I bought a 27" UHD Monitor and was very happy with it. I got the same monitor for my workplace but now I'm back to the previous 24" one (only HD unfortunately).

I bought a 27" UHD Monitor and was very happy with it. I got the same monitor for my workplace but now I'm back to the previous 24" one (only HD unfortunately). Not sure why but it was too big in that office / for the tasks that I do. There can be such a thing as too much physical interaction. If I have to turn my head constantly, and more importantly find everything again with the eye, it's straining and it gets unproductive. Even at home where I'm happy with the monitor, I often have these huuuuge blank areas on the screen (that emit a lot of light), for example while typing this comment. But other elements (such as the browser's tablist) extend uncomfortably to the right, and typically I'm switching between the rightmost tabs.
