I've always wondered about that resolution. It's what I would call
I'm assuming you have a 16:9 TV (otherwise, it doesn't even fit the
almost-square description). If so, pixels would be square if the ratio
of the X resolution to the Y resolution is 16:9. Doing some math:
1360 / 16 = 85
85 * 9 = 765
So, technically, 1360x765 resolution would be square pixels on a 16:9
display device. In reality, the difference is within rounding error for
DPI/DisplaySize/font size calculations, so it won't make a difference
whether you use DPI (which is close) or DisplaySize (which would be exact).
So, does anyone know the story behind the choice to use 1360x768 for
some devices (seems to be especially LCD's and Plasmas)? It's not
important, but I finally had a reason to mention the issue in case
someone out there has some info and a willingness to teach me...
