Test Bench |
With Dark Room backlight and 6,500 K color-temp settings, the 747i's grayscale tracked within ±590 K of 6,500 K from 30 to 100 IRE - below-average performance. Red, green, and blue adjustments in the user menu improved performance considerably, resulting in ±252 K tracking from 20 to 100 IRE. Color decoding measured +5% red on HDMI and -5% green on component-video inputs. 1080i/p and 720p test patterns were fully resolved via HDMI and component inputs. Screen uniformity was average, with a slight darkening visible on gray full-field test patterns (but not regular programs) and a noticeable drop-off in contrast when watching from off-center seats. As expected given the set's HQV video chip, it breezed through deinterlacing, film mode, and noise-reduction tests on both the standard- and high-def Silicon Optix HQV test discs. Full Test Results |
Other adjustments include horizontal/vertical image position; cropping (which turns overscan on and off); and noise reduction. A submenu includes black-level expansion, a white peaking limiter, and contrast enhancement. I didn't find these useful - especially black-level, which eliminated shadow detail from images.
Although the 747i's numerous picture adjustments are a good thing, its onscreen menu leaves something to be desired. After I hit Menu on the remote, a rolling 3-D hexagon popped up onscreen. This object's facets contain various submenus, and after a few fumbling attempts I eventually learned to navigate them with the remote's arrow keys. Not exactly user-friendly. What really threw me, though, was when I selected a facet for adjustment and its color outline switched from green (the universal symbol for "proceed") to red. It was totally counterintuitive; my first time out, I had no idea what adjustments I was making to the TV! And without numerical indicators on the adjustment sliders, there was no way to record what picture settings worked best for future reference.
PICTURE QUALITY After a few tweaks to the 747i's User 6500 K mode (see Test Bench - Coming soon), I launched into my viewing regimen. Since this set's main selling point is high-quality deinterlacing and upconversion, I started with DVD and cable TV. DVDs had a crisp, stable appearance that held up exceedingly well in fast action scenes. The upconverted picture looked about as good as that from my Toshiba HD DVD player, and that's saying a lot. Although analog cable stations never look a fraction as good as high-def, the set's noise reduction helped smooth the picture without robbing it of desperately needed detail. To my memory, CNN Headline News never looked quite this good on a bigscreen LCD.
