Frequently Asked Questions - AT1931 ACER

How do I connect my computer to the Acer AT1931?

Power off your computer. Connect the VGA or DVI cable from the monitor to your PC. For audio, connect the 3.5mm stereo cable from your PC's line-out to the monitor's line-in. Then connect the AC adapter and power on.

What video sources can I use with this monitor?

The AT1931 supports VGA (analog RGB), DVI-D (digital), composite video (RCA yellow), and S-Video. It can display standard definition TV signals from devices like DVD players or gaming consoles.

How do I adjust the viewing angle?

Gently tilt the monitor forward or backward within a range of -5° to +25°. Do not force beyond these limits to avoid damage.

How do I use the on-screen display (OSD) menu?

Press the Menu button on the front bezel to open the OSD. Use the left/right Function Select buttons to navigate, and the up/down Adjustment buttons to change settings. Press Menu again to enter a submenu or confirm.

My screen shows 'No Input Signal' or 'Out of Range'. What should I do?

Ensure the correct input source is selected and the cable is securely connected. 'Out of Range' means the signal timing is not supported; use a standard resolution like 1280x1024 at 60Hz. If no signal, try pressing the Auto button or cycling power.

How do I clean the LCD screen without damaging it?

Power off and unplug the monitor. Spray a non-solvent cleaner (like water or mild soap) onto a soft, lint-free cloth, not directly on the screen. Gently wipe the screen in a circular motion.

What are the power saving modes?

The monitor supports VESA DPMS. When no sync signal is detected, it enters standby, suspend, or off mode, reducing power to under 5W. The LED turns yellow in power saving mode.

Can I mount this monitor on a wall or arm?

Yes, the monitor has a VESA 100x100 mm mount on the rear. Use four M4 x 8mm screws (not included). Remove the stand by unscrewing it from the bracket.

Why is the picture blurry or flickering?

Go to the OSD and adjust the 'Clock' and 'Phase' settings under the 'Picture' menu. First adjust Clock until vertical stripes disappear, then Phase for sharpness. Also ensure the resolution is set to the native 1280x1024.

How do I reset the monitor to factory settings?

In the OSD menu, select 'Reset' then 'Memory recall'. This will revert all settings to factory defaults. You must be using a factory preset video mode for this to work.

Chapter 1 Installation

Unpacking

Before unpacking the LCD Monitor, prepare a suitable workspace for your Monitor and computer. You need a stable and clean surface near a wall power outlet. Make sure that LCD Monitor has enough space around it for sufficient airflow. Though the LCD Monitor uses very little power, some ventilation is needed to ensure that the Monitor does not become too hot.

After you unpack the LCD Monitor, make sure that the following items were included in the box:

* LCD Monitor * User's Manual

* 1.8M Monitor-to-PC VGA Cable * AC Adapter

* 1.8M Monitor-to-PC DVI-D Cable * 1.8M Power Cord

Troubleshooting

This LCD Monitor has pre-adjusted using factory standard VGA timings. Due to the output timing differences among various VGA cards in the market, users may initially experience an unstable or unclear display whenever a new display mode or new VGA card is selected.

Attention

This LCD Monitor Supports Multiple VGA Modes.

Refer to the Standard Timing Table for a listing of modes supported by this LCD Monitor.

PROBLEM Picture is unclear and unstable

The picture is unclear and unstable, please perform the following steps:

1. Enter PC to "Shut Down Windows" status while you're in MS-Windows environment.
2. Check the screen to see if there's any black vertical stripes appear. If there are, take advantage of the "Clock" function in OSD menu and adjust (by increment or decrement numbers) until those bars disappear.
3. Move to "Phase" function in OSD menu again and adjust the monitor screen to its most clear display.
4. Click "No" on "Shut Down Windows" and back to the normal PC operating environment.

PROBLEM There is no picture on LCD Monitor

If there's no picture on the LCD Monitor, please perform the following steps:

1. Make sure the power indicator on the LCD Monitor is ON, all connections are secured, and the system is running on the correct timing. Refer to Chapter 3 for information on timing.
2. Turn off the LCD Monitor and then turn it back on again. If there is still no picture, press the Adjustment Control button several times.
3. If step 2 doesn't work, connect your PC system to another external CRT. If your PC system Functions properly with a CRT Monitor but it does not function with the LCD Monitor, the output timing of the VGA card may be out of the LCD's synchronous range. Please change to an alternative mode listed in the Standard Timing Table or replace the VGA card, and then repeat steps 1 and 2.

PROBLEM There is no picture on LCD Monitor

If you have chosen an output timing that is outside of the LCD Monitor's synchronous range (Horizontal: 30 \~ 80 KHz and Vertical: 56 \~ 75 Hz), the OSD will display a "Out of Range" message. Choose a mode that is supported by your LCD Monitor.

Also, if the signal cable is not connected to LCD monitor at all or properly, the monitor screen will display a message "No Input Signal".
