Calibration display.
I'm sure I'm going to make a lot of friends saying this, but I work for Best Buy. Just like any place, they have people that know what they are doing, and people that are just there to pick up a paycheck. Many of them hardly know the stuff they are selling, but most of them at least know a little bit more than the average consumer (but for 10 bucks an hour and no commision, it's not a dream job for many audio/videophiles). Dispite the apparent ignorance of the associates in the article, the purpose of the display is two-fold. It was originally implemented before Best Buy started performing calibrations. Its original purpose WAS to show the difference between SD and HD. I've worked with Best Buy for a long time and remember when it was unveiled. When Best Buy began doing calibrations, it was a logical choice to demonstrate it on two identical televisions side by side. Since such a display already existed in many Best Buy's, this SD/HD display set-up was chosen to also show the difference between a calibrated and non-calibrated TV. The calibration demo is shown on two identical DVD players using the same connections, but it's pretty boring, so unless they need to demo it, they don't keep it running all day. Usually the associate is eager to demonstrate the differences between the calibrated and non-calibrated TV's, but for the most part, they still display the SD/HD demo so it can perform double duty. I don't know the story of the associate at the store: maybe he was new, maybe he was trying to help out in home theater (which gets ungodly busy at times), I don't know. But I personally have never been told to mislead anyone.
