This monitor and panel are a new step in the LCD History. Like some of those
announced in 2001 (and we have to admit that it was ViewSonic), out of the
three existing technologies IPS, TN and VA only one will survive, the VA.
This test also shows that this technology is now seriously in the lead. Its
gap with other technologies is so large that we can't imagine going back to
TN or IPS monitors.
