Hi I have decided to pick up the Vizio at Costco after all. I am trying to learn how to use DIGITAL VIDEO ESSENTIALS for calibration. I have used it on my current sony and was able to calibrate the audio and it sounds great. Unfortunately I cannot figure out how to calibrate the video portion, I guess all of a sudden I do not understand english that well. Also myself included, for those of you who will be purchasing the Vizio from costco, you may be aware of loud fan noise. Some of us are taking the chance and installing rubber silencers on the fans which are 120mm from nexfan. I received mine in less than one day. I feel that this will control the vibrations of the fans on the back portion of the Vizio. It is very simple to install and can prevent a headache and time with Vizio and also running back and forth to Costco with this giant.
