Windows 10: External monitor "no input"; worked with old laptop and intermittently with new laptop

For nearly one year I've been using an external monitor to extend my display. Over the year my set up has stopped working three times and I get the message on the external monitor "no input" when I plug in the cable to my laptop.


I have worked with Dell's IT support on this issue each time to resolve the issue but I would like to figure out how to stop this from happening and/or resolve it on my own when it does happen. Dell IT support eventually fixed the problem after trying many solutions and it was too convoluted for me to follow, so I cannot recreate what was successfully done to actually solve the issue. And I don't understand why it is reoccurring. I had zero problems with this external monitor with my old laptop.


Here's a summary:

- laptop always makes the chime sound when the cable to the external monitor is connected and disconnected; "no input" flashes on the screen of the external monitor

- sometimes I can get the external monitor to connect again if I hibernate my laptop and then wake it up; sometimes I need to shut my laptop down completely and restart to get the monitor to connect again; putting the laptop to sleep and then waking it up never resolves the problem

- I turned sleep off entirely because usually if my laptop went to sleep then the external monitor would no longer connect upon waking
- I turned off the laptop screen time out (i.e. laptop goes to screen saver or just turns off) because the external monitor would no longer connect afterwards
- In Settings, Display, I have tried the "Detect" button to try to connect to my external display; it doesn't work and I don't think it has ever worked
- I updated BIOS a few times and it did not help; I eventually had to roll back to a BIOS that was four versions older in order for the monitor to connect again
- I updated video card drivers (and a few others that I don't remember because it was months ago), and this did not seem to help
- My setup has been working for the last three or four months until yesterday and now I can't get the monitor to connect no matter what; the only update/change I could see that happened was an update of the "Definition Update for Windows Defender Antivirus", but perhaps there were other updates that happened that I don't know how to check for
- I've had three blue screen failures in the two months, and I think one or two others in the last year; stop code: unexpected store exception


I hope I've given enough detail here. Thanks in advance for any suggestions!

Laptop suddenly stopped recognizing the external monitor

Hi,

Thank you for posting your query in Microsoft Community.

To assist you better, I would like to ask if the laptop is unable to recognize only the external monitor or other external devices also.

I suggest you to run the Hardware and Devices troubleshooter by following the steps below:

• Click on the Start button, and type “Troubleshooting” on the search bar.
• Click on “Hardware and Devices”.
• A pop-up will appear, click on the “Next” button and your hardware troubleshooting will start.
  

Hope the information is helpful. Keep us posted on the status for further assistance.

 

Laptop External Monitor Problem


Thank you once again, I will explain:

• Today 10th November 2016 - After monitor eventually successfully connects to my HP laptop, in my absence when the laptop/monitor powers off, I get NO re-connection problems during the day
• Tomorrow 11th November 2016 - After laptop and monitor has been restarted following, shut-down, power offs(laptop + monitor) I will be stuck once again with exactly the same problem

In my display settings each morning, my HP laptop shows it is connected to my external monitor, however there is no display on the external monitor for a vast amount of time, just randomly suddenly appears.?

 

Laptop will only work with external monitor after windows 10 upgrade, HP Pavillion laptop

Hi,

I took the steps and it did not work. When I did the reboot, it went to the desktop on the laptop and then while still finishing the reboot, screen again went dark. I had to plug in the external monitor again. The laptop monitor works fine, the software
keeps making it that I can only use an external monitor. I still need help. Thanks.
