Are You Getting All of the HDTV Resolution You Expected?
"Not necessarily, given the results of Home Theater Mag's recent tests of 61
HDTVs. Using test patterns from a Silicon Optix HQV HD DVD, they tested
deinterlacing, 3:2 detection and for the 1080p sets, bandwidth.
Unfortunately, just over 54% of the HDTVs failed the deinterlacing test, 80%
failed the 3:2 test, but the 1080p sets passed the bandwidth test, despite
all but one (Pioneer Elite PRO-FHD1) losing some detail. If a HDTV doesn't
pass these tests, then you're losing at least some visual information from a
1080i signal. Some televisions throw away half the horizontal lines, which
results in a fail on the deinterlacing test, or don't perform inverse
telecine on moving images appropriately, failing the 3:2 test. Of course,
contrast ratio, refresh rate and black levels still contribute to overall
picture quality, but you should take a look at their results to make sure
you're getting every pixel you expected from your new HDTV. " [BJ-M]
