If you have connected the laptop to the monitor, can you close the laptop and continue to use the monitor that is operated by the laptop?

Thank you!

Depending on the energy settings, yes.

However, if it is set that the laptop, as soon as it is closed, goes into standby mode e.g. Then don't.

Yes. You have to set this somewhere in the energy settings, otherwise it goes into sleep mode when it closes.

Many thanks for the answer! How can you set this?

If the laptop goes into standby mode, you won't see anything on the monitor. But if you set it not to go into standby mode then you can see the picture on the monitor

Under the power options, then left on the page "Choose what happens when you close the laptop"
