There are plenty of good flat 27" monitors out there.
Not VA. Those are all curved, AFAIK.
Hahaha you think your eyes can even tell the difference between 240 or 120. You poor fool falling for the marketing hype. You're probably too young to remember that 30 used to be the standard and 60 is perfectly fine even today.
Plenty of gaming sites have looked into the benefits of high-framerate displays, so I won't rehash those arguments here. If you're unfamiliar with them, you'd do well to educate yourself before advising others.
P.S. Nothing
really used 30 Hz. TV used ~50 or ~60 Hz, but would refresh only the even/odd scanlines on each pass. However, TV cameras would capture each of those fields at a unique timepoint, rather than extract them from ~25 or ~30 fps progressive-scan captures. When digital video became inexpensive and you'd see such video on an interlaced TV, it would look almost jarring.
And as far as film is concerned, 24 Hz is a
limitation filmmakers
worked around. It wasn't
perfectly fine for everything they wanted to do, but they learned to live within its limits.
