Yes. Either one is OK.

forward or backward from vertical. There are
special, option, mounting brackets for 5, 10,

It may mean something isn't right. The Standby
LED flashes for a short period during initial
power-up. When it is steady, the unit is waiting
for an ON command. The IR Remote Sensor
LED flashes whenever the unit detects infra-red
radiation, whether it comes from the remote
control or not.
A dark display can be caused by many things;
check them all. Start by displaying the White
internal Test Pattern.
• Black Level and White Level: Check them
both. Poorly set levels, or using a different
computer, can change brightness. See page
3-20.
• Color Balance: Check the color balance
using the internal test patterns. See page
3-34.

testing.
