Acer K202HQL, K242HQL Manual

Unpacking

Please check that the following items are present when you unpack the box, and save the packing materials in case you need to ship or transport the monitor in the future.

Attaching the Base

Note: Remove the monitor and monitor base from its packaging. Carefully place the monitor face-down on a stable surface - use a cloth to avoid scratching the screen.
Attaching the Base
Remove: Reverse the steps to remove the base.

Screen position adjustment

To optimize the viewing position, you can adjust the monitor tilt by using both of your hands to hold the edges of the monitor as shown below.
The monitor can be adjusted to 25 degrees up or 5 degrees down.

Connecting the power cord

Check first to make sure that the power cord you use is the correct type required for your area.
The monitor has a universal power supply that allows operation in either 100/120 V AC or 220/240 V AC voltage area. No user-adjustment is required.
Plug one end of the power cord to the AC inlet, and plug the other end into an AC outlet.
For units using 120 V AC:
Use a UL-listed cord set, type SVT wire and plug rated 10 A/125 V.
For units using 220/240 V AC:
Use a cord set consisting of H05VV-F cord and plug rated 10 A/250 V. The cord set should have the appropriate safety approvals for the country in which the equipment will be installed.

Power saving

The monitor will be switched to "power saving" mode by the control signal from the display controller, as indicated by the amber-colored power LED.

Mode	LED light
On	Blue
Power saving	Amber

The power saving mode will be kept until a control signal has been detected or the keyboard or mouse is activated. The recovery time from "power saving" mode back to "on" is around 3 seconds.

Display Data Channel (DDC)

To make installation easier, so long as your system supports the DDC protocol, the monitor is able to plug-and-play. The DDC is a communication protocol through which the monitor automatically informs the host system about its capabilities; for example, supported resolutions and corresponding timing. The monitor supports the DDC2B standard.

Special notes on LCD monitors

The following are normal with the LCD monitor and do not indicate a problem.

Due to the nature of the fluorescent light, the screen may flicker during initial use. Turn off the power switch and then turn it on again to make sure the flicker disappears.
You may find slightly uneven brightness on the screen depending on the desktop pattern you use.
The LCD screen has 99.99% or more effective pixels. It may include blemishes of 0.01% or less such as a missing pixel or a pixel lit all the time.
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 a few hours.

- using a task light
- changing the display's viewing angle
- using a glare-reduction filter
- using a display visor, such as a piece of cardboard extended from the display's top front edge
Avoid adjusting your display to an awkward viewing angle.
Avoid looking at bright light sources, such as open windows, for extended periods of time.
