Daylight View 4 Offers Clear, Crisp Images Even in Bright Surroundings*

The PT-LB78 features Panasonic’s Daylight View 4 technology. Sharp edges are achieved with the “Edge Enhancer Control” and “Gamma Curve Control.” Remarkable detail is provided and per- ceived brightness and contrast are enhanced, so images appear crisp, vivid, 3-dimensional and easy to see even in brightly lit rooms. Daylight View 4 also includes a built-in ambient light sensor that automatically detects room brightness and

adjusts operation accordingly.

* There is no actual change in the rated brightness or contrast ratio.

The projector uses a high-voltage mercury lamp that contains high internal pressure. This lamp

 

may break, emitting a large sound, or fail to illuminate, due to impact or extended use. The length

 

of time that it takes for the lamp to break or fail to illuminate varies greatly depending on individ-

 

ual lamp characteristics and usage conditions.

 

 

 

 

 

The brightness of the lamp will gradually decrease with use.

 

 

The projector includes consumable parts. The frequency of replacement for the lamp and other

 

consumable parts will increase if the projector is subjected to extended, continuous use. For

 

details, please consult a service representative.
