Windows 10: Adding a monitor to my laptop causes display loss

I tried to add a monitor (Benq GL2460) to my Lenovo Yoga 310 (Win10) but when I connect it (HDMI cable), I lose the fill screen display and can't access anything (i.e when I try to open an application or service it won't display on my laptop screen or added monitor). When I unplug the HDMI cable the laptop returns to normal. Any ideas?

Laptop display question

Confusing statement! You want to change the display on your laptop that died?

Is that correct?

How do you know its the display that's bad?

Just google "how to change display on a acer 5745"

Should get you to step by step instructions. But first make sure its the display that's bad

 

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.

Hi Kathy,

This issue with monitor display can be caused by screen resolution problems.

As an initial troubleshooting step, try changing the screen resolution by following the steps below:

• Right-click on the desktop screen.
• Select Display settings.
• Click Display.
• Under Resolution, click on the drop-down menu and change the screen resolution.
  
  Note: You can select the most recommended resolution (1920 x 1080) if applicable and see if the issue will persist.

Let us know if you have any other concerns.
