Image Appears Too Light Or Too Dark; Image Is Dim When Monitor Is First Turned On; Bright Dots On The Monitor - Silicon Graphics 1600SW Owner's Manual

Image Appears Too Light or Too Dark

The images on flat panel monitors look lighter or darker when viewed
from different angles (especially from highly oblique angles). Check
that your line of sight is as close to perpendicular as possible. See
"Recommended Use and Viewing Angles" on page EN-11 and
Table 3-1.
Considerable development has been done to ensure that your flat
panel monitor has the widest possible viewing angles without
compromising such features as displaying fast-moving video. For
more technical information, see "Technical Specifications" on
page EN-24.

Image Is Dim When Monitor Is First Turned On

It takes about one minute for flat panel monitors to warm up to full
brightness from a cold start, so at first the image may appear dim or
faded. This is because the ambient air temperature affects the startup
brightness of the flat panel monitor. For example, when the air
° °
temperature is about 77 F (25 C), the panel is initially at about 80% of
° °
its maximum brightness. However, at 50 F (10 C), the light output can
start out at as little as 30% of its maximum.
Eventually, though, as the backlight lamps warm up, the monitor
should reach its maximum brightness, as long as it is being operated
within the proper temperature range. See Table 3-4 for the operating
temperature range.

Bright Dots on the Monitor

Occasionally you may notice some bright dots on the monitor that
remain in the same place regardless of the image being displayed on
the screen. This is intrinsic to thin-film transistor (TFT) liquid crystal
displays (LCDs) and does not indicate a defective screen.
