| So dell has their new 27" monster of a screen on sale.

Thanks for the heads-up.

| The old 27" was a 16:10 1920x1200 PVA panel.
| 
| The new 27" is a 16:9 2560x1440 IPS panel.  It is essentially a 30"
| 2560x1600 IPS panel with the bottom 10% cut off.  So same width, slightly
| less height.

Interesting.  By my trig, (assuming 27" and 30" are exact), the 27"
screen should be 23.5" wide and the 30" screen should be 25.4" wide.
Sloppy measurement of my 30" confirms the second figure.

| It is on sale today for $799.  Given the cheapest I have seen the 30"
| version is $1499, $799 for 90% of the 30" is pretty impressive.

A 30" was on sale at Dell for $999 perhaps 3 days ago.  Dell has
several 30" monitors at different price points.  The difference (as
far as I noticed is how many different kinds of inputs they take and
whether they are willing to scale.

| Lots of pixels for applications, although perhaps not the worlds best
| screen for HDTV and video given it has too many pixels to match HDTV
| resolution.

On a raw pixel/$ basis there are way better choices but I would not
give up my 30" monitor.

The latest iMac has a 27" monitor with resolution similar to this one.

================

I wrote a little bc script to figure out dimensions of TVs.  I plugged
these monitor numbers in.  Run this script by saving it to tv-trig.bc
and then running the shell command: bc -l tv-trig.bc

Notice that a 4x3 image on a new 32" TV is about the same as on an old
26" TV?  The key is to look at the height (last column)

define stats(diag, hr, wr) {
	auto dr;
	sc = diag / sqrt(hr^2 + wr^2);
	print diag, "\q ", hr, "x", wr, " ", hr * sc, "\qx", wr * sc, "\q\n"
}
junk = stats(26, 4, 3)
junk = stats(32, 16, 9)
junk = stats(40, 16, 9)
junk = stats(42, 16, 9)
junk = stats(50, 16, 9)
junk = stats(60, 16, 9)
junk = stats(32, 4, 3)
junk = stats(27, 2560, 1440)
junk = stats(30, 2560, 1600)
