It's worse than that.....you also have to take the "aspect ratio" into account. Using the diagonal only made sense as long as all TV's had the same aspect ratio.

I wish TV (and monitor) vendors would come into the 21st century and drop the danged diagonal measurement and state the spec as LXWXH. Or at least include that info as well as the diagonal.

I agree...... I have a custom made cabinet in my den and I'm constantly checking out new TV's for it while forgetting that it will only accomodate a maximum Height and Width dimensions regardless of screen size.......
