I was thinking about what monitor I would like to own in the future (potentially sooner rather than later, but money is always tough). Since the start, I have been saying that I would want at least a 32" 4k monitor to keep the density from getting too high and making things difficult to see/read. However, I recently decided that I want to start using Linux as my daily driver (will get around to it eventually) and only use Windows for gaming. From what I know, the scaling on Linux is much better than Windows. If that is true, then a higher dpi wouldn't be much of a problem. In fact, it would help to make things look smoother, with more information (pixels) being able to be used to basically prevent aliasing.
So in game, would a 27" 4k make sense? a 40" 4k has roughly the same dpi as my current monitor, and I definitely need anti aliasing on it, so ideally, my next monitor would have a higher density, alleviating the need for AA, and making things look smoother overall. And with all of my daily work being done in Linux (potentially), that should remove the problem of UI scaling issues (W10 should get better scaling as well, but that is neither here nor there).
Can someone please attest to the benefits of gaming on a 4k 27" monitor? Does it look significantly smoother (in terms of aliasing)? Does it need AA less so than a 40" 4k monitor? Can you possibly see the pixels (without getting <12" away) or is the dpi high enough to prevent you from ever seeing them? I know that on my ~23" 1080p monitor, during normal use, I can see the pixels in certain situations. Does that ever happen with 27" 4k?
I don't know. It just seems like for purely gaming, higher dpi would make more sense. Completely alleviating the problem of aliasing. high dpi >>>> AA
