Hello Robertb.

Today I was once again salivating and re-reading specifications for the 6" and 5" models and there is something that bothers me.

On 5" model page
http://www.astak.com/5Ebook_Reader.html
there is:
Resolution: 800 x 600 pixels, 170dpi, B&W, 4 grayscale

On the 6" model page
http://www.astak.com/6Ebook_Reader.html
I read EXACTLY the same dimensions
Resolution: 800 x 600 pixels, 170dpi, B&W, 4 grayscale

So I have started OOo Calc and I have played wit the numbers a little bit.
For the 6" display with 800x600 pixels the resolution is 166dpi, just like with all other readers.

What is unclear to me, what is the resolution or pixel size of the 5" model.
If we keep the same resolution 166dpi we get 664x498 pixels
or, if we keep pixel size 800x600 we get exactly 200dpi resolution.

So how is it with astak 5" model?
What is the real dpi?
