Am I the only one who thinks monitors turned to portrait looks dumb and can’t possibly be more useful? The number one reason people give when I ask is that they can fit more code on the screen. I don’t know about you but I don’t have the ability to glance at an entire screen of code in portrait or landscape and understand it immediately.

I don’t mind a portrait screen for terminals, but other then that I don’t feel the need for it, multi monitor sure, too many programs running and not enough screen space.

I have one landscape and one portrait. Porteait one has console/compiler output pinned to the bottom. I would prefer just one huge screen landscape tho

A good tiling window manager like stumpwm and portrait monitors become very useful.

Its not about vertical space its about horizontal.

Your code never uses your landscape width. But the space left is to small to fit another program.. Vertically it stacks great.

Then for pair programming having it portrait is really nice because you look at one part and your pair fellow can look at a completely different part because of the big window.

Would I use it as single screen? No.
Do I miss it in a dual or tripplescreen setup? Hell yeah

It's bad for you neck too.

I have a couple of screens (all landscape). I have different resolutions on a square 1280 x 1040 for reading instructions and tutorials, a 27 inch I mac for coding on and finally a 1920 x 1080 landcape monitor for outputting my work too.

I'm getting old and the smaller res screen really helps as my eyes are now defunct. It has the effect of making the text seem bigger in comparison to the other screens. The MK 1 eyeball now needs reading glasses, something I've never needed before.

But in principle, I have one to read from, one to work in and one to see the output on. I also test on my windows 10 pc and android devices that I have knocking around the house.

I have a triple monitor setup at work, two in landscape and one in portrait. I do all of my dev work on the landscape monitors while on the portrait I'll flick between consoles or HipChat. It's excellent once you get used to it.
