Primary screen keeps flickering on connecting projector display

us flag

I am running Ubuntu 22.04 in my laptop. When an external display(projector) is connected using an HDMI connector, the primary display ( laptop screen) keeps flickering between a black screen and the display output. Choosing external display only I am able to see the screen. Mirror and join display options get the flickering issue. I was using this projector without any issues before. This started recently. The projector is working with other systems.

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.
