To test 3D picture quality, you must be wearing 3D glasses and the glasses and the TV must be paired.
3D is not available in the U.S.A. and Canada and is only available on LED 6200 series TVs or higher.
Before you review the list of problems and solutions below, use 3D Picture Test to determine if the
problem is caused by the TV. The 3D Picture Test displays a high definition picture you can examine
for flaws or faults. If the test picture does not appear or there is noise or distortion, the TV may have
a problem. Contact Samsung's Call Center for assistance. If the test picture is displayed properly,
there may be a problem with an external device. Please check the connections. If the problem persists,
check the signal strength or refer to the external device's user manual.
The Problem
The 3D glasses are not
working correctly.
I can't see 3D images
clearly.
The batteries in the 3D
glasses are flat.
> 3D Picture Test
Make sure the glasses are powered on.
The 3D feature may not work properly if there is another 3D product or an
electronic device running nearby.
If there is a problem, keep other electronic devices as far away as possible from
the 3D Active Glasses.
The ideal viewing distance is three times or more the height of the screen.
We also recommend watching 3D content with your eyes level with the screen.
Turn off the 3D glasses when they are not in use. If you leave the 3D glasses on,
the battery lifespan is shortened.
