WARNING AND PRECAUTION
3D Visual Function Proper Operation Guide
Guide 1: Confirm whether the product presents three-dimensional effect
If there is ghosting, or obvious discomfort when you're viewing stereoscopic
video, please stop your watching and confirm if the settings of 3D products are
correct (such as glasses / 3D TV switch / 3D format switch, etc.). Please reset
the TV, and if the defective phenomenon still appears, please stop using.
Please ask for consulting from the professionals through the customer helpline.
Note: If the 3D TV to be adjusted improperly (for example, when the picture sizes,
color or brightness are different from right to left; the video deviations from up to
bottom; picture crosstalk is too large from left to right), will form three-dimensional
video ghosting, and then caused eyestrain and eye irritation.
Guide 2: Prevent reverse the left and right eye
Which means to prevent the left eye video came into the right eye, right eye video
came into the left eye. Reverse the left and right eye can cause eyestrain and eye
irritation.
Note: The left and right eye reversed direction may be related to 3D glasses
wearing orientation and three-dimensional video transmission format, and other
factors.
Guide 3: Viewing position
We'd better keep our eyes level is parallel to the display pixels ligature,
preferably in the same horizontal plane. The heights differ more, more eyes
fatigue we feel.
We should keep the display center stay at eyes level. PR 3D TV has stricter
requirement for the way of viewing position.
Guide 4: Viewing distance and location
Generally speaking, the three-dimensional video is produced with the imaginary
audiences are in front of the display. For high-definition three-dimensional video,
the recommended front viewing distance is 3 times of the picture height, which is
known as 3H principles. We can not enjoy a comfortable 3D experience with too
far or too near from the display.
Note: The parallax angle becomes larger with a close view distance, when the
parallax angle becomes smaller with a close view distance
Note: When the viewing oblique angle become larger, trapezoidal video
distortion of the picture become more obvious and it will be more difficult to
obtain a valid three-dimensional effect, which will easy to cause eyestrain and
even have drunk experience.
Guide 5: Viewing time
Please interrupt your viewing when you feel uncomfortable. The recommended
continuous viewing time should be less then 1 hour. When you need for
continuous viewing, please have a break of 10 ~15 minutes every hour.
