DOT CLOCK

(RGB only)

Periodic striped pattern interference

(noise) may occur when a striped

pattern such as the one below is

projected. If this happens, use the

I and H buttons to adjust so that

any such noise is minimised.

CLOCK PHASE

(RGB only)

Adjust the DOT CLOCK setting first

before carrying out this adjustment.

Use the I and H buttons to adjust so

that the noise level is least noticeable.

KEYSTONE

Before carrying out keystone

correction, 1) adjust the forward/back

angle of tilt of the projector by pressing

the adjuster buttons and 2) press the

AUTO SETUP buttons to correct

vertical keystone distortion. (page 27)

The vertical keystone distortion will be

automatically corrected by the

projectors automatic setup function.

However the horizontal distortion needs

to be corrected or a tilted screen needs

to be adjusted manually by following

any of the procedures in the table.

NOTE:

B

If signals with a dot clock

frequency of 100 MHz or higher

are being input, interference may

not be completely eliminated when

the DOT CLOCK and CLOCK

PHASE adjustments are carried

out.

If you press the AUTO SETUP button

after correcting the keystone distortion

manually, the automatic keystone

correction function will operate and the

corrected picture will return to its

previous incorrect condition. In addition,

if you change the input signal and press

the AUTO SETUP button, the keystone

correction may be cancelled depending

on the type of signal and the angle of tilt

of the projector. To prevent them from

happening, you can set “AUTO

KEYSTONE” in the OPTION menu to

“OFF”

B

The greater the correction of keystone

distortion amount, the more the picture

quality will deteriorate, and the harder it

will become to achieve a good level of

focus. To obtain the best picture quality,

set up the projector and screen in such

a way that the amount of keystone

correction required is as minimal as

1 2 ... 36 37 38 39 40 41 42 43 44 45 46 ... 66 67
