Q: What does the Refresh Rate mean for LCD?
A: Unlike CRT display technology, in which the speed at which the electron beam is swept from
the top to the bottom of the screen determines flicker, an active matrix 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?
A: A protective coating is applied to the surface of the LCD, which is durable to a certain extent
(up to 3H in this Philips 42" LCD monitor). In general, it is recommended that the panel surface is
not subjected to any excessive shocks or scratches. An optional protective cover with greater
scratch resistance is also available.
Q: How should I clean the LCD surface?
A: For normal cleaning, use a clean, soft cloth. For extensive cleaning, please use isopropyl alcohol.
Do not use other solvents such as ethyl alcohol, ethanol, acetone, hexane, etc.
Q: Can the Philips LCD Monitor be mounted on the wall or used as a touch panel?
A: Yes, Philips LCD Monitors have this optional feature. The standard VESA mount holes on the
back cover allow the user to mount the Philips monitor on any VESA standard ARM or
accessories. Check with your Philips sales representative for more information.

Q: When I install my monitor, how do I get the best performance from the monitor?
A: For best performance, make sure your display settings are set at 1366x768@60Hz.
Note: You can check the current display settings by pressing the OSD OK button once.
The current display mode is shown in the product information in the OSD main controls.
Q: How do LCDs compare with CRTs in terms of radiation?
A: Unlike CRT, the LCDs do not use an electron gun, so they do not generate the same amount of
radiation at the screen surface.
