I hope I am not repeating a previous question. But I am looking at buying a 65 inch tv and the mistubishi is VERY tempting. I think I read that the 06 model (65731) was not able to display the full 1080 lines of resolution? Is that correct? I was also wondering (I checked the best buy where I work and no luck finding the 07 model).. has anyone seen it at their best buy? Should I wait for it instead of getting the 06 model? I just want to be SURE i am getting the best tv for my money. thanks in advance.

I can tell you that I was in CC the other day and they had the 65 inch Mits for $3500 (though there might be 10% off). I would get the 1080P for sure.

Hope this helps.

Thanks. I absoultely want a 1080p tv. I just want to make sure the 65731 outputs a true 1080p image. (I read it had problems with that)
My primary source wil be the HD-A1.. I want the extra resolution 1920x1080 provides over my tv (1280x720).

ALL WD-xx631/731/732/831 sets support 1080p signal input through HDMI, in addition to having Mitsubishi's new 6-color light engine. Last year's models (627/827/927) only accepted up to 1080i (a limitation of the input, not the actual DLP chip) signal input and de-interlaced it to "1080p".

Now if you want to get truly technical, TI's current 1080p DLP chip (the xHD4) doesn't actually have a full 1920x1080p pixel array (it's actually 960x1080). Rather, it shifts the light reflected from the micromirrors back and forth very rapidly by half a pixel to make up for the lack of horizontal resolution, giving the viewer the illusion of full 1080p. By doing this, there is a loss in diagonal resolution that you probably wouldn't even notice unless you throw a test pattern at it. TI did this to reduce cost in manufacturing, and they even admit it in their white paper. The industry's buzz word for this is "wobulation". This is how we get "full-spec" 1080p in our $2,000-ish sets.

This is the case with ALL 1080p DLPs. Same chip, but perhaps different implementation by the TV manufacturer (mostly how the manufacturer's light engine makes use of the chip). The new HD4 720p DLP chip (and also its predecessor, the HD2+) actually has a true 1280x720 pixel array. Funny, eh?
