Sony VPL-PX31 Projector Review

2800 ANSI lumens & XGA resolution Combining Sony three-panel LCD technology and a new 200 W UHP lamp, the VPL-PX31 offers an outstanding brightness of 2800 ANSI lumens. To complement their high brightness levels, both the VPL-PX31 and VPL-PX21 utilize three 1.3 inch LCD panels to provide true XGA resolution. Advanced APA {Auto Pixel Alignment) In addition to adjusting dot phase, the new advanced APA also performs shift and size adjustments with the touch of a button.

Silent Fan Noise 34dB achieved with a new fan design, newly engineered cooling structure, and new sapphire glass panel which reduces heat build-up. High Picture PerformanceThe VPL-PX31 uses Sony’s best video processing technology such as the 3D gamma correction previously used exclusively on Sony’s high end installation projectors.

HDTV Ready
The VPL-PX31 can accept a variety of signals for excellent compatibilty with sources both today and tomorrow. Sources selected include, but are not limited to, 480/60p, 575/50p, 1080/50i, 1080&1250/50i, 720/60p, 720/50p.   Flexible Input Capability Composite, S Video, component, YCbCr, YPbPr, and RGB.   New RGB Enhancer For Crisp RGB Images a powerful circuit enhances detail.

Digital Keystone Correction
Corrects for image distortion caused by projecting the image too high relative to the projection angle. This is very useful for presenters on the go.  Advanced APA Function Auto Pixel Alignment allows the users to lock to source signal with the touch of a button for best appearance.  USB Hub Makes digital connectivity simple yet powerful. Connect to other projectors using Projector Station™ Software and control up to 127 different projectors from one computer. This port also enables mouse control from the projector’s remote control.

New Help Function
Make the projector among the most simple to operate, even for a novice.  Digital Zoom Up to four times enlargement for highlighting spreadsheets with small text, flow charts, and other images and drawings.  Laser Pointer Remote Control Draws attention to an image during presentations.

Bi-level Lamp Power Selector
Lamp Mode can be set to High or Low depending on ambient light conditions. The lamps low setting will extend lamp life by approximately two times. Low level light output is approximately 2100 ANSI lumens.

Auto Input Search
When Auto Input SEL is “ON”, the VPL-PX31 searches the input channels and skips “NO INPUT” channels. Auto input is triggered when the input key is pressed or the projector is powered on.  Discrete Input Selection the video and S-video inputs can be discretely selected or accessed via the more traditional toggle command.
