Why are 17" TFT monitors 5:4 ratio?
Mar 7, 2002

I've been having a discussion in rec.photo.digital argueing that 17" TFT monitors should not have an optimum resolution of 1280x1024 (5:4). I say to display an image properly they should be 1280x960 (4:3).

It's my contention that as monitors are always 4:3, the resolution should also be 4:3 because viewing an image with the resolution set to 1280x1024 (5:4) would make the image appear vertically squashed?

I'm having a job trying to convince others that this is the case.

I've used the following arguement:

For argument and convenience sake, let's assume the picture you're viewing on your monitor fills the window in Photoshop or PSP etc exactly to its top and bottom edges. You are viewing it at 1280x960 (4:3 ratio). You now switch the resolution to 1280x1024 (5:4 ratio), the image no longer fills the viewing window from top to bottom as it did with 1280x960 but the width is still the same. Unfortunately, this means all images displayed at 1280x1024 appear vertically squashed as they fill the same width of the screen but appear to have less height, even though the image dimension haven't actually changed.

Therefore, the optimum 1280x1024 of a 17" TFT is not ideal for digital
imaging, 1280x960 (4:3 ratio) should be used for perfect reproduction of
the image.

Your comments would be appreciated.
