Windows 10: How do I switch off the display on my laptop when I close the lid

I use an external monitor attached to my laptop. On my previous installation I had a 17inch laptop running Windows 10 professional and linked to a Dell 24 inch external monitor. The setup was that if I closed the laptop lid its display was switched off and the display shown on the Dell utilising the full screen.I am now using Windows 11 on a 15 inch laptop but I cannot find any setting which will allow me to set the laptop to switch off if I close the lid. The other problem is that if I setup the display settings to only use the external monitor it is shown using the full size of the screen

Laptop, Dual Display, Lag with closed lid

Hi,

I just bought some monitor to use with my Dell laptop and connected it through the HDMI port of the second graphics display. The problem is that when I close the lid, the laptop automatically turns off the laptop display and stops using the internal video card which leads to minor lag when using the new monitor with only the second graphics display being active.

Obviously the solutions are:
1) Somehow force the internal video card to still be used
2) Stop the turning off of the laptop display when the lid is closed (I don't have such option in control panel -> power options)

Any ideas how to go fix this besides not closing the lid at all?

Have you tried right clicking the battery icon in the taskbar, then choose Power Options. On the left side you should have a menu saying "Choose what closing the lid does". Click that and choose what you want.
