Technical terms and their importance to the end user:

Display Information:

Max User Adj. - Basically this spec states that this is a 15" LCD panel, and gives the dimensions of the viewing area (304.1mm x 228.0mm).  For LCD displays, the size (15") corresponds with diagonal of the viewable area whereas for regular CRT monitors, the size corresponds with the size of the monitor's tube (and not viewing area).

Pixel Pitch - The pixel pitch or "dot pitch" of a monitor determines the size of each screen pixel.  This pitch is the size between each pixel element (for an LCD display, there are separate red, green, and blue pixels) and the next pixel component of the same type.  Smaller pixel pitches result in enhanced image quality (the overall sharpness of an image is increased).  Personally, I was not too impressed by the pixel pitch on this monitor, as a 0.297mm pixel pitch is rather on the high side for today's monitors and LCD panels (also keep in mind that LCD panels do tend to have larger pixel pitches than their CRT counterparts).

Viewing Angle - Typically, if one views a LCD monitor from the sides or from the top, the overall perceived contrast and brightness of the monitor decrease.  In addition, the colors perceived by a viewer may be off.  The viewing angle is the angle away from the monitor where colors remain unchanged as well as where the brightness and contrast are sufficient for viewing.

Contrast Ratio - The contrast ratio measures the difference in the intensity of light between the darkest black and lightest white.  The contrast ratio affects the readability of a LCD panel, with higher contrast ratios allowing for better representation of colors and overall image quality.  The contrast ratio on this LCD panel was 350:1 which is a rather typical value.  Higher end LCD panels support contrast ratios of 600:1 or better.

Pixel Response - Personally, I feel that this specification is the most important for a LCD monitor.  The pixel response is the amount of time it takes for a pixel to turn off or on.  LCD monitors with higher pixel response have significantly higher amounts of "ghosting" (where the monitor can't keep up with fast moving action).  For gaming purposes, it is typically recommended to have a pixel response of less than 25ns. 

Horizontal/Vertical Scan Freq - These two specs dictate the "refresh" rates of a monitor.  The usual concept of refresh rates correspond with the vertical scan frequency.  Keep in mind that LCD monitors do not suffer from flicker (and refresh on a per pixel basis, rather than per line), so higher refresh rates on LCD monitors are not as important.



Consumption - This a measure of the amount of power that a monitor consumes.  The Hitachi CML152 is extremely power efficient in comparison to other monitors and LCD panels.

Heat Dissipation - This is a measure of the amount of heat that this monitor gives off.  85 BTU is relatively low for a LCD monitor (and this monitor is relatively cool to the touch).

Integrated Power Supply - This is one of the nice features of this monitor, where there is no need for an AC adapter or "power brick."  The power supply of this monitor is directly integrated into its guts and as a result allows for the use of a normal power cable.
