"Conclusion:
I'm not sure if I have exhausted my vocabulary of superlatives in this review, but I'll sum it up in one sentence: the Pioneer PDP4280XD is the best flat panel television I've tested to date. (15/07/2007)
After calibration, it fulfills most of my criteria for a reference-level picture quality. Awesome blacks? Check. Enormous dynamic range? Check. D65 greyscale? Check. Saturated but not overblown colours without hue and decoding errors? Check. Smooth as a baby's bottom 24fps handling? Check. Top-notch video processing? Check. No image retention, screen uniformity issues nor posterization? All check."
