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 to the Monitor.

Q: Will the LCD monitor accept an Interlace signal?

A: No If an Interlace signal is used, the screen displays both odd and even 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 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

(approximately up to the hardness of a 2H pencil). 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.
