You've got to respect the effort that Gary Merson, a.k.a. the HD Guru, puts into his TV reviews. Thorough and technically savvy, he relentlessly exposes the weaknesses of displays passing through his lab. His latest review is a showdown between two 50-inch plasmas vying for the top, the new Pioneer Pro-111FD and the Panasonic TH-50PZ850U. We've long heard about these 9th generation Pioneer plasmas, the last to come off of Pioneer production lines, so our eyes perked up at the comparison. We won't spoil the outcome of the "two plasmas enter, one plasma leaves" showdown (and that pesky $1500 price difference between the two units is significant), but we will say that the Pioneer lived up to the Kuro name by displaying blacks too dark for the Guru to reliably measure with his test gear. Oh, and the 10th generation promises to be darker still.
