Re: SONY Bravia W4000
Συγκριση W4000 με PZ80 σε SD...
Standard-def content looked rather good on the Sony KDL40W4000. On top of excellent blacks and colours, the LCD HDTV did a better than average job of upconverting 576i video signal to fit onto its 1920 x 1080 high definition screen. Sufficient detail and sharpness were preserved without introducing excessive halos (which would have suggested overzealous/ undefeatable edge-enhancement). We could tolerate sitting as near as 6 feet away from the television, as long as the quality of the source was not too poor and the aspect ratios were matched (i.e. [4:3] for 4:3 material, and [Wide] for 16:9)....
Without the aid of edge enhancement, the scaling quality on the Panasonic TH42PZ80 plasma HDTV was mediocre at best, so perhaps there is a case for sprinkling in a touch of overenhancement (by increasing [Sharpness] a couple of notches) for standard-definition content. We were also disappointed by no improvement in posterization in spite of the full HD native screen resolution, although these usually only reared their ugly heads with poor source (low bit-rate, highly compressed broadcast material) and during fade-in/ fade-to-black...
