Small bright dots appear on your TFT display when you
turn on your computer.
Small bright dots may appear on your screen display when
you turn on your PC. Your display contains an extremely
large number of thin-film transistors (TFT) and is
manufactured using high-precision technology. Any small
bright dots that may appear on your display are an intrinsic
characteristic of the TFT manufacturing technology. Over a
period of time, and depending on the usage of the computer,
the brightness of the screen will deteriorate. This is also an
intrinsic characteristic of the screen technology. When the
computer is operated on battery power, the screen will dim
and you may not be able to increase the brightness of the
screen while on battery power.
