They have the same vertical space. And the pixels are not a different size. As in, the pixels arent squished into a smaller vertical space. The phyiscal height is the same, but the width is different (thats what the 15.1" vs 15.4" accounts for).
Ignoring pixel-sizes, both the physicial widths and heights are different. The 15.4" and 15.1" measurements come from the hypotenuse (the longest dimension - ie. corner to corner), not the width singly.
Believe it or not, a widescreen 15.4" has less physical screen area (in centimetres squared) than a regular 15.1". The 15.1" screen has a more square shape (4:3) so the diagonal measurement has the tendency to be biased more efficiently, so comparing both diagonal LCD figures are meaningless without comparing physical X and Y measurements.
I could say I have a 100" screen, but it could still be only 1" tall, depending on how long it is. The diagonal measurement itself, on its own, is misleading.
Even the 17" widescreen only has the same physical screen height (9") as a standard 15.1" LCD.
So, the pixels are indeed more squished vertically on a 15.4" widescreen than a 15.1" by nearly an inch (0.8"), and therefore a comparitively similar vertical resolution on a 15.4" widescreen will be even tinier (smaller) than on a 15.1". The LCD diagonal figure is misleading in these cases, as the greater width of the 15.4" brings out a higher number even at the expense of the vertical height of a 15.1".
The physical height a of a 15.4" widescreen is slightly smaller than a standard 14.1" screen. So, in other words, a 15.4" widescreen is effectively a 14" screen but with the width extended.
That's why I'm going for a 17" widescreen, as I don't want to lose the height of a 15.1", but still want to have more space horizontally.
