One point I forgot to make: this is from the point of view of someone using the TV as a PC monitor. The calibration is only valid when the TV is connected to the PC, because all the profiles are applied on the graphic card and the operating system. If one needs to calibrate the TV for independent use, then it is a completely different problem (that probably requieres different software more than a different probe). Regards, Guillermo
