I sit maybe 2 1/2 feet from my monitor. It's a 21.5 inch screen and honestly, it feels a little large. Yet I see gaming monitors now starting at 23 inch, and 27 inch seems to be the most popular size. So my question is, for folks who own these, especially the QHD and 4K jobs, does it make a difference in your gaming, having such a large monitor, and how far away from it are you? Also for the QHD/4K owners: which is more important to you, pixel density or screen size?
