When I was doing this 10 years ago, I loved my monitor setup.

I did the 20-30-20, Portrait-Landscape-Portrait thing where I had 2x 20" Dell 2007's in portrait mode on the sides and a 30" Dell 3007 in the middle. The 2007's are 1200*1600 resolution, while the 3007 was 2560*1600. They have the exact same dpi and the height of the 2007's in portrait exactly matched the height of the 3007.

This is not my photo, but the setup looked exactly like this: http://3dalchemist.com/images/lcds/l...-authoring.jpg

It was great for multiboxing WoW as I just split my minions to both sides and gave each of them 1/2 of a 20" monitor. So they ended up on a 15" 1200*800 resolution which was even good enough for the occasional collection quest without having to screen swap them. (Although having 2 of them on the left and 2 on the right may not have been ideal in terms of having to hunt back and forth with your eyes to find something)

Back then most web pages were still optimized around people with older monitors, so web pages were 800 to 1024 pixels wide which was great on my 2007's in portrait mode. Nowadays I think websites are optimized around older cell phones and 1366x768 laptops. So I'm finding a lot of web pages where I need to scroll horizontally on my side monitors now.

Some years ago my Dell 3007 died and I replaced it with a Acer Predator 32" 4k monitor. I love the 4k resolution and the size is almost the same as my old 30", just stretched 2" wider. But now I have a dpi difference between my main monitor and my sides. You can somewhat mitigate that with dpi scaling, but dragging windows between monitors always messes them up.

About 2-3 years ago I tried replacing it all with one of the 38" ultra-wide monitors, But at 3480x1600 that was much smaller than my triple monitor setup. It had the height of a 27", but about 2x as wide as a typical 27". I liked the width, but wanted more height. I found I actually missed the bezels as that was the way I split up much of my work - email on left, work area in the middle, chat utility on the right. Overall, I hated the 38" ultra-wide, so that ended up as my wife's new toy.

I'm looking to upgrade, but I don't see any sort of way to do a more modern
Portrait-Landscape-Portrait thing (everyone stopped making monitors that aren't 16:9 widescreens).

Any thoughts or recommendations? I'm not really limited by budget, or desk space.
