There’s more that goes into making a good display than accurate color, but it’s certainly one of the biggies. Color in a video display may seem like a relatively simple subject, but it’s not. In this Gear Works, I’ll outline the two most important factors in assessing and measuring the color accuracy of the HDTVs we review—color tracking and color gamut. I’ll also show you how we present this in the HT Labs Measures graphics that accompany our reviews. This article will shed some light on what these important measurements tell us about the color accuracy of the displays we test here at Home Theater.

From Sharp Minds

Sharp is a prime mover and shaker in the flat-panel business. The company has been dedicated to LCD technology from the beginning of the beginning—all the way back to the earliest LCD pocket calculators.

If you sometimes get nostalgic for the days of 2-channel audio, you're not alone. Life was simple then. You plugged your CD player in here, your turntable in there, hooked up the preamp to the power amp (unless you were a hair-shirt audiophile with an all-in-one integrated amp) and you were done. Select the source, adjust the volume, sit back, and listen.

Two of the LCD sets in this Face Off, including the Samsung, produce black levels that were unheard of in LCD flat panels until recently. Like the Sony in this group, the Samsung LN55A950 uses clusters of multicolored LEDs as a backlight, together with local dimming of the individual clusters as required by the program material. The LN55A950 is the larger of Samsung’s second generation of LED local-dimming sets.
