Hitachi's 42-Inch Plasmas Do 1080

Hitachi bills four new 42-inch plasma models as 1080-line-capable. The following information is for numbers-obsessed videoholics only: The relevant model numbers are 42HDF39 ($2299), 42HDS69 ($2499), 42HDT79 ($2999), and 42HDX99 ($5299). Nominally these are 1080i, as opposed to 1080p, displays though at 42 inches that distinction is negligible. However, it's the vertical resolution that's 1080 lines. Horizontal resolution is actually 1024 lines, as opposed to 1920 in the 1080i ATSC broadcast standard (1920 by 1080). So three of these models are 1024 by 1080, and the lowest-priced is actually 1024 by 1024. Got all that? The difference probably stems from the inherent limitations of Hitachi's highly rated plasma manufacturing technique, which involves vertical channels of pixels crisscrossed by horizontal lines of electrodes. I got a preview at last week's press event in New York though production models will not arrive till later in the year. Up close and personal, the prototype looked pretty spiffy. I could see the dots only from two or three feet. Beyond that the picture looked seamless. The bottom line is that these 42-inch plasmas can show 1080 lines in a test pattern. Try that with a crayon and a piece of paper. Bet you can't do it.
