Windows 10: My laptop won't accept some external monitors

Dear all,


I have the following tricky problem. I have an Asus laptop with windows 10. Recently I bought a new 27" Dell Monitor and plugged it with HDMI cable to my laptop. My new Dell was not recognized and I got no signal on screen. I tried with a widescreen Asus monitor (I guess it is 24"), same outcome. I tried display settings --> Detect. It did not detect the monitor in both cases. I checked the display adapter, it is up to date. I tried to install the Dell monitor's adapter, the software did not detect the Dell monitor and did not install anything.


Interestingly, with an old 20" Asus monitor the laptop is working perfectly well. I used, two different HDMI cables, same outcome. The Dell and large Asus Monitors work perfectly well on other computers. So, I think it is a software issue.



Thanks a lot for your help

:)

 

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.?

 

After Windows 10 update, signin screen won`t accept my pssword.

Sign-in screen won`t take my password after Windows 10 update on a new HP laptop. I had setup a pin login but now asks for Microsoft password which I wrote down and have used before but will not accept now.
