In the same boat here. I use a $400 49 inch curved 4k TV as my monitor along with i3wm and while I waste a lot of the space on screen to perpetually open apps I don't touch, having the ability to look at my todo list or every app I need for a project at the same time has its benefits. I just wish I could lower the height and tilt the TV upwards a bit so I'm not breaking my neck looking at the upper windows.
