Regarding K20/200D screen

I had the impression (from what was said in some threads) that this screen was supposed to be high resolution but my maths don't add up:

Am I right in saying that there are 3 dots per pixel, not 3 pixels per dot?

And that hence, the screen has 320*240 = 76800 pixels, which equals 320*240*3 = 230400 dots which makes it a normal (ie "low") rez screen?

From watching the video on youtube from pentax about the k20D, it doesnt look to be all that different from the screen in the k10d at the moment (apart from physical size of course)

Yeah, it just the same resolution screen 320x240.

That's why they use "dots" in the specs as opposed to pixels. So what they really mean is sub-pixels = dots.

on Pentaximaging site, they wrote, I quote:

The K20D features a large 2.7 inch color LCD monitor with approximately 230,000* dots resolution
* One dot equals 3 pixels.

so this mean 3*230000 = 690000 pixels. That is if they didn't made a mistake in the announcement.
The site isn't working for me anymore, here is the google cache
