Chapter 2. Adjusting and using your monitor

This section will give you information on adjusting and using your monitor.
Comfort and accessibility
Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort. Arrange your workplace and the equipment you use to suit your individual needs and the kind of work that you perform. In addition, use healthy work habits to maximize your performance and comfort while using your computer.
Arranging your work area
Use a work surface of appropriate height and available working area to allow you to work in comfort.
Organize your work area to match the way you use materials and equipment. Keep your work area clean and clear for the materials that you typically use and place the items that
you use most frequently, such as the computer mouse or telephone, within the easiest reach. Equipment layout and setup play a large role in your working posture. The following topics describe how to optimize equipment set up to achieve and maintain a good working posture.
Positioning and viewing your monitor
Position and adjust your computer monitor for comfortable viewing by considering the following items:

• Viewing distance: Optimal viewing distances for monitors range from approximately 510mm to 760mm (20 into 30 in) and can vary depending on ambient light and time of day. You can achieve different viewing distances by repositioning your monitor or by modifying your posture or chair position. Use a viewing distance that is most comfortable
  for you.

• Monitor height: Position the monitor so your head and neck are in a comfortable and neutral (vertical, or upright) position. If your monitor does not have height adjustments, you might have to place books or other sturdy objects under the base of the monitor to achieve the desired height. A general guideline is to position the monitor such that the top of the screen is at or slightly below your eye height when you are comfortably seated.
  However, be sure to optimize your monitor height so the line of sight between your eyes and the center of the monitor suits your preferences for visual distance and comfortable viewing when your eye muscles are in a relaxed state.

• Tilt: Adjust the tilt of your monitor to optimize the appearance of the screen content and to accommodate your preferred head and neck posture.

• General location: Position your monitor to avoid glare or reflections on the screen from overhead lighting or nearby windows.

The following are some other tips for comfortable viewing of your monitor:

• Use adequate lighting for the type of work you are performing.
• Use the monitor brightness, contrast, and image adjustment controls, if equipped, to optimize the image on your screen to meet your visual preferences.
• Keep your monitor screen clean so you can focus on the screen’s contents.

Any concentrated and sustained visual activity can be tiring for your eyes. Be sure to periodically look away from your monitor screen and focus on a far object to allow your eye muscles to relax. If you have questions about eye fatigue or visual discomfort, consult a vision care specialist for advice.
Quick tips for healthy work habits
The following information is a summary of some important factors to consider to help you remain comfortable and productive while you use your computer.

• Good posture starts with equipment setup: The layout of your work area and the setup of your computer equipment has a large effect on your posture while using your computer. Be sure to optimize the position and orientation of your equipment by following the tips outlined in “Arranging your work area ” on pages 2-1 so you can maintain a comfortable and productive posture. Also, be sure to use the adjustment capabilities of your computer components and office furniture to best suit your preferences now and as your preferences change over time.
• Minor changes in posture can help avoid discomfort: The longer you sit and work in front of your computer, the more important it is to observe your working posture. Avoid summing any one posture for an extended period of time. Periodically make minor modifications in your posture to help deter any discomforts that might arise. Make use of any adjustments that your office furniture or equipment provided to accommodate changes in posture
• Short, periodic breaks help ensure healthy computing: Because computing is primarily a static activity, it is particularly important to take short breaks from your work. Periodically, stand up in front of your work area, stretch, walk for a drink of water, or otherwise take a short break from using your computer. A short break from work gives your body a welcome change in posture and helps to ensure you remain comfortable and productive while you do work.

Eye Strain

• Break Times
  Computer users should take some time away from the screen, especially if working for prolonged hours. Generally, it is recommended to take short breaks (5 – 15 min.) after 1 –2 hours of continuous computer work. Taking short and frequent breaks is more advised than longer breaks.

• Looking at Distant Objects
  Users often blink less when in front of the monitor screen. To minimize eye strain and dryness, users should rest the eye periodically by focusing on objects that are far away.

• Eye Exercises:
  1. Alternate looking up and looking down while keeping the body and head upright.
  2. Slowly roll your eyes to look to the left and right.
  3. Roll eyes to look at objects in the upper right corner and then on the lower right. Do the same thing to look at objects on the upper left and lower left.

Low Blue Light

Concerns about blue light affecting eye health have risen over the years. Blue light has wavelengths between 300 nm to 500 nm. The monitors have a factory setting that reduces
blue light emissions.
Press the Low blue Light key to enable/disable Low blue light.

Adjusting your monitor image
This section describes the user control features used to adjust your monitor image.
Using the direct access controls
The direct access controls can be used when the On-Screen Display (OSD) is not displayed.
Table 2-1. Direct access controls

****

Note:

• When the Brightness adjustment bar is displayed on the screen, use + or – for adjustment.
• When the Contrast adjustment bar is displayed on the screen, use + or – for adjustments.
• Low Blue Light Mode is reducing the blue light content.
• The use of Extreme Mode (response time) may result in reduced display quality when fast-moving video graphics are displayed. Users should check Extreme Mode (response time) to verify if it is compatible with any applications they would like to use it.

Selecting a supported display mode

The display mode the monitor uses is controlled by the computer. Therefore, refer to your computer documentation for details on how to change display modes.
The image size, position, and shape might change when the display mode changes.
Unlike CRT monitors, which require a high refresh rate to minimize flicker, LCD or Flat Panel technology is inherently flicker-free.
Note: If your system has previously been used with a CRT monitor and is currently configured to a display mode outside the range of this monitor, you may need to re-attach the CRT monitor temporarily until you have re-configured the system; preferably to 1920×1080 at 60Hz, which is the Native Resolution Display mode.
Response time: 6ms with overdrive @60Hz
Table 2-3. Factory set display modes

Note: The video signal source connected to L15 needs to support USB-C DP Alt-mode video output.
Understanding power management
Power management is invoked when the computer recognizes that you have not used your mouse or keyboard for a user-definable period. There are several states as described in the table below.
For optimal performance, switch off your monitor at the end of each working day, or whenever you expect to leave it unused for long periods during the day.
