Windows 10: How Do I Get My Windows 11 Asus Laptop to Detect External LG Display?

I recently purchased an LG monitor for an ASUS laptop. When I plug the monitor into the laptop via the HDMI port, I go to display settings and click the Detect button. All I ever see displayed is that no monitor was detected. The LG monitor was working for a couple of days but now after an unexpected reboot of the laptop the LG monitor will only display the when the laptop screen open, displays a mirror image of laptop screen.Should I check for drivers or something else?

Laptop display does not detect itself

Hi,

I only have 1 computer (the laptop) and 1 external monitor. The laptop cannot detect its own screen.

So when I follow your steps, this is what happens:

• Go to Settings. (Done)
• Click on System. (Done)
• Under System, choose Display. (Done)
• Under Multiple displays, click on Duplicate these displays and apply. (Done)
• But then I undock my laptop and redock. Re-login, etc.
• Only the external display turns on. The laptop does not turn on its own display. In order to get the laptop display to wake up, I need to follow steps 1-4 again. The settign "Duplicate these displays" does not seem to be retained.

Laptop won't detect external monitor

Hello everyone,

I can't seem to have my Asus laptop identifying my new bought Asus monitor. I am not good with computers and I go on forums all the time to look for solutions. This time simply did not work. Here are the suggestions I found and that I followed entirely like
a child would strictly follow his mother's steps :

[obviously connecting via hdmi cable the monitor to the computer]

- then fn + F8 to activate it => done [duplicated, extended, name it]

- the monitor works fine on its own. I selected on the screen the HDMI option so it should be fine.

- installed the Chipset Intel Kabylake blabla on the asus drivers website [checked the right reference etc] = done. nothing changed

*somebody suggested reinstalling, updating also the graphics card - wanted to but apparently I've already got the latest version.

- Device Manager > Diplay Adapters > Intel(R) HD Graphics 620 [right click] > Properties > ''Select Output'' was supposed to appear in one of the tabs but didn't find any.

- right click desktop > display settings > detect > Message : ''Didn't detect another display''

- right click desktop > intel graphics settings > Display > General Settings > Built-in Display [only option available]. Also tried:

- right click desktop > intel graphics settings > Display > Multiple Displays > Detect - again, none detected.

*At no point when I go to Display on Control Pannel or right click desktop + Personnalize / Display settings, I see a number suggesting that the computers communicates with an external monitor.

Here is what I have :

Laptop : ASUS B9440UA-GV0177R

Windows : 10 Pro

Ram : 16 GO

Cable conection / input : HDMI

Monitor : Asus VZ229

*Precisions : Since I made the terrible mistake of buying an ultra thin portable with basically no ports, i connect everything through the Asus Mini Dock. I'm planning to buy a self powered usb dock but I doubt that is the problem. I simply wanted to mention
this because yesterday, the current mini dock didn't provide enough power for my recording little interface for music / mic etc. The computer, the dock, the cable and the screen are all newly bought so none of them are supposed to be damaged because of long
use.

Sorry for the long message but I am desperate... I thank everyone in advance for taking the time to help me

Thank you and have a wonderful sunny day!
