panel.

2) Expand Display and select Set up multiple displays. In the Select the displays you want to use section, check if the checkbox next to the Asus monitor is checked. If it’s not checked, click to check it. After that, check to see if the problem resolves.

Method 5: Try a new DisplayPort cable

If none of the above methods works for you, you can try a new DisplayPort cable. If the new cable resolves the problem, you’ll need to replace the old cable with the new one.


Method 6: 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 broken 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.
