Eli5: why do retail stock traders have several screens and is it necessary to have more than 1 to trade successfully?

Question

I see so many retail stock traders having 3-4 different screens showing different graphs and charts Is it necessary? It looks so fancy and complicated. Won’t a trader using only 1 screen be successful?

I use to run 3 large 4k monitors. Over the years, it’s dwindled down to a single qhd laptop. Sometimes I’ll attach a small second monitor. I realized all those screens is just info overload. But maybe some people have strategies where that is useful.
