Home Cinema LCD Projector PLV-Z4, 1.778 cm (0.7 ") Wide TFT p-Si x 3
The PLV-Z4 is arguably the most feature-rich home theater projector ever brought to market in its price class. Highlights include the following:
Latest generation high-contrast 1280x720 LCD panels.
Dual iris system with wide range of lumen output to accommodate a variety of viewing needs.
Very long 2.0x zoom range: The zoom range allows a 100" 16:9 image to be displayed anywhere between a 9.8 and 20.0 foot throw distance. This combined with the lens shift capability makes the Z4 adaptable to a wide variety of installation challenges.
Long range vertical and horizontal lens shift: At neutral position, the centerline of the lens intersects the center of the projected image. From that position the image can be raised or lowered vertically 150% of the picture height, or moved laterally 50% of the picture width in either direction.
Six precalibrated color temperature settings.
Six preprogrammed operating modes and four memories for user-programmable custom settings.
On-board color management system that allows selection and modification of individual colors on screen.
LCD panel adjustment to eliminate vertical banding, should it manifest itself in any given unit.
Auto-closing front panel: A motor-driven front panel opens to expose the lens during operation, and automatically closes when the unit is powered down. Over time, this minimizes the amount of dust that can settle on the lens.
Cleaning system: Introduced on the Z3, the Z4 also incorporates a user-cleaning system to remove dust particles that may settle on the LCD panels. There are three small holes in the bottom of the case that remain closed during normal usage. They can be opened to insert the nozzle of a manual squeeze-blower (included with the projector).
Auto-shut down: if the Z4 detects no signal on the active port for a period of five minutes, it automatically shuts down the lamp and closes the lens housing. For those who tend to leave the room and forget to power down the unit, this saves many hours of wasted lamp life.
