1. Safety and Installation

Safety precautions and maintenance

WARNING: Use of controls, adjustments or procedures other than those specified in this documentation may result in exposure to shock, electrical hazards and/or mechanical hazards.

Read and follow these instructions when connecting and using your monitor:

• Unplug the monitor if you are not going to use it for an extensive period of time.

• Unplug the monitor if you need to clean it with a slightly damp cloth. The screen many be wiped with a dry cloth when the power is off. However, never use alcohol, solvents or ammonia-based liquids.

• Consult a service technician if the monitor does not operate normally when you have followed the instructions in this manual.

• Only qualified service personnel should open the casing cover.

• Keep the monitor out of direct sunlight and away from stoves or any other heat source.

• Remove any object that could fall into the vents or prevent proper cooling of the monitor’s electronics.

• Do not block the ventilation holes on the cabinet.

• Keep the monitor dry. To avoid electric shock, do not expose it to rain or excessive moisture.

• If turning off the monitor by detaching power cable or DC power cord, wait for 6 seconds before reattaching the power cable or DC power cord for normal operation.

• To avoid the risk of shock or permanent damage to the monitor do not expose the monitor to rain or excessive moisture.

• When positioning the monitor, make sure the power plug and outlet are easily accessible.

• IMPORTANT: Always have a screen saver program installed on your computer. If a still image in high contrast remains on the screen for an extended period of time, it may leave an ‘after-image’ or ‘ghost image’ on the front of the screen. This is a well-known phenomenon that is caused by the shortcomings inherent in the LCD technology . In most cases the after-image will disappear gradually over a period of time after the power has been switched off. Be aware that the after-image symptom cannot be repaired and is not covered under warranty.

Consult a service technician if the monitor does not operate normally when the operating instructions given in this manual have been followed.

10. FAQ’s

General FAQ’s

Q: When I install my monitor what should I do if the screen shows ‘Cannot display this video mode’?

A: Recommended video mode is 1280x768 @60Hz.

1. Unplug all cables, then connect your PC to the monitor you used previously, which displayed correctly .

2. In the Windows Start Menu, select Settings/Control Panel. In the Control Panel Window, select the Display icon. Inside the Display Control Panel, select the ‘Settings’ tab. Under the settings tab, in a box labelled ‘desktop area’, move the slide bar to 1280x768 pixels.

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

4. Restart your computer and repeat steps 2 and 3 to verify that your PC is set at 1280x768@60Hz.

5. Shut down your computer , disconnect your old monitor and r econnect your Diamond Digital LCD monitor.

6. Turn on your monitor and then turn on your PC.

Q: How do I adjust the resolution?

A: Your video card/graphic driver and monitor together determine the available resolutions. You can select

the desired resolution under the Control Panel of Windows® 95/98, Me, 2000 or XP, and with the ‘Display properties/Settings’.

Q: What if I get lost while I am making monitor adjustments?

A: Simply press the MENU button, then select ‘Factory Reset/All Settings’ to recall all of the original factory

settings.

Q: My Monitor has no power (Power LED does not light up). What should I do?

A: Make sure the power cord is connected to the Monitor. Also, be sure the AC power switch at the rear of

the monitor is at ‘ON’ position.

Q: Will the product accept an Interlaced signal?

A: No. If an Interlaced 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 (up to 3H

in this Diamond Digital 30” LCD monitor). In general, it is recommended that the panel surface is not subjected to any excessive shocks or scratches.

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.

Self-Test Feature Check (STFC)

Your the LCD Monitor when used as a computer display through DVI and/or VGA connection provides a self-test feature that allows you to check whether your LCD Monitor TV is functioning properly. If your LCD Monitor and computer are properly connected but the LCD Monitor screen remains dark, run the LCD Monitor self-test by performing the following steps:

1. Turn off both your computer and the LCD Monitor.

2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital (white connector) and the Analogue (blue connector) cables from the back of computer.

3. Turn on the LCD Monitor.

The floating ‘Self-test Feature Check’ dialog box should appear on-screen (against a black background) if the LCD Monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.

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, calculators, portable game consoles, etc. LCD is the technology used for displays in notebooks and other small computers. Like light-emitting diode and gas-plasma technologies, LCD allows displays to be much thinner than cathode ray tube (CRT) technology. LCD consumes much less power than LED and gas-display displays because it works on the principle of blocking light rather than emitting it.

Q: How are LCDs made?

A: LCDs are created from two glass plates separated from each other at a distance of a few microns.

The plates are filled with liquid crystal and then sealed together. The top plate is coloured with an RGB pattern to make the colour filter. Polarizers are then glued to both plates. This combination is sometimes called ‘glass’ or ‘cell.’ The LCD cell is assembled into a ‘module’ by adding the backlight, driver electronics and frame.

Q: What is polarization?

A: Polarization is basically directing light to shine in one direction. Light is electromagnetic waves.

Electric and magnetic fields oscillate in a direction perpendicular to the propagation of the light beam. The direction of these fields is called the ‘polarization direction’. Normal or non-polarized light has fields in several directions; polarized light has a field in only one direction.

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, requiring 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 located at each intersection in the grid.

Q: How does a TFT LCD Panel work?

A: On each column and row of the TFT LCD panel a data source drive and a gate drive are attached

respectively. The TFT drain of each cell is connected to the electrode. The molecular arrangement of liquid crystal elements differs acceding to whether it is impressed with voltage or not. It varies the direction of polarized light and the amount of light by letting it through different arrays of liquid crystal elements. When two polarized filters are arranged vertically on a polarized light pole, the light that passes through the upper polarized panel is turned 90 degrees along with the spiral structure of the liquid crystal molecules and goes through the polarized filter at the bottom. When impressed with voltage, liquid crystal molecules are arranged vertically from the original spiral structure and the direction of the light is not turned through 90 degrees. In this case, light that comes through the top polarized panel may not go through the polarized panel at the bottom.

Q: Can the Diamond Digital LCD Monitor be mounted on the wall or used as a touch panel?

A: Yes, Diamond Digital LCD monitors have this optional feature. The standard VESA mount holes on the

back cover allow the user to mount the Diamond Digital monitor on any VESA standard ARM or accessories. Touch panels are being developed for future applications. Check with your Diamond Digital sales representative for more information.

Screen Adjustments

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 1280x768@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.

Compatibility with other Peripherals

Q: Can I connect my LCD monitor to any PC, workstation or Mac?

A: Yes, all Diamond Digital LCD monitors are fully compatible with standard PCs, Macs and workstations.

You may need a cable adapter to connect the monitor to your Mac system. Please contact your dealer/retailer for more information.

Q: Are Diamond Digital LCD monitors Plug-and-Play?

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

Q: What is a TV System?

A: Television pictures are not broadcast in the same way in all countries. There are different standards: BG,

DK, I and L L’. The SYSTEM setting is used to select these different standards. This is not to be confused with PAL or SECAM colour coding. PAL is used in Australia and the majority of European countries, Secam in France, the CIS and the majority of African countries. The United States and Japan use a different system called NTSC.

Q: What is SCART?

A: The SCART is a 20-pin rectangular connector fitted to the vast majority of PAL market TV receivers. It

provides composite video inputs and outputs, stereo audio in and out, and RGB input. It is also known as Euro connector and PERI-tel.

Q: What are S-VIDEO Signals?

A: These are 2 separate Y/C video signals from the S-VIDEO and Hi-8 recording standards. The luminance

signals Y (black and white) and chrominance signals C (colour) are recorded separately on the tape. This provides a better picture quality than is achieved with standard video (VHS and 8mm) where the Y/C signals are combined to provide only one video signal.

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 operate with an analogue 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 elements. A TFT LCD has two glass panels and the space between them is filled in with liquid crystal. When each cell is connected with electrodes and impressed with voltage, the molecular structure of the liquid crystal is altered and controls the amount 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 scanning method.

Q: Why is a vertical frequency of 60Hz optimal for an LCD monitor?

A: Unlike a CRT monitor, the TFT LCD panel has a fixed resolution. For example, 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 optimise 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 optimum 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 backlight using the dual refraction

of a liquid crystal. Using the property that the projection of inlet light refracts toward the major axis of the liquid element, it controls the direction of inlet light and displays it. Since the refraction ratio of inlet light on liquid crystal 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 ratio is 10. Many ways to widen the viewing angle are currently being developed and the most common approach is to use a wide viewing angle film, which widens 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 CRT

monitor — and it has no impact of the ease of viewing. Flickering in an LCD monitor relates to usually undetectable luminance caused 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 fluorescent object becomes visible. Since the reaction speed of liquid crystal in an LCD panel is much slower, this troublesome form of flickering is not present in an LCD display.

Q: Why is an LCD monitor virtually free of Electro Magnetic Interference?

A: Unlike a CRT, an LCD monitor does not have key parts that generate Electro Magnetic Interference,

especially magnetic fields. Also, since an LCD display utilizes relatively low power, its power supply is extremely quiet.

sRGB

sRGB is a standard for ensuring correct exchange of colours between different devices (e.g. digital cameras, monitors, printers, projectors, scanners, etc.).

Using a standard unified color space, sRGB will help represent pictures taken by an sRGB compatible device correctly on your sRGB enabled Diamond Digital monitor. In that way, the colours are calibrated and you can rely on the correctness of the colours shown on your screen.

Important with the use of sRGB is that the brightness and contrast of your monitor is fixed to a predefined setting as well as the colour gamut. Therefore it is important to select the sRGB setting in the monitor’s OSD.

To do so, at PC mode, open the OSD by pressing the MENU button of your monitor. Use the down button to go to COLOR SETTINGS and press MENU again. Then move the down button to go to NORMAL COLOR and press MENU again.

For more information on sRGB, please visit: www.srgb.com
