Windows 10: External Monitor Couldn't Display From My Laptop

Hi, I've a problem.I've connected my displayport from my laptop through thunderbolt adaptor but my external monitor shows that there isn't any signal.My laptop detected the monitor but the monitor doesn'tCan someone help to fix my problem?Thanks

:)

 

No display on laptop's external monitor-Monitor recognized but blank

After the recent Windows 10 update, my wife's laptop no longer displays on the external monitor. All was well before the update.

I am comfortable that Windows sees the monitor because clicking on Display Settings shows two displays. If I unplug the HDMI cable, only one display is shown.

I have confirmed that the monitor works by trying it with another laptop. I have also changed the HDMI cable between the laptop and the external monitor.

Device manager reports that I have the latest display driver installed.

I would appreciate any and all suggestions.

 

External monitor display settings

Hi,



Thank you for posting in Microsoft Community.



I understand that you are facing issues with the display scaling on your external displays. We will certainly look into this for you.

As you are using Vizio TV, you may have to try using custom resolution settings if the in-built settings do not provide the required settings.

For better clarity, please let us know:

• What is the version of Windows 10 that is currently installed on your computer? You can click on Search and type
  winver.
• Are you aware of any recent changes to the system, such as updates, after which you are facing this issue?
• What is the make and model of your computer?

Meanwhile, I would suggest you to check the steps mentioned in the Workaround section in

Windows scaling issues for high-DPI devices

I would also suggest you to check the Display drivers. Please refer

Let us know how it goes.

connection problems External Monitor for laptop

If you're trying to use a wired external monitor is it connected to the laptop's HDMI output connector or the mini DisplayPort connector?

If you're using a wired external monitor and don't see any output, right-click on an empty spot on the Desktop and select Screen Resolution -> Detect

In addition, you may need to press the F7 key and select the mode in which the display will function. There are 4 modes:

• Disconnect (or Computer only): display only on the laptop's screen
• Duplicate: the same display on the laptop's screen and the external monitor
• Extend: extends the output so that you can drag things from one screen to the other
• Projector only (or Second Screen Only): displays only on the external monitor

Or are you trying to use wireless (Wi-Di or Miracast)?
