dimensions of screen?

what are the dimensions of the screen? not the resolution...i want to get a sense of the size of the actual screen. thanks

1.8" off the top of my head

that's diagonal right? what are the dimensions verticle and horizontal

Screens work on a 3:4 ratio, the diagonal is given so it's easy to compute either length.
That ratio was chosen so the diagonal would easily be computed since it would make a 3,4,5 triangle, so you can easily find the horizontal and vertical measures by taking:
(diagonal measure)/5
and then,
(result)*3 for vertical
and,
(result)*4 for horizontal

so:
1.8/5 = .36
.36*4 = 1.44 inches (horizontal)
.36*3 = 1.08 inches (vertical)

Now that you know the basic geometry behind it, never ask that question again.

don't widescreens use 16x9? or something like that?

06-09-2005, 17:01

Yes. Why?

p.s - Fido it's 4:3

tsayin · 06-10-2005, 19:43

Well, you clearly have to know that as well as the diagonal, then.

Huh? The screen is 4:3 not 16:9.

tsayin · 06-10-2005, 20:56

Right, but many screens are now 16:9, so you need to know which a given screen is. Fido claimed all you needed was the diagonal.

Fido · 06-11-2005, 00:39

Oops, got that backwards.
But widescreen screens are wider, you can tell if a screen is widescreen just by looking at it, all you need to know is the diagonal and whether a screen is widescreen or not is self explanitory.
