Windows 10: Using old windows 10 laptops as external monitors and my new one as well.

So My main laptop I always have with me is a windows 11 pro latitude 5300 2in1 and I'm looking for it to become more versatile. I wanna use it on trips as a external monitor for my switch and i have dongles and adaptors so it doesn't matter if the hardware allows it as i can circumnavigate this. basically I'm either asking if there is already a built in way to make my laptop a display as long as they have windows 11, or asking for this to become a feature eventually due to the versatility and usefulness of said suggestion. Sincerely, A nerdy gamer that loves windows.

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.

 

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

Hi,

Thank you for posting your concern on Microsoft Answer Community.

We need few information.

• What is the make and model number of the External monitor?
  
• What is the connection type, HDMI cable/VGA cable?
  

We would suggest you to follow the methods mentioned below and let us know if that helps.

Method 1:

1. Make sure the computer has power. If the computer has turned off, it will not be transmitting a signal and cause the "no input signal" message.
   
2. Verify that the monitor is properly connected in the back of the
   monitor, as well as to the back of the computer.
   
3. Some newer monitors are capable of connecting to a computer using a VGA or DVI connector. For these types of monitors, the correct input selection needs to be used.
   
4. Access the settings on the monitor using the buttons on the front or bottom edge of the monitor.
   
5. Look for options to select the type of connector being used, either VGA or DVI, and select the correct input being used for your monitor to connect to your computer.
   

Method 2:

1. Press and hold the Windows + X key on the keyboard. Select
   Device manager.
   
2. In Device manager, expand Monitor.
   
3. Check the status of the driver and if required try to update it.
   
4. Right click on the device listed and select
   Update drivers. You will get a new window, please select "Search Automatically Updated Drivers Software".
   
5. In Device manager, expand Display.
   
6. Right click on the device listed and select
   Uninstall device.
   
7. You will receive a prompt, make sure you check the box for
   Delete the driver software. Then perform method 3.
   

Method 3: Download and Install the recent video driver.

Seems that there is an updated video driver setup available in Dell
website.
Please select the category as Video.

Hope it helps.

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!
