This new format sounds interesting. I personally have been using a fairly cheap 48" 4K TV as my primary desktop monitor for a number of years, as that combination is effectively like a 2x2 arrangement of normal sized 1080p monitors.

It works well, except that it was basically impossible at the time to find a graphics card that could drive it reliably at 60Hz (I tried both a Radeon R9 270X and an nVidia 1060, both of which were newly released at the time). The 1060 is better in that it actually manages 60Hz, but only in YUV422 mode (which is mostly fine as I primarily do black-and-white code editing) and if I want to avoid YUV fringing, I need to run at 30Hz. The Radeon required me to use an external DP-to-HDMI adapter, which worked, but then I hit driver redraw issues, so I stopped using it within about a week.

But in any case, the biggest problem with a set-up like this is that it's so hard to go back to using a small monitor afterwards. Even dual-screen feels cramped afterwards!

I use a 42" monitor and it's never worked as well as I wanted it to.

I wanted to have 16 windows open at once so I could see all the spreadsheets, text files, folders, pictures relevant to the legal matters I was working on. The 3840 x 2160 pixels lets me do it, but there are drawbacks and limitations:

1. Only the windows in the center of the screen are easy to perceive. I have to turn my neck or my eyes to bring the other windows into my attention, or sit further away from the whole screen, as if I had a smaller monitor.

2. The Mac menu is all the way up the top left. That makes using any app in any window that isn't top left difficult because I have to keep sending the mouse away long distance.

A friend got something instead which is better: Two very wide and not very tall monitors, which he arranges vertically stacked. What makes this so successful is that each monitor has its own menu.

I wish I could accomplish the same thing by telling OSX to split the screen horizontally across the middle so I had two menu's too.

I want to emphasize the other comment:

> The other thing that's absolutely essential for using these larger format monitors is window management software and in general a more keyboard/macros focused workflow.

My 4k 39" screen really, really drove me to use keyboard shortcuts. By default on Windows, hitting Windows+Number will take you to the 1st/2nd/3rd/etc program in your taskbar. I use AutoHotKey to take this further: CapsLock+Number and CapsLock+F1-F12 also take me to predetermined programs. I install websites as Chrome apps (chrome://apps/) in order to make going to Gmail/Calendar/Github faster. (I use 7+ Taskbar Tweaker to hide the labels so they don't take over my taskbar.) I also use this script: https://www.autohotkey.com/board/topic/79338-simple-window-p... which makes window management (resizing, centering, moving, etc) much easier. I also use Vimium and this program https://github.com/zsims/hunt-and-peck - now my hands almost never leave the keyboard.

I encourage you to spend some time optimizing your setup. It really, really pays off. The powerboard on my TV-monitor has broken 3x now - and each time I've repaired it/replaced the part because I like my setup so much.
