Maybe there is some issue going on with your computer’s graphics card settings. Or, it is just some hardware issue of the monitor itself. Whatever it is, we will be providing you with some simple fixes that can help you get out of this situation easily.

Hence, if you are looking for methods to fix the problem where the monitor is detected but not displaying, stay tuned till the end as we will be going in-depth to find the right fix.

Monitor Detected But Not Displaying – How to Resolve This Issue

Is This the First Use?

Before directly jumping to any conclusions or start finding the fixes, we must find out why this problem is occurring in the first place? Have you experienced similar issues with the same monitor or other monitors ever before? Or is it just happening for the first time with the new monitor?

If that happens frequently with your computer monitors, then it may be due to some software issue or may be related to your graphics card. However, if other monitors are working fine, and the new one isn’t, then it is pretty clear that the monitor has some sort of issue.

Restart Your Computer

No matter what sort of problem occurs with your PC, a casual reboot can significantly fix most of the basic bugs. Generally, PCs with older hardware do sometimes struggle a bit to load and configure new hardware like secondary monitors.

With a fresh restart of the PC, if there is some problem going on with the drivers, it will get fixed. Just make sure the computer is connected to an active internet connection at the time of rebooting.

Test with an Alternative Configuration

If restarting the PC doesn’t help you, there’s another thing you can try out. Since you have got two monitors and one of them is only working, try swapping the connection ports. If the primary monitor works with other ports as well, the 2nd monitor might be faulty.

Otherwise, there must be some issue with the port only. In case your primary monitor works fine with all ports, there are high chances that the 2nd monitor’s wire is faulty. Try testing out the monitor with different configurations, you can use HDMI connections, DisplayPort connection and see what works best.

Are the Graphics/Monitor Drivers Updated?

If you are using a graphics card, either from Nvidia or AMD, keeping the drivers updated is a necessary task. Sometimes, due to the older drivers, several graphics cards may show you problems like this. Hence, make sure all the drivers on your computer are updated properly, and then try reconnecting the monitor to the PC.

Checked for Any Viruses

The chances of facing such kind of problems because of a computer virus is very little. However, if you have checked for all the other possibilities, this is the last one to be worried about. Try running a full system scan with the help of any anti-malware or antivirus software on your PC. Moreover, if there is any pending Windows update, try installing that as well.
