When I did an analysis while shopping for monitors. I realized for the price of 4x 23" monitors I could buy just one 4K monitor. Same results. Less cables. Maybe even cheaper due to less cables. Some of them cost like $20-$50 and they add up.
Doesn't make sense why people still want to go the multiple monitor route. Best argument I see is to hedge against having 1 monitor failing against all 4 failing. I see that argument as being dumb. Monitors have low failure rate. And if it fails, I'd just go buy a new one.
Maybe they aren't trading just one market. For example, if someone is trading 4 different types of markets...one futures, one stock, one forex and such along with any supporting charts related to each of those trading instruments...
Most likely they'll be using a multiple monitor setup considering nobody wants to spend their trading day clicking between different charts every other second to view those different charts when they could just put them all up at the same time on the multiple monitor setup.
Throw in another monitor just for your broker execution platform and associated windows...
Seems ridulous to try to put all that info up on one screen unless you don't mind going to the hospital soon with vision problems, headaches other related health problems from focusing on one monitor and carpal tunnel syndrom due to all the excessive clicking of the mouse to scroll through charts on one single screen.
Yet, be very careful...I've said it a hundred times here at ET. Your monitor setup and how you view your charts will have an impact on the info you see that involves your trade decisions. Too many people underestimate the role their computer setup has on their profits, losses and health (mental & physical).
Also, I've seen a few professional trading offices...each trader had 2 - 3 monitors.
I never really understood why many of us retail traders think we can trade the same way on just one monitor when using a multiple monitor setup is so inexpensive.
