My 21" EIZO can easily handle 100 kHhz horizontal and 85 Hz vertical
refresh rates at 1600x1280 as delivered by a Matrox G200 graphic card -
with a shielded BNC cable. With the shielded sub-d cable it goes out of
sync and the refresh rates are reduced. I am not an engineer, so I
cannot share anything with you but my own experience. BNC cables are
expensive (I don't know if there are inexpensive ones) and are generally
of a higher quality than sub-d cables. I use BNC on all of my 17"
monitors as well, but it is more important with high resolutions and
high refresh rates. Certainly a G400 MAX deserves one! :-) Someone else
will probably tell you why.

Best wishes,

Bruce
