FEATURES

„DIGITAL VNR
The DIGITAL VNR function cuts down the 
amount of ‘noise’ (‘snow’ or interference) in 
the original picture.
You can choose from the three DIGITAL 
VNR function settings of AUTO, MIN and 
MAX.
AUTO(LOW)/AUTO(HIGH):
The TV will automatically adjust the level of 
the DIGITAL VNR effect to match the 
amount of noise in the picture, giving you the 
best possible picture.
• If you set the DIGITAL VNR effect too 
high it can make the picture less sharp. It is 
recommended you use the AUTO(LOW) 
setting if you can. If you set the DIGITAL 
VNR function to AUTO(LOW) but still 
notice some noise, change the setting from 
AUTO(LOW) to AUTO(HIGH).
MIN:
The level of the DIGITAL VNR effect is set 
to the minimum. If you set the DIGITAL 
VNR function to AUTO(LOW) but feel that 
the sharpness of the original picture has not 
been reproduced fully, change the setting 
from AUTO(LOW) to MIN.
• The MIN setting is not suitable for low-
quality pictures which contain a lot of 
noise.MAX:
The level of the DIGITAL VNR effect is set 
to the maximum. If you set the DIGITAL 
VNR function to AUTO(HIGH) but still 
notice some noise, change the setting from 
AUTO(HIGH) to MAX.
• The MAX setting is not suitable for high-
quality pictures which contain very little 
noise.
„Super DigiPure
The Super DigiPure function uses the latest 
in digital technology to give you a natural-
looking picture. The Super DigiPure function 
includes the following two functions.
DigiPure function:
This function helps to create a natural-
looking picture by eliminating unnecessary 
edges from high-contrast and crisp images. 
For images with low-contrast, edges are 
added to produce a sharper, more detailed 
picture.
You can choose from the three DigiPure 
function settings of AUTO, MIN and MAX.
• If you set the DigiPure effect too high on 
a low-quality picture that contains a lot of 
noise, this may actually make the noise 
worse. We recommend you use the 
AUTO setting if you can.
Picture motion compensation 
function:
This function displays fast-moving pictures 
(for example, the players or ball in a football 
game) more smoothly and naturally on the 
screen.
• The effect level of the picture motion 
compensation function cannot be 
changed. The effect level is the same no 
matter which of the AUTO, MIN or MAX 
settings is used.
AUTO:
The TV will automatically adjust the level of 
the DigiPure effect to match the amount of 
noise in the picture, giving the best possible 
picture.
