After my laptop unload the battery, the monitor looked like this. Is not the hardware because when I turn on the laptop, it gives me image on this monitor. After the crypto password, the images gets out.

Your display settings screenshot shows resolution 1280x720 however xrandr doesn't report any display with this resolution. Maybe you just need to adjust your Display Settings?

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.
