Optimum Picture Quality

Optimum Picture Quality and Afterimage Burn-in Prevention

•• Due to the nature of the manufacturing of this product, approximately 1 pixel per million (1ppm) may be brighter or darker on the panel. This does not affect product performance.

-- The number of sub-pixels by panel type: 6,220,800

•• Run Auto Adjustment to improve the picture quality. If noise is still found even after auto adjustment, adjust Coarse or Fine.

•• Leaving the screen fixed on a stationary image for an extended period of time may cause afterimage burn-in or defective pixels.

-- Activate power-saving mode or a dynamic screen saver if you will not be using the product for an extended period of time.

Prevention of Afterimage Burn-in

Setting the anti-screen burn-in pattern

The anti-screen burn-in pattern automatically operates in standby mode.

•• Disabling the anti-screen burn-in pattern

On the remote control, press 2 → 2 → 7 → CH → 0.

If the remote control sensor blinks once, the pattern is disabled.

•• Enabling the anti-screen burn-in pattern

On the remote control, press 2 → 2 → 7 → CH → 0.

If the remote control sensor blinks twice, the pattern is enabled.

――When the screen is turned off, the anti-screen burn-in pattern will operate for two hours. ――Keeping the anti-screen burn-in pattern on requires extra power consumption.

What is afterimage burn-in?

Afterimage burn-in should not occur when the LCD panel is operating normally. Normal operation refers to a continuously changing video pattern. If the LCD panel displays a fixed pattern for an extended period of time (more than 12 hours), a slight voltage difference may occur between the electrodes in pixels that control the liquid crystals.

Such a voltage difference between electrodes increases with time and makes the liquid crystals thinner. When this occurs, a previous image can remain on the screen when the pattern changes. To prevent this, the accumulated voltage difference should be reduced.

――Afterimage burn-in should not occur when an LCD panel is operating in proper conditions.
