I look at that monitor on a regular basis, but haven't played SH4 on it.
Pretty sharp image although some rather large pixels... 0.27mm.
Mine is a LG L2000 with pixels 0.25 and the difference is not
that big, but it
is a bit sharper.
But I can easily see tiny text on both screens in normal sitting conditions, like 50-80 cm away from screen...
Perhaps you can try a monitor running native 1440 or perhaps lower, 1280?
Note, that if you lower resolution on your monitor, the image will be blurred.
Still you
should take an eyetest.
