. In
the Ambiglow “Auto”, the intensity is
variable and depends on the actual
screen image. For example, if the movie
has dark images, then the intensity will
be less. Note that in the Ambiglow
“SmartBiasLight” mode, the glow of light
is static and not linked to screen image.
Q5. Ambiglow is set to brightest, but I
cannot see the glow on the wall.
Ans.: 1. Please ensure that your monitor is
placed not more than 10 cm to 15
cm distance from the wall or a solid
flat surface
10 ~ 15 cm
2. We recommend a flat, white or
neutral colored wall/surface for the
best viewing experience.
3. We recommend that you dim the
room lighting to minimum, or turn it
off for the best Ambiglow effect.
Q6. Why does Ambiglow always show
white color glow even when the
movies, images and games are colorful?
Ans.: Please ensure that your Ambiglow
setting in OSD menu is set on AUTO
which will activate the Ambiglow in full
color glow mode to match the color of
screen images.
