numbness, or a burning or tingling sensation
aching, soreness or tenderness
pain, swelling or throbbing
stiffness or tightness
coldness or weakness

If you have these symptoms, or any other recurring or persistent discomfort and/
or pain related to computer use, consult a physician immediately and inform your company’s health and safety department.
The following section provides tips for more comfortable computer use.

refrain from staying too long in one fixed posture
avoid slouching forward and/or leaning backward
stand up and walk around regularly to remove the strain on your leg muscles

Taking care of your vision
Long viewing hours, wearing incorrect glasses or contact lenses, glare, excessive room lighting, poorly focused screens, very small typefaces and low- contrast displays could stress your eyes. The following sections provide suggestions on how to reduce eyestrain.

Eyes

Rest your eyes frequently.
Give your eyes regular breaks by looking away from the monitor and focusing on a istant point.
Blink frequently to keep your eyes from drying out.

Display

Adjust the display brightness and/or contrast to a comfortable level for enhanced text readability and graphics clarity.
Eliminate glare and reflections by:
- placing your display in such a way that the side faces the window or any light source
- minimizing room light by using drapes, shades or blinds
- 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.

Developing good work habits
Develop the following work habits to make your computer use more relaxing and productive:

Take short breaks regularly and often.

Connecting the cables

To install the monitor on your host system, please follow the steps below:

Turn off your computer and unplug your computer’s power cord.
Connect the signal cable to the DP (optional) and/or HDMI (optional) input socket of the monitor, and the DP (optional) and/or HDMI (optional) output socket of the graphics card on the computer.
Connect the USB Cable(Optional)
Connect the USB 3.0 cable to port for fast charge.
Connect the USB 3.0 cable to port.
USB 3.1 (Gen1) Type C-C cable (Optional, USB Type-C-C input models only) Connect one end of the USB 3.1(Gen1) Type C-C cable (optional) to your computer and connect the other end to your electric devices.
Insert the monitor power cable into the power port at the back of the monitor.
Connect the power adapter and power cord to the monitor, then to a properly grounded AC outlet.

Note: Audio output is only for audio output model. Please check user manual for more instruction.
AdaptiveSync :It can allow a AdaptiveSync supported graphics source to dynamically adjust display refresh rate based on typical content frame rates for power efficient, virtually stutter free and low-latency display update.

Connecting the adapter and AC 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 AC power cord to the Adapter, 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 driven into “Power Saving” mode by the control signal from the display controller, as indicated by amber -color power LED.

State	LED Light
ON	Amber
Power Saving Mode	Blinking amber

The power saving states will be kept until a control signal has been detected or the keyboard or mouse is activated. The recovery time from Active OFF state back to ON state 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.
