A bit more info: the Dell is supposed to start shipping on January 23. Lenovo plans to ship in April. ASUS also announced a $799 28" UHD monitor due in "second quarter 2014". The Dell and Lenovo monitors are limited to 30Hz refresh at 4K (fine for programming but not ideal for gaming); the ASUS may do 60Hz but I haven't found a definite answer. Dell is using a TN panel; I could not find info about the display technology of the other two.
