Does anyone have comparative experience with PC monitors of roughly 27" size? I'm just trying to figure out how much of a useful improvement 4K is over 1440. Since I currently have a 1440 monitor, I know that the step from 1080 to 1440 is pretty worth it. I'm also watching some Youtube videos with camera footage lately and they look gorgeous, although that footage is originally 4K and thus oversampled, so it will of course look a bit better than native 1440.
