FAQs (Frequently Asked Questions)
General FAQs 
Q:
 When I install my monitor what should I do if the screen shows Cannot \
display this video 
mode?
A:
Recommended video mode for Philips 24: 1920x1200 @60Hz.


Unplug all cables, then connect your PC to the monitor that you used 
previously.


In the Windows Start Menu, select Settings/Control Panel. In the Control\
 Panel 
Window, select the Display icon. Inside the Display Control Panel, selec\
t the 
Settings tab. Under the setting tab, in box labeled desktop area, mo\
ve the 
slidebar to 1920x1200 pixels (24).


Open Advanced Properties and set the Refresh Rate to 60Hz, then click \
OK.


Restart your computer and repeat step 2 and 3 to verify that your PC is \
set at 
1920x1200@60Hz (24).


Shut down your computer, disconnect your old monitor and reconnect your \
Philips LCD monitor.


Turn on your monitor and then turn on your PC.
Q: What are the .inf and .icm files on the CD-ROM? How do I install the dr\
ivers (.inf and .
icm)?
A:
These are the driver files for your monitor. Follow the instructions in \
your user 
manual to install the drivers. Your computer may ask you for monitor dri\
vers (.inf and .
icm files) or a driver disk when you first install your monitor. Follow\
 the instructions to 
insert the (companion CD-ROM) included in this package. Monitor driver\
s (.inf and .
icm files) will be installed automatically.
Q: How do I adjust the resolution?
A:
Your video card/graphic driver and monitor together determine the availa\
ble 
resolutions. You can select the desired resolution under Windows® Con\
trol Panel 
with the Display properties
.

Q: What if I get lost when I am making monitor adjustments?
A: Simply press the MENU button, the Setup button, then select Reset to \
recall all of 
the original factory settings.
Q: What is the Auto function?
A:
The AUTO adjustment key restores the optimal screen position, phase and clock 
settings by pressing of a single button – without the need to navigate through OSD 
(On Screen Display) menus and control keys. 
 
Note: Auto function is available in selected models only.
Q: My Monitor has no power (Power LED does not light up). What should I \
do?
A: Make sure the AC power cord is connected between the monitor and AC out\
let, 
and click a key on keyboard/mouse to wake up the PC. 
Q: Will the LCD monitor accept an interlaced signal under PC models?
A: No. If an Interlace signal is used, the screen displays both odd and ev\
en horizontal 
scanning lines at the same time, thus distorting the picture.
Q:
What does the Refresh Rate mean for LCD?
A: Unlike CRT display technology, in which the speed of the electron beam \
is swept 
from the top to the bottom of the screen determines flicker, an active m\
atrix display 
uses an active element (TFT) to control each individual pixel and the \
refresh rate is 
therefore not really applicable to LCD technology. 




Q: Will the LCD screen be resistant to scratches?
 
						

							2T
	SFRVFOUMZ
TLFE
2VFTUJPOT

A:
A protective coating is applied to the surface of the LCD, which is dura\
ble to a 
certain extent (approximately up to the hardness of a 2H pencil). In g\
eneral, it is 
recommended that the panel surface is not subject to any excessive shock\
s or 
scratches.


Q: How should I clean the LCD surface?
A: For normal cleaning, use a clean, soft cloth. For extensive cleaning, p\
lease use 
isopropyl alcohol. Do not use other solvents such as ethyl alcohol, etha\
nol, acetone, 
hexane, etc.


Q:Can I change the color setting of my monitor?
A:Yes, you can change your color setting through OSD control as the follow\
ing 
procedures,
1. Press MENU to show the OSD (On Screen Display) menu


2. Press Down Arrow to select the option Color then press OK to en\
ter color 
setting, there are three settings as below.
a. Color Temperature; The six settings are  5000K, 6500K, 7500K, 
8200K, 9300K and 11500K. With settings in the 5000K range the panel 
appears ‘warm, with a red-white color tone, while a 11500K 
temperature yields ‘cool, blue-white toning.
 
b. sRGB; this is a standard setting for ensuring correct exchange of 
colors between different device (e.g. digital cameras, monitors, printe\
rs, 
scanners, etc)
 
c. User Define; the user can choose his/her preference color setting by \
adjusting red, green blue color.
 
d. Gamma; The five settings are 1.8, 2.0, 2.2, 2.4, and 2.6. 
*A measurement of the color of light radiated by an object while it is b\
eing heated. 
This measurement is expressed in terms of absolute scale, (degrees Kelv\
in). Lower 
Kevin temperatures such as 2004K are red; higher temperatures such as 93\
00K are 
blue. Neutral temperature is white, at 6504K.

onitor?
A:For best performance, make sure your display settings are set at 
1920x1200@60Hz for 24.  


Q: How do LCDs compare to CRTs in terms of radiation?
A: Because LCDs do not use an electron gun, they do not generate the same \
amount 
of radiation at the screen surface.

Compatibility with other Peripherals
Q:
 Can I connect my LCD monitor to any PC, workstation or Mac?
A: Yes. All Philips LCD monitors are fully compatible with standard PCs, M\
acs and 
workstations. You may need a cable adapter to connect the monitor to you\
r Mac 
system. Please contact your Philips sales representative for more inform\
ation.

A: Yes, the monitors are Plug-and-Play compatible with Windows® 95, 98,\
 2000, XP 
and Vista.


Q: What is USB (Universal Serial Bus)?
A: Think of USB as a smart plug for PC peripherals. USB automatically dete\
rmines 
resources (like driver software and bus bandwidth) required by periphe\
rals. USB 
makes necessary resources available without user intervention. There are\
 three main 
benefits of USB. USB eliminates case anxiety, the fear of removing the\
 computer 
case to install circuit board cards -- that often requires adjustment of\
 complicated IRQ 
settings -- for add-on peripherals. USB does away with port gridlock. \
Without USB, 
PCs are normally limited to one printer, two Com port devices (usually \
a mouse and 
modem), one Enhanced Parallel Port add-on (scanner or video camera, fo\
r example), 
and a joystick. More and more peripherals for multimedia computers come \
on the 
market every day. With USB, up to 127 devices can run simultaneously on \
one 
computer. USB permits hot plug-in. No need to shut down, plug in, rebo\
ot and run 
set up to install peripherals. No need to go through the reverse process\
 to unplug a 
device. Bottom line: USB transforms todays Plug-and-Pray into true Pl\
ug-and-Play! 
 
Please refer to glossary for more information about USB.


Q: What is a USB hub ? 
A: A USB hub provides additional connections to the Universal Serial Bus. \
A hubs 
upstream port connects a hub to the host, usually a PC. Multiple downstr\
eam ports in 
a hub allows connection to another hub or device, such as a USB keyboard\
, camera 
or printer.

LCD Panel Technology
Q:
 What is a Liquid Crystal Display?
A: A Liquid Crystal Display (LCD) is an optical device that is commonly \
used to 
display ASCII characters and images on digital items such as watches, ca\
lculators, 
portable game consoles, etc. LCD is the technology used for displays in \
notebooks 
and other small computers. Like light-emitting diode and gas-plasma tech\
nologies, 
LCD allows displays to be much thinner than cathode ray tube (CRT) tec\
hnology. 
LCD consumes much less power than LED and gas-displays because it works \
on the

principle of blocking light rather than emitting it.



Q:
 What differentiates passive matrix LCDs from active matrix LCDs?
A: An LCD is made with either a passive matrix or an active matrix display\
 grid. An 
active matrix has a transistor located at each pixel intersection, requi\
ring less current 
to control the luminance of a pixel. For this reason, the current in an \
active matrix 
display can be switched on and off more frequently, improving the screen\
 refresh time 
(your mouse pointer will appear to move more smoothly across the screen\
, for 
example). The passive matrix LCD has a grid of conductors with pixels l\
ocated at 
each intersection in the grid.


Q: What are the advantages of TFT LCD compared with CRT?
A: In a CRT monitor, a gun shoots electrons and general light by colliding\
 polarized 
electrons on fluorescent glass. Therefore, CRT monitors basically operat\
e with an 
analog RGB signal. A TFT LCD monitor is a device that displays an input \
image by 
operating a liquid crystal panel. The TFT has a fundamentally different \
structure than 
a CRT: Each cell has an active matrix structure and independent active e\
lements. A 
TFT LCD has two glass panels and the space between them is filled with l\
iquid 
crystal. When each cell is connected with electrodes and impressed with \
voltage, the 
molecular structure of the liquid crystal is altered and controls the am\
ount of inlet 
lighting to display images. A TFT LCD has several advantages over a CRT,\
 since it 
can be very thin and no flickering occurs because it does not use the sc\
anning 
method.


Q: Why is vertical frequency of 60Hz optimal for an LCD monitor?
A: Unlike a CRT monitor, the TFT LCD panel has a fixed resolution. For exa\
mple, an 
XGA monitor has 1024x3 (R, G, B) x 768 pixels and a higher resolution \
may not be 
available without additional software processing. The panel is designed \
to optimize 
the display for a 65MHz dot clock, one of the standards for XGA displays\
. Since the 
vertical/horizontal frequency for this dot clock is 60Hz/48kHz, the opti\
mum frequency 
for this monitor is 60Hz.


Q: What kind of wide-angle technology is available? How does it work?
A: The TFT LCD panel is an element that controls/displays the inlet of a b\
acklight 
using the dual-refraction of a liquid crystal. Using the property that t\
he projection of 
inlet light refracts toward the major axis of the liquid element, it con\
trols the direction 
of inlet light and displays it. Since the refraction ratio of inlet ligh\
t on liquid crystal 
 
						

							2T
	SFRVFOUMZ
TLFE
2VFTUJPOT

varies with the inlet angle of the light, the viewing angle of a TFT is \
much narrower 
than that of a CRT. Usually, the viewing angle refers to the point where\
 the contrast 
ration is 10. Many ways to widen the viewing angle are currently being d\
eveloped and 
the most common approach is to use a wide viewing angle film, which wide\
ns the 
viewing angle by varying the refraction ratio. IPS (In Plane Switching)\
 or MVA (Multi 
Vertical Aligned) is also used to give a wider viewing angle. 
Q: Why is there no flicker on an LCD Monitor?
A: Technically speaking, LCDs do flicker, but the cause of the phenomenon \
is 
different from that of a CRT monitor -- and it has no impact of the ease\
 of viewing. 
Flickering in an LCD monitor relates to usually undetectable luminance c\
aused by the 
difference between positive and negative voltage. On the other hand, CRT\
 flickering 
that can irritate the human eye occurs when the on/off action of the flu\
orescent object 
becomes visible. Since the reaction speed of liquid crystal in an LCD pa\
nel is much 
slower, this troublesome form of flickering is not present in an LCD dis\
play.


Q: Why is an LCD monitor virtually low of Electro Magnetic Interference?
A: Unlike a CRT, an LCD monitor does not have key parts that generate Elec\
tro 
Magnetic Interference, especially magnetic fields. Also, since an LCD di\
splay utilizes 
relatively low power, its power supply is extremely quiet.

Ergonomics, Ecology and Safety Standards
Q:
 What is the CE mark?
A: The CE (Conformité Européenne) mark is required to be displayed\
 on all regulated 
products offered for sale on the European market. This CE mark means t\
hat a 
product complies with the relevant European Directive. A European Direct\
ive is a 
European Law that relates to health, safety, environment and consumer \
protection, 
much the same as the U.S. National Electrical Code and UL Standards.


Q: Does the LCD monitor conform to general safety standards?
