The colour temperature is the colour of light a perfect black-body radiator emits when heated to that temperature. Computer monitors typically have a colour temperature of 5000-9300 Kelvins: 5000 Kelvins is a yellowish-white Cheap Brandon Carr Jersey , 9300 Kelvins is a blue white.

15 Pin D-Sub - This is the shape of connector which plugs into the VGA port on PCs.
MPRII - Rules created by SWEDAC (Swedish Board for Technical Accreditation) to reduce the emissions of a monitor while working. Together with the TCO rules, it belongs to the rules followed by the manufacturers to safeguard the health of PC users.
