Oh, believe me, the Yanks are not dread (in my house at least) by any stretch of the imagination...:neener:
I nkow exactly from whence you speak, I have a friend who's bought (used) several RPCRTs and asked me to tweak each one in turn, which of course involved moving the monstrous things... What I find funny is how he asks me to do it since he knows it makes an improvement with little to no sweat on his part, yet refuses to watch in anything but full blown ambient light, so his image is never what I would call satisfactory. It's really my own fault though... one day I was watching with him and asked if a certain image was supposed to look like that. He had never seen the convergence issues before. Once I pointed them out he couldn't live with it and I found myself doing full multipoint convergence tweaks on every set he's owned since!:doh: I learned, though, I haven't pointed out to him why his latest set needs a full optics cleaning, so he doesn't care!:innocent:
Anywho, as for your Vizio, I personally wouldn't recommend using anyone else's calibration settings. Chief among the myriad of reasons, the first step in a calibration is setting brightness and contrast, which vary greatly depending on viewing conditions, such as ambient light in the room. At the other extreme, you can hire a pro in your area (or one that travels), but that can run several hundres $.
In between there are 2 other options: #1: you can buy equipment and learn to do it yourself, but that too costs $ and you have to learn. #2 and my recommendation to get started, is pick up a copy of DVE, or Avia, or one of the other calibration disks out there which have test patterns AND teach you how to use them! This will be less than $50, and some experts estimate this will get you 75% of the way there!
