> The only question would be the sheer number of pixels on the screen. Which on Linux is a big, big question. My experience is that a 2x2 array of 2560x1440 displays is simply not reliable under Linux. The same worked fine with Windows. The total number of pixels is one factor that seems to trip up Xorg (or something); the above setup had a total resolution of 5120x2880, yet a 1x3 array totalling 4320x2560 worked fine. This was last year, on multiple machines with various graphics cards (but just one card in a given machine). So I don't know why, but it seems that somewhere between 4320 and 5120 linear pixels, or between 11 and 15 total megapixels, Xorg or some other part of Linux (but probably Xorg) has problems. This Asus screen is 3840x2160 which means two of them together (16.5 MP) will likely not work (there's a chance if they're oriented vertically so the max linear resolution is 4320), and three in any configuration is very likely to fail. Using many displays and getting very high resolution on Linux has been a bad situation for a long time now. Some hardware configurations just won't work (but are fine with Windows); others will hard-lock sometimes; still others will mostly be OK but once in two weeks freak out and spew artifacts everywhere. It's a real mess, and nobody seems to "own" fixing it.
