What is color temperature and what does it affect?
Some monitors have the capability of selecting or adjusting for the ‘color temperature’ of the display. NEC AcuColor on the 4/5/6FG series of monitors is one example. The terminology refers to the spectral output of an ideal black body source at that actual physical temperature. It essentially sets the appearance of a white screen. For example, a color temperature of 9300K will appear blue-white while 6300K will appear yellow-white. It only affects the relative balance of R,G,B and has nothing to do with refresh rates or anything performance related.
