Frequently Asked Questions - S2820HSB-B1 IIYAMA

What should I do if the screen shows no picture?

First, ensure the power cable is firmly connected and the monitor is turned on. Check if the computer is on and the signal cable is properly attached. The power indicator should be green; if red, the monitor may be in power management mode—touch the keyboard or mouse. Also, verify that the signal timing is within the monitor's specifications.

How do I clean the LCD screen?

Turn off the monitor and unplug it. Use a soft, dry cloth to gently wipe the screen. Do not use tissue paper, as it may scratch the surface. Avoid any strong solvents like thinner, benzene, or abrasive cleaners.

What is image persistence and how can I prevent it?

Image persistence (or 'ghost' image) occurs when a static image is displayed for a long time. To prevent it, avoid displaying static images for extended periods, use a screen saver, or turn off the monitor when not in use. If ghosting appears, turn off the monitor for as long as the image was displayed to clear it.

Can I mount this monitor on a wall?

Yes, it supports VESA mounting standards: 400 × 75 mm and 75 × 75 mm. Use M4 or M6 screws with washers, ensuring the screw length is 5 mm to avoid damaging internal components. The wall must be strong enough to hold the monitor's weight (5.4 kg).

What is the maximum supported resolution?

The maximum resolution is 1920 × 360 (0.7 megapixels). The monitor also supports standard timings like 1920 × 1080 at 60 Hz. For best picture quality, use the native resolution.

Why is there no sound from the built-in speakers?

Ensure the audio source (computer) is turned on and the audio cable is securely connected to the monitor's Audio In jack. Check that the volume is not muted (use the OSD menu) and the audio output level is appropriate (0.5 Vrms max).

How do I adjust the screen position if it's not centered?

Press the MENU button, navigate to the 'Image' menu (for VGA input) or use 'Auto Adjustment' first. Use the arrow buttons to adjust H. Position and V. Position manually. If the issue persists, ensure the computer's signal timing matches the monitor's supported timings.

What is the power consumption of this monitor?

Typical power consumption is 28 W. The monitor is Energy Efficiency Class C. It uses a 12 VDC, 5.0 A power supply via the included AC adapter (input: 100-240 VAC, 50/60 Hz).

Is this monitor suitable for 24/7 operation?

Yes, it is designed for 24 hours per day usage under moving picture conditions. For static images, use screen savers and adjust brightness to minimize image persistence. Ensure adequate ventilation and consider using the cooling fan if available.

How do I reset the monitor to factory settings?

Press the MENU button to open the On-Screen Display. Navigate to the 'Tools' menu and select 'Reset'. This restores all factory-preset data. Confirm by pressing the MENU button again.

NEVER REMOVE THE CABINET

High voltage circuits are inside the monitor. Removing the cabinet may expose you to the danger of fire or electric shock.

DO NOT PUT ANY OBJECT INTO THE MONITOR

Do not put any solid objects or liquids such as water into the monitor. In case of an accident, unplug your monitor immediately and contact your dealer or iiyama service center. Using the monitor with any object inside may cause fire, electric shock or damage.

INSTALL THE MONITOR ON A FLAT, STABLE SURFACE

The monitor may cause an injury if it falls or is dropped.

DO NOT USE THE MONITOR NEAR WATER

Do not use where water may be splashed or spilt onto the monitor as it may cause fire or electric shock.

OPERATE UNDER THE SPECIFIED POWER SUPPLY

Be sure to operate the monitor only with the specified power supply. Use of an incorrect voltage will cause malfunction and may cause fire or electric shock.

PROTECT THE CABLES

Do not pull or bend the power cable and signal cable. Do not place the monitor or any other heavy objects on the cables. If damaged, the cables may cause fire or electric shock.

ADVERSE WEATHER CONDITIONS

It is advisable not to operate the monitor during a heavy thunder storm as the continual breaks in power may cause malfunction. It is also advised not to touch the plug in these circumstances as it may cause electric shock.

CAUTION

INSTALLATION LOCATION

Do not install the monitor where sudden temperature changes may occur, or in humid, dusty or smoky areas as it may cause fire, electric shock or damage. You should also avoid areas where the sun shines directly on the monitor.

DO NOT PLACE THE MONITOR IN A HAZARDOUS POSITION

The monitor may topple and cause injury if not suitably located. Please also ensure that you do not place any heavy objects on the monitor, and that all cables are routed such that children may not pull the cables and possibly cause injury.

MAINTAIN GOOD VENTILATION

Ventilation slots are provided to keep the monitor from overheating. Covering the slots may cause fire. To allow adequate air circulation, place the monitor at least 10 cm (or 4 inches) from any walls. Operating the monitor on its back, side, upside down or on a carpet or any other soft material may also cause damage.

DISCONNECT THE CABLES WHEN YOU MOVE THE MONITOR

When you move the monitor, turn off the power switch, unplug the monitor and be sure cable is disconnected. If you do not disconnect them, it may cause fire or electric shock.

UNPLUG THE MONITOR

If the monitor is not in use for a long period of time it is recommended that it is left unplugged to avoid accidents.

OTHERS

ERGONOMIC RECOMMENDATIONS

To eliminate eye fatigue, do not operate the monitor against a bright background or in a dark room. For optimal viewing comfort, the monitor should be just below eye level and 40-60 cm (16-24 inches) away from your eyes. When using the monitor over a prolonged time, a ten minute break every hour is recommended as looking at the screen continuously can cause eye strain.

SPECIAL NOTES ON LCD MONITORS

■ The following symptoms are normal with LCD monitors and do not indicate a problem.

NOTE

• When you first turn on the LCD monitor, the picture may not fit in the display area because of the type of computer that is used. In this case, adjust the picture position to the correct position.
• You may find slightly uneven brightness on the screen depending on the desktop pattern you use.
• Due to the nature of the LCD screen, an afterimage of the previous screen may remain after switching the image, when the same image is displayed for hours. In this case, the screen is recovered slowly by changing the image or turning off the Power Switch for hours.

■ This LCD cannot be used outdoors.
■ This LCD cannot be used with the screen facing upwards.
■ If you use a cable longer than the supplied one, the picture quality is not guaranteed.

USAGE CONFIRMATION

This product is designed for optimum usage at 24 hours per day.

The display is compatible for usage in Landscape/Portrait applications.

IMAGE PERSISTENCE / IMAGE STICKING

Please be aware that all LCD screens can experience Image Persistence or Image Sticking. This occurs when a residual image remains visible on a screen when static images are displayed for long periods of time. LCD Image Persistence is not permanent but constant images being displayed for a long period of time should be avoided.

To counteract Image Persistence, turn off the monitor for as long as the previous image was displayed, so if an image was on the monitor for 1 hour and there is evidence of a residual or “ghost” image, you should turn off the monitor for 1 hour in order to clear the residual image.

For all LFD products, iiyama recommends displaying moving images and utilising a moving screen saver at regular intervals whenever the screen is idle. You could also turn off the monitor when not in use to assist the prevention.

Other ways to reduce the risk of Image Persistence will be to utilise the FAN-on function (if available), Low Backlight and Low Brightness settings.

FOR EXTENDED USE AS A PUBLIC DISPLAY

■ Image Sticking on LCD Panel

When a static image is displayed for hours, an electric charge trace remains near the electrode inside the LCD producing a “ghost” image. (Image Persistence).

Image Persistence is not a permanent feature.

■ Recommendations

To prevent Image Sticking and promote longer life expectancy of display, we recommend the following:

1. Avoid static images displayed for long periods – change static images on continuous loop.
2. Turn off monitor when not in use, either by remote control or use Power Management or Schedule functions.
3. When monitor is installed in high ambient temperature environment(s) or in an enclosed position, utilise the Cooling Fan, Screen Saver and Low Brightness functions.
4. Suitable ventilation for any monitor is an expectation of any installation – climate control systems may need to be employed.
5. We strongly recommend utilisation of active cooling with fans for long operation times or high ambient temperature environments.

SCREEN ADJUSTMENTS

Adjust the image by following the procedure below to get the desired picture when selecting Analog input.

■ The screen adjustments described in this manual are designed to set image position and minimize flicker or blur for the particular computer in use.
■ The monitor is designed to provide the best performance at resolution of 1920 × 1080 , but can not provide the best at resolutions of less than 1920 × 1080 because the picture is automatically stretched to fit the full screen. It is recommended to operate at resolution of 1920 × 1080 in normal use.
■ Displayed text or lines will be blurred or irregular in thickness when the picture is stretched due to the screen enlargement process.
■ It is preferable to adjust the image position and frequency with the monitor controls, rather than the computer software or utilities.
■ Perform adjustments after a warm-up period of at least thirty minutes.
■ Additional adjustments may be required after the Auto Adjust depending on the resolution or signal timing.
■ The Auto Adjust may not work correctly when displaying the picture other than the screen adjustment pattern. In this case, manual adjustments are required.

There are two ways to adjust the screen. One way is automatic adjustment for Position, Clock and Phase. The other way is performing each adjustment manually.

Perform the Auto Adjust first when the monitor is connected to a new computer, or resolution is changed. If the screen has a flicker or blur, or the picture does not fit in the display area after performing the Auto Adjust, manual adjustments are required. Both adjustments should be made by using the screen adjustment pattern (Test.bmp) obtained via the IIYAMA web site (http://www.iiyama.com).

Adjust the image by following the procedure below to get the desired picture.

This manual explains adjustment under Windows ^® OS.

① Display the picture at the optimum resolution.
② Enter the Test.bmp (screen adjustment pattern) to wallpaper.
① Display the picture at the optimum resolution.
② Enter the Test.bmp (screen adjustment pattern) to wallpaper.

NOTE

■ Consult the appropriate documentation for doing this.
■ Set the display position to center in the wallpaper setting dialogue box. If you use Microsoft® PLUS! 95/98 cancel the setting of “Stretch desktop wallpaper screen”.

[Adjustment pattern]

③ Adjust the Auto Adjustment.
④ Adjust the image manually by following procedure below when the screen has a flicker or blur, or the picture does not fit in the display area after performing the Auto Adjust.
⑤ Adjust the V. Position so that the top and bottom of the picture frame will fit to the display area.

NOTE

■ When the left side of the picture frame moves apart from the left edge of the display area during the Clock adjustment, adjust steps 1) and 2).
■ Another way to make the Clock adjustment is to correct the vertical wavy lines in the zebra pattern.
■ The picture may flicker during the Clock, H./V. Position adjustment.
In case the picture frame is bigger or smaller than the data display area after the Clock adjustment, repeat steps from ③.

⑦ Adjust the Phase to correct horizontal wavy noise, flicker or blur in the zebra pattern.

NOTE

In case the strong flicker or blurs remain on a part of the screen, repeat steps ⑥ and ⑦ because the Clock may not be adjusted correctly. If the flicker or blurs still remain, set the refresh rate of computer to low (60Hz) and repeat steps from ③ again.
■ Adjust the H. Position after the Phase adjustment if the horizontal position moves during the adjustment.

⑧ Adjust the Brightness and Color to get the desired picture after you complete the Clock and Phase adjustments.
