I've had this TV for awhile and have set it up using Video Essentials. Before doing so I asked a tech at Toshiba which of the built-in color temps was closest to 6500K. He advised that it was probably the medium. There are Cool (blueish), Medium (neutral), and Warm (Reddish).That is how the owner's manual describes them. Was the tech correct, or is one of the Cool or Warm settings the closest to 6500K? If I change that setting, is it then necessary to set up the TV with Video Essentials again? Thanks in advance for your assisstance. Larry.
