weird misprint on Dell's lcd resolution

15.4 inch WXGA, 1280x800 pixels, 1.0 MegaPixels, 110 Pixels Per Inch

14.1 inch WXGA, 1280x800 pixels, 1.0 MegaPixels, 107 Pixels Per Inch

So which one of the above is wrong? Same number of pixels in smaller area should result more pixels per inch, not less.




(BTW they do have it right in XGA-

15 inch xga, 1024x768 pixels, 0.8 MegaPixels, 85 PPI

14.1 inch xga, 1024x768 pixels, 0.8 MegaPixels, 91 PPI)




It's in the "Help Me Choose" popup when configuring a 630. I was just curious on the exact ppi difference b/t 14.1 wxga & 14.1 wxga+, but questioned the chart's accuracy when I noticed that mistake.

 

I think the 107 is correct. The 110 should be more like 98 I think.

Here is an online tool that I find helpful:

Nice tool, thanks. Yeah, 98 makes much more sense. They are also off on their 12.1 wxga ppi too.

edit: whoa 15.4" 1920x1200 = 161 !! INtense! Since they offer wuxga on a 15.4, I'm surprised they don't at least offer wsxga+ on a 14.1. The latter is actually is significantly less dense.

 

Word. My dream resolution is 1440x900 @ 15.4 (100 dpi), but in a non-Mac, business class machine (matte). Doesn't seem to exist.
