There is no finite definition of the moniker "HD"...(like Tom mentions above)...Originally Posted by kosmo
I think brands inject the "HD" moniker onto their products at the pixel count in which they feel they can fool their prospective consumers into thinking the consumer is actually getting something tangible from a simple "HD" moniker (that has no finite definition)..
It's all about brands competing to get your money...

HD is a ambiguous term. The one with the most pixels (by definition) should be the "sharpest" per se. However, all pixels are NOT created equal.

Pixel density per square inch will have a lot to do with sharpness/clarity...
These are the HB unit pixel densities per square inch...
The 798 has 31,170.5 pixels per square inch.
The 898 has 17,533.4 pixels per square inch
The 998 has 12,755.7 pixels per square inch
The 1198 has 8,858.2 pixels per square inch
Here is more info from Doug...

Screen size has a big part to do with clarity/sharpness.
PPI = Pixels per inch. This useta be called DPI or dots per inch. You could count the dots on the older CRT displays.
Here is the pixel math for all you high tech red necks!!!!!!
Theoretically, PPI can be calculated from knowing the diagonal size of the screen in inches and the resolution in pixels (width and height). This can be done in two steps:
1. Calculate diagonal resolution in pixels using the Pythagorean theorem:
2. Calculate PPI:
where
is diagonal resolution in pixels
is width resolution in pixels
is height resolution in pixels
is diagonal size in inches (this is the number advertised as the size of the display).
