The ST60's picture fidelity is outstanding. It compares favorably to the best TVs I've ever reviewed, with superb, inky, deep black levels; ample shadow detail; accurate color; and very good video processing. Its bright-room picture is also top-notch, thanks to an antireflective filter that far surpasses that of the step-down S60 series.
As usual, if you have an extremely bright room, you may want to choose an LCD instead, but for nearly every normal room, this plasma is plenty bright -- and has the characteristic near-perfect uniformity and off-angle performance of its breed. Its biggest flaw is 3D picture quality, but I don't even consider that important enough to include in my consideration of its overall picture quality score, which is a solid 9 out of 10.
