I use a 27" 4K IPS @ 144Hz. I upgraded from a 60HZ 1440p at the same size, and it was a massive upgrade. Once you go to this pixel density, it's hard to go back. Similarly to 120Hz, if you do any sort blender / modeling, or other graphical applications - it's a completely different experience.
Both the pixel density and refresh rate, coupled with a backlight onto the wall, reduce the eye strain so much. I can't imagine sitting a foot away from a TV.
