: You are correct. The Toshiba line-doubling induces motion artifacts that ISF techs have been reporting since the process was initiated on the Toshiba big screens. It has also been reported on this board, but mainly over in the newsgroups. The new Hitachi's and Mitsubishi's are worlds above the Toshiba-And I have heard many people rave about the new XBR-just haven't seen one yet. If you want a soft, movie-like image for DVD, than maybe the Toshiba is OK. But anything else, and the line-doubled image on the Toshiba does not hold up. The line doubler is the only weak link in an otherwise decent TV.

First, you can't complain about a free line doubler, especially when $2000 standalone line doublers produce equal or more motion artifact.

Second, the tack that Mitsubishi (and I'm guessing Sony has taken as well) is the low road: interlaced doubling/interpolation rather than the creation of a progressive-scan image via line accumulation. The advantage of the new method is NO additional motion artifact with NTSC interlaced input. The downside is that it's still interlaced, and as such, is more prone to flicker and will not perform as well for film-mode display which originates as non-interlaced frames rather than interlaced fields. The final problem is lack of true 480p support like the Toshibas, which allow the use of progressive scan inputs from DVD players which offer such outputs, as well as high-end line doubler outputs (if you so desire).

The third consideration is that anyone can (and many frequently do) spout litanies and hyperboles, but that don't necessarily make it so. Millions of people CAN be wrong, as Galileo showed. Take what you read with a grain of salt.

The last thing to consider is that line doubling is a stopgap technology until high resolution or progressive scan sources that DON'T require doubling become plentiful. It was necessary because display technology outpaced broadcast standards, resulting in visible scan lines. Eventually we'll once again be looking at the quality of the display, not the doubler technology it contains.
