This is a brand new product. Note that it requires a video card that can resolve its wide, hi-res format. You need to verify that before use or you most likely will be ordering a new card whilst the display sits in the box.

What's the difference between Pixel pitch & dot size, or is this Specification even related?.  My Sony CRT has a dot size of .22
I guess I need to do a little home work.

Pixel pitch is the reciprical of dot size...

1/.22mm = 4.545 pixels/mm

4.545 pixels/mm x 25.4 mm/inch = 115.45 pixels/inch

That's better than most!

Any experience with the Dell UltraSharp 2405FPW 24" LCD Monitor?
How does it compare to the 213T or the Cinema displays?

I'm using this monitor docked to a Dell 9300.  This by far the best monitor I've ever used.  It also has 4 USB slots as well as a slot for my CF card.  Getting ready to go out and shoot slot canyons in No Az otherwise would write more.  Bottom line, if your computer can handle it get it.  I got both at the same time that way I knew the monitor would work with the 9300.

I guess I need to do a little home work.
In brief:

Pixel pitch is the commonly used term for the physical size of an RGB picture element (therefore "pixel") in an LCD monitor.

Dot pitch is the commonly used term for the physical size of an RGB picture element in a CRT monitor.

Also, the technologies behind are so different that you cannot equate the measurements. An LCD monitor's pixel is, for all intents and purposes, square. A CRT monitor's pixel may or may not be square, depending on the design goals.

From a user's point of view, these do not appear to be fundamentally different, with one exception:

LCD panels are inherently worse at simulating other resolutions than their "native" resolution. That is, if your LCD panel is a 1024x76 8 panel, it performs poorly at 800x600, and it cannot emulate 1280x960.

A CRT monitor can easily give you lower resolutions than its maximum (similar to the LCD "native"), and often cheat to give the impression of a higher resolution than the dot pitch implies.


Here are some web sources for that home work.
