What would be the actual WxH dimensions of a 19" widescreen 1440x900 LCD?

[Felecha]

Last time I bought a monitor was 6 years ago, a CRT of course, a 21" Samsung SyncMaster 1100p. Still running, but I sure am thinking of an LCD. If I remember right the 21" meant the diagonal distance, which in my case is really only about 20".

For a widescreen 19" 1440x900, what would be the width and height. Looking at newegg, I figure the WHD has to be the size of the whole thing, not the screen

Like here's one - 17.4?W x 7.9?D x 15.0?H. Do the Pythagorean math, and it would be a diagonal of almost 23"

Check the specs on Dell's monitors. The detailed specs include the height and width of the LCD itself, so pretty much every other monitor with that resolution and diagonal size should be the same. I'm sure some other brands also include that in detailed specs if you can find them.

The Pythagorean theorem does work, but of course it's hard to figure out TWO other variables based on the C^2 part.

I used Dell's information a while back to make up a file with all the standard 4:3 ratios of the angles of the corners, as well as the 5:4, and I may have done 16:10, and then figured out the exact dimensions for several different screen sizes because I wanted to determine the actual pixel density per inch horizontally and vertically. Of course that file's on my home computer and I'm not there.

I meant Pythagorate the 17.4 and the 15.0 and you get a diag of 22.95 .....

OK, I'll look for the Dell spec

1.6x^2 + x^2 = 19^2

10.

Havent done simple algebra in 40 years ... coulda figured it out, having heard before that there is a 16:10 ratio or something in the widescreens?

 

[Lord Evermore]

Dell makes their widescreens in 16:10 ratio, not sure if any others do. It makes the screen a little more functional for use when you're not watching widescreen movies, and just a little bit of letterboxing if you watch a 16:9 movie.

All LCD monitor widescreens are actually 16:10. There are a couple 37-42" HTPC LCDs (they're "TVs" to me but they lack a tuner so technically they aren't) that are 16:9.

TV Calculator is useful for this sort of thing.

not for movies or games, I'm a programmer and often have several work windows open at once. I can switch easily with Alt-Tab, but if I can actually see them at the same time and just go from one to another with the mouse, that would be of real value, enough to entice me if the prices are down below 200 now, with decent newegg reviews

And it looks like Dell has a 20" wide screen but not in a 19

 

[Felecha]

Thinking further here, if I may.

If widescreen is 16:10 and normal is 4:3 and both have diag = 19, then the normal should be something like 14.3 x 12.5. Close enough.

So I would gain width and could see more windows more easily, but the ones I see would not be able to be as "tall". Since a lot of looking at code involves scrolling up and down as well as looking over at something else, I would lose a bit, gain a bit.

But then, I have very good eyes, and dont mind maxing my text by font choices, so the tighter resolution of 1440x900 (I get the idea that there are few if any 19" standards with higher than 1280x1024) might gain back most, if not all, if not more than all of readability.

This is an interesting investigation for me, I dont have easy access to actually look at one. The nearest BestBuy is a long way, and the one time I went, knowing less than I do now, I was disappointed in the widescreen. Only later did I understand that there was one computer driving a bank of monitors, all at the same 1280.

So I'm poking around at the theory.

Thanks to all

The aspect ratio and native resolution almost always works out to produce square pixels, IIRC. I guess it's pretty safe to simply divide the horizontal lines by the vertical lines (e.g. 1440/900) to arrive at the aspect ratio.
