Home desk is L-shaped. 6' across main desk part. L-return on my left, where I spread my
books and papers. There is a dresser behind me holding essentials like a fan, and my Keurig coffee maker. Essentially turns it into a 'wraparound.' (Book cases line the wall to the right, with a gap between the desk edge and book cases of just 2 feet. Nothing needed is very far away.)
The 3 screens are 'curved' screens, forming an arc across the 6' of desk (Sometimes I connect a 4th smaller screen below the center of the 3, and put some forest/stream/birdsong type stuff on to give me a relaxing ambience.)
The work desk is similar - a
big wraparound "U," one leg of the U in front of me, the main part to my left, and the othhr leg of the U behind me so I can spin around and grab files, etc. from the drawers.
3 screens at work are a little "up higher" and in an arc, with the 4th screen sitting right below the center one of the 3 upper screens. (This keeps my eyeballs "up" and neck straight, so I don't suffer neck strain.)
In both home and work, I can see everything with just a wee turn of the head.
(Naturally, I have a Keurig coffee maker on the "U" leg behind me at work too, so I don't need to
travel anywhere to grab the next cup..!!)
I spend a lot of time at desks. They are set up for functionality without strain and drain.
