Video
A display’s native resolution is its width and height measured in pixels. Generally, for best performance, an image displayed on this
monitor will look best when your computer’s output resolution matches this monitor’s native resolution, which is 1920x1080.
For computer output at non-native resolutions, the monitor will scale the video to its panel’s native resolution. It will involve stretching or
compressing the dimensions X and Y to fit the display’s native resolution. An unavoidable byproduct of the scaling algorithms is a loss of
fidelity when the computer’s output video image is scaled by the monitor to fit the display. This loss of fidelity is most apparent when
viewing feature-rich images at close distances (e.g., images containing small-font text)
Your touch monitor will likely not require video adjustments. However, for an analog VGA video, variations in video graphic card outputs
may require user adjustments through the OSD to optimize the quality of the touch monitor’s displayed image. These adjustments are
stored by the touch monitor. Moreover, in order to decrease the requirements for adjusting the timing sequence of different video modes,
the monitor will properly scale and display some most common video timing sequence modes in the video industry. Refer to the technical
specification of the monitor on the website address http://www.elotouch.com for a list of these Preset Video Modes.
On-screen display (OSD)
There are two buttons on the back of the monitor whose functions are as follows:

The ET2270L/ET2470L/ET2770L have passed the TUV Rhine Low Blue Light and Flicker-free Certification and can lower down the
damage posed by the monitor on human eyes. For the details, please refer to the follows.
Low Blue Light (Software Solution)
The display industry has developed two different methods to achieve the blue light reduction: a software solution and a hardware solution.
The software solution usually reduces the blue light by lowering the blue channel emission or applying an anti-blue light filter.
ET2270L/ET2470L/ET2770L implement Low Blue Light by lowering the blue channel emission.
TÜV Rheinland has tested this product in order to ascertain the product can offer an effective reduction of hazardous blue light.
The keyword “Low Blue Light (Software Solution)" confirms that the product satisfies TÜV Rheinland's test criteria.
For the enabling method of LOW Blue Light, please refer to the “OSD” operating instructions

Flicker Free
TÜV Rheinland has tested this product to ascertain whether the display produces visibly and invisible flicker for the human eye and
therefore strains the eye of the user.
The keyword "Flicker Free" confirms that the device has no visible and invisible flicker defined in this standard within the range of 0 - 3000
Hz under various brightness settings.
Break time, eye excises, Look at distance objects, Neck Exercises
To reduce your risk for computer vision syndrome and neck, back and shoulder pain, take frequent screen breaks during your work day
(at least one 10-minute break every hour). During these breaks, stand up, move about and stretch your arms, legs, back, neck and
shoulders to reduce tension and muscle fatigue. Another cause of computer eye strain is focusing fatigue. To reduce your risk of tiring
your eyes by constantly focusing on your screen, look away from your computer at least every 20 minutes and gaze at a distant object (at
least 20 feet away) for at least 20 seconds. Some eye doctors call this the "20-20-20 rule." Looking far away relaxes the focusing muscle
inside the eye to reduce fatigue. Another exercise is to look far away at an object for 10-15 seconds, then gaze at something up close for
10-15 seconds. Then look back at the distant object. Do this 10 times. This exercise reduces the risk of your eyes' focusing ability to "lock
up" (a condition called accommodative spasm) after prolonged computer work
Exercises for the eyes
1. Keep the body and the head upright. Turn the eyes up to look at the ceiling. then turn down to look at the floor.
2. Turn the eyes left and right slowly to look at objects on the two sides.
3. Turn the eyes to look at objects at the right upper direction and then the night lower direction. Repeat for the left upper and left
lower directions.
Exercises for the neck
Keep the arms relaxed at your side.
Bend your head forward slightly to stretch the neck
Hold for 5 seconds.
Keep the arms relaxed at your side.
Turn the head to one side and hold for 5 seconds.
Repeat for the other side.
Keep the arms relaxed at your side.
Swing the head to the left and hold for 5 seconds.
Repeat for the other side.
