So, what happens when you connect the external monitor? Did you try connecting the same laptop to another monitor/connecting the monitor to another computer?

My external monitor works fine with my other laptop running the same OS. So the problem is no about the monitor. When I connect the G15 5520 to monitor ,nothing happens

Did you try connecting via both VGA and HDMI (if both of them are available)? What exactly happens when you connect the external monitor?

I tried only with hdmi. Well, as I said when I connect the hdmi to external monitor, the monitor is just black...It's like it is not connected.What do you suggest?

Ok I changed a driver from "software and updates" and no the external monitor works as I expected.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
