use the HD/RGB Adjust controls in the Option menu, described on
page 52.
2. The values shown represent where
the approximate center of the
image lies in relation to the total number of pixels available
horizontally or vertically. This varies widely according to the signal;
watch the image while adjusting.
Reset the Lamp Timer ONLY after you replace the lamp. Otherwise, the
rep
orted “Lamp Hours” will be inaccurate.
Do not exceed the recommended lamp life of
2000 hours. An old lamp
becomes increasingly fragile and prone to sudden failure.
