Independent IT Contractor: I have a 4-wide 1080p screen setup. I keep Slack/Teams on one screen, the semicircle setup means I can only really look at 3 at the same time. I upgraded from 3 screens because I kept having to juggle windows around while troubleshooting someone’s webserver.
Also used this setup when I was really heavy into FFXIV- I like having wikis/alerts open and visible, so one screen for that, the game, discord, and then the last one was just for youtube/netflix.
The thing about IT for older folks is you have to be up for conversation too. Most of the customers I have only get out for church, so if I come out to see them it might be the first conversation they’ve had in days.
