G
Gamma
Screen luminance as a function of video voltage approximately follows a \
mathematical power 
function of the input video signal, the exponent of which is called gamm\
a.
 
Grayscale
An achromatic scale ranging from black through a series of successively \
lighter grays to white. 
Such a series may be made up of steps, which appear to be equally distan\
t from one another. If the 
Analog/ Digital converter is 8 bit, then the monitor can display at most\
 2
8 = 256 levels. For a color 
monitor, R.G.B. each color hads 256 levels. Thus, total color can displa\
y is 256x256x256= 16.7 
million.
 
 
H 
Hue
The main attribute of a color that distinguishes it from other colors. F\
or example, a color may have a 
green, yellow, or purple hue. Color defined as having hue are know as ch\
romatic colors. White, 
black, and grays possess no hue.
I
IPS (In Plane Switching)

Glossary
 
A technique of improving the viewing angle of an LCD where the liquid cr\
ystal molecules are 
switched in the plane of the LCD layer rather than vertical to it.
 
L
LCD (liquid crystal display)
A display composed of liquid crystal suspended between two transparent s\
heets. The display is 
composed thousands of pixels which can be turned on or off with electric\
al stimulation. Thus, 
colorful images/texts can be generated.
 
 
Liquid crystal
The compound found in liquid crystal displays. Liquid crystal reacts pre\
dictably when electrically 
stimulated. This makes it the ideal compound to turn LCD pixels on or \
off. Liquid crystal is 
sometimes abbreviated as LC.
 
Luminance
A measure of the brightness or luminous intensity of light, usually expr\
essed in units of Candelas 
per square meter (cd/m2) or foot Lamberts. 1 fL=3.426 cd/m2.

N
Nit
A unit of luminance equal to 1 cd/m2 or 0.292 ftL.

PerfecTune
PerfecTune is industry-leading, proprietary Philips testing and algorith\
m technology for display 
adjustment and fine tuning, an extensive process that ensures ultimate p\
erformance in compliance 
with a standard four times more stringent than Microsoft’s already hi\
gh Vista requirements from 
each and every monitor that leaves the factory–not just a few review \
samples. Only Philips goes to 
these lengths to deliver this exacting level of color accuracy and displ\
ay quality in every new 
monitor.
Pixel
PICture Element; the smallest element on a computerized CRT or LCD image\
, and hence a display.
 
Polarizer
A light filter which only allows light waves of a certain rotation throu\
gh. Polarized material with 
perpendicular filtering is used in LCDs to enclose the liquid crystal. T\
he liquid crystal is then used 
as the medium which twists the light waves 90° in order to allow the \
light to pass through or not.
R
Refresh rate
The number of times per second the screen is refreshed or redrawn. This \
number is usually stated 
in Hz (Hertz) or cycles per second. A rate of 60 Hz is equal to 60 tom\
es per second.
 
S 
 
SmartContrast 
Unique technology that dynamically analyzes displayed content and automa\
tically optimizes a LCD 
monitors contrast ratio for maximum visual clarity and viewing enjoymen\
t, stepping up backlighting 
for clearer, crisper and brighter images or dimming backlighting for cle\
ar display of images on dark 
backgrounds. For monitors with SmartContrast, contrast ratio achieves 30\
00:1, the highest 
available today in a desktop LCD monitor.

inesses that minimizes 
costs and maximizes IT staff efficiency by remotely controlling key disp\

.
sRGB 
 
sRGB is a standard for ensuring correct exchange of colors between diffe\
rent devices (e.g. digital 
cameras, monitors, printers, scanners, etc.)
Using a standard unified color space, sRGB will help represent pictures \
taken by an sRGB 
compatible device correctly on your sRGB enabled Philips monitors. In th\
at way, the colors are 
calibrated and you can rely on the correctness of the colors shown on yo\
ur screen.
Important with the use of sRGB is that the brightness and contrast of yo\
ur monitor is fixed to a 
predefined setting as well as the color gamut. Therefore it is important\
 to select the sRGB setting in 
the monitors OSD.
To do so, open the OSD by pressing the OK button on the front of your mo\
nitor. Move the down 
button to go to Color and press OK again. Use the right button to go to \
sRGB. Then move the down 
button and press OK again to exit the OSD.
After this, please do not change the brightness or contrast setting of y\
our monitor. If you change 
either of these, the monitor will exit the sRGB mode and go to a color t\
emperature setting of 6500K.

T
TFT(thin film transistor)
Usually made from amorphous silicon (a-Si) and used as a switch to a c\
harge storage device 
located below each sub-pixel on an active matrix LCD.
 
U 
 
USB or Universal Serial Bus
A smart plug for PC peripherals. USB automatically determines resources (like driver software and 
bus bandwidth) required by peripherals. USB makes necessary resources a\
vailable without user 
intervention.
l     USB eliminates case anxiety -- the fear of removing the computer case \
to install add-on 
peripherals. USB also eliminates adjustment of complicated IRQ settings \
when installing 
new peripherals. 
l     USB does away with port gridlock. Without USB, PCs are normally limite\
d to one printer, 
two Com port devices (usually a mouse and modem), one Enhanced Paralle\
l Port add-on 
(scanner or video camera, for example) and a joystick. More and more p\
eripherals for 
multimedia computers arrive on the market every day. With USB, up to 127\
 devices can run 
simultaneously on a computer. 
l     USB permits hot plug-in. Theres no need to shut down, plug in, reboot\
 and run set-up to 
install peripherals. And no need to go through the reverse process to un\
plug a device. 
In short, USB transforms todays Plug-and-Pray into true Plug-and-Play\
! 
Hub
 
A Universal Serial Bus device that provides additional connections to th\
e Universal Serial Bus. 
Hubs are a key element in the plug-and-play architecture of USB. The Fig\
ure shows a typical hub. 
Hubs serve to simplify USB connectivity from the users perspective prov\
iding low cost and 
complexity.
Hubs are wiring concentrators and enable the multiple attachment charact\
eristics of USB.

Glossary
Attachment points are referred to as ports. Each hub converts a single a\
ttachment point into 
multiple attachment points. The architecture supports concatenation of m\
ultiple hubs. 
The upstream port of a hub connects the hub towards the host. Each of th\
e other downstream ports 
of a hub allows connection to another hub or function. Hubs can detect, \
attach and detach at each 
downstream port and enable the distribution of power to downstream devic\
es. Each downstream 
port can be individually enabled and configured at either full or low sp\
eed. The hub isolates low 
speed ports from full speed signaling. 
A hub consists of two portions: the Hub Controller and Hub Repeater. The\
 repeater is a protocol-
controlled switch between the upstream port and downstream ports. It als\
o has hardware support 
for reset and suspend/resume signaling. The controller provides the inte\
rface registers to allow 
communication to/from the host. Hub specific status and control commands\
 permit the host to 
configure a hub and to monitor and control its ports. 
Device 
A logical or physical entity that performs a function. The actual entity\
 described depends on the 
context of the reference. At the lowest level, device may refer to a sin\
gle hardware component, as 
in a memory device. At a higher level, it may refer to a collection of h\
ardware components that 
perform a particular function, such as a Universal Serial Bus interface \
device. At an even higher 
level, device may refer to the function performed by an entity attached \
to the Universal Serial Bus; 
for example, a data/FAX modem device. Devices may be physical, electrica\
l, addressable, and 
logical.
 
 
 
 
Downstream 
The direction of data flow from the host or away from the host. A downst\
ream port is the port on a

hub electrically farthest from the host that generates downstream data t\
raffic from the hub. 
Downstream ports receive upstream data traffic. 
Upstream 
The direction of data flow towards the host. An upstream port is the por\
t on a device electrically 
closest to the host that generates upstream data traffic from the hub. U\
pstream ports receive 
downstream data traffic.
