Didn’t Detect Another Display On Windows 10 – Solutions

Windows 10 has been a household name for a long time now. If you are a power user, you would want to connect a second monitor to your setup to get more done and increase your productivity. I also have a two-monitor setup, one being my laptop and another external display connected via the HDMI port on my Acer v nitro laptop.

I have run into issues before where windows 10 does not detect my second monitor. After reading lots of tutorials online, most of them guided me to click on the “Detect” button, and that should solve the issue. But, it just kept on giving me “Didn’t detect another display” message on windows 10. After lots of research and troubleshooting on my own, I might be able to solve some of the issues you guys might be facing.

There are different reasons behind windows 10 not detecting your second display. Let’s go through some of the major reasons.

Few reasons: Windows 10 didn’t detect another display

  • Check the cables: Assuming you have everything in place, I always like to go back and check everything from scratch. I have come into issues where a cable out of a new pack has been faulty. So if windows 10 is not detecting your second display, try another cable and see if that solves the issue.
  • Another port: If both of the monitors are connected using a VGA cable, try to see if there are other input ports on the monitor. But before you go out and buy a different cable, please make sure whatever system you are connecting the monitors to also supports that port.
  • System fault: I would also swap the system with another one only if I know that all of my settings are in place to make sure there is not something wrong with the system that I am trying to connect the second monitor to.
  • Dual monitor output not supported: It is essential that you are sure that you can connect two monitors that work as extended displays on Windows 10. If you have a full-blown system (a CPU), you should be good to go. But if you are trying to connect two monitors to a laptop, there might be limitations. You will have to do proper research on your won before you commit to buying new monitors for your laptop. The easiest way to find that out is to check if you have more than one port to plug in a monitor. (Even though you have a single port, there are ways you can connect more than one monitor to extend displays. But more on that in some other post)

Check the video source on the monitor

Some of the monitors have auto detect source settings on them, and they might be enabled by default. If your monitor has one, make sure that it is enabled and check if this solves the issue. If not, switch the monitor’s input source using the buttons on the monitor. But if you are not sure how to do this on the monitor you have, please find a guide respective to you monitor online.

Check your display settings

Let’s say you selected the right input source on the monitor and the other monitor is displaying correctly but the other monitor has a black screen, check your display settings.

Graphics-settings

  • Go to desktop, right-click and click on display settings
  • Scroll to the bottom of the windows and find “Multiple displays” settings
  • Check if the setting is not set to “Show only on 1” or “Show only on 2”

Cable Issues

If all the settings are in place but if you still cannot get windows 10 to detect another monitor, this might be some issues with the cable you are using to connect to the PC. Try changing the cable and see if this solves the issue

The second monitor is only duplicating the display and windows says “Didn’t detect another display”

If you have connected two monitors and all they are doing is duplicating the display, this is a driver issue. The scenario this applies to is, you have a system and you have two monitors connected to the system but you cannot extend the display and it only duplicates the display.

Update the display driver

9/10 times updating or installing the graphics display driver solves this issue. There are a few different ways you can download and install the graphics driver for your adapter. But the best way to solve this issue is to download and install the driver provided by your computer manufacturer.

So, how do you find the right driver for you adapter? Follow the below steps:

  • Go to Start and search for “CMD” and open it
  • Once you see the black window of CMD, type WMIC CSPRODUCT GET NAME and hit enter
    cmd-find-model-of-your-system
  • This will give you the model number of your system, go to google.com and type in the model number that you received in the previous CMD window and search for its the graphics driver
  • Once you download and install the graphics driver, it will solve this issue
