Adaptive gain control for 7UY

Plasmawholesale.com has the following description of adaptive gain control for the PHD7UY (also note that they are offering the set at a price even below 1800plasma):


"High-Contrast Images with a High S/N Ratio - Adaptive AGC

Our previous automatic gain control (AGC) detected the brightness level of the entire image, then boosted it as necessary. This had a drawback, in that it tended to increase noise and black-out parts of the image where the video signal did not require boosting. Adaptive AGC raises contrast while suppressing noise by detecting and boosting only the image edges. Note: The default setting for the Adaptive AGC is OFF."


Those who have experience with the 7UY - Are you setting the Adaptive AGC to on or off?


Thanks.
