    Good information. My Visio TV/monitor was so far out of whack when I received it that immediate setup was needed. Too much red and everything looked too bright. I eye-balled the setup and looks great. The Visio has a built-in grey scale pattern that you can use for 80% of setups. Getting your hands on good test patterns is another expense.

    I tried the cheaper colorimeters or spectrometers but the supplied SW just did not cut it. The SW routines were consumer oriented and way too basic/ automatic. "Does this look brighter or darker to you?". The resulting picture was not optimum. I need SW like the pros use where you make an adjustment on the monitor and SW displays the RGB and white/ black gains. Or overlays the colorimeter output on a color wheel to indicate the monitor visual output while adjustments are made in real time.

    But a little tweaking can go a long way in improving the picture quality.
