Windows 10: my monitor starts flickering after plugin

Hi, I'm using windows 11 these days on my ROG Asus laptop. my laptop was working fine for 3 years but suddenly last week after a long update from windows I'm facing with a disturbing problemat first I observed few little horizontal lines on my monitor and also shadow of desktop icons on other pages so I thought my monitor has a problem and I have to change it. but then I found out the problem only will starts when I plugin my laptop. right now the problem is not only few horizontal lines, I will lose 3/4 of my monitor when I plugin the laptop, it will go completely dark or sometimes flickering

Monitor Dim and Flickers

I have a new Dell Inspiron 3668 cpu and running it with my old Dell ST2010 I have run the windows "troubleshoot screen flickering in Windows 10" from Windows help. When I go to task Mngr. it still flickers. So, I uninstalled the display driver as suggested
and then ran the "Check for updates". The problem still remains. Any further suggestions?? My next step is to just replace the monitor and assume Windows 10 will not run it!

 

Screen starts to flicker after logging in for a while

Hello

This is an entirely new issue. My screen starts to flicker after logging in/turning on computer for a while, and/or if I launch an app that uses my Nvidia card (my laptop has Optimus), I'm not exactly sure which of these two causes it. For the first while after a restart, the screen appears fine. The flickering appears on desktop background + internet browser as well, so I'm pretty sure it's not a program compatibility issue. The flickering is not severe (the type that looks like horizontal bars sliding up) but it's an annoyance.

Tried:

• Disabling Windows error reporting + problem reporting service in msconfig
• Restart computer
• Resetting Nvidia global settings to default in Nvidia control panel
• Checking for display drive updates in device manager (all up to date)
• Checking monitor refresh rate (60Hz, can't be changed)

Laptop I'm using:

• i7-4700MQ 2.4GHz
• 1900x1080
• Intel HD 4600 + Nvidia GT750M

Thanks for suggestions.
