This easy to use projector with the light compact body delivers amazingly high brightness of 3,000 ANSI lumens. With the advanced functions of 3D Reform, Automatic Vertical Keystone Correction and Wall Colour Correction, the VT770 can be installed anywhere you like. The projector is equipped with a full set of input terminals, built-in stereo speakers and security functions - prefect for education or business, classrooms, presentations and meetings.
Easier installation, Advanced 3D Reform
Trapezoidal distortions of images projected from an angled position can easily be corrected by combining the ordinary 3D Reform function and the automatic vertical keystone correction function.

When an image is projected from the left

  1. The projector senses its vertical inclination and corrects projected images automatically. (Automatic keystone correction)With this operation, both the right and left sides of the projected image can be corrected to an almost right angle.
  2. Then align the shorter side of the image on the left to a frame of the screen.
  3. When you press the "Horizontal" key of the "Keystone Correction Menu", you can adjust the longer side of the image to make both the top and bottom sides parallel to obtain a square image.Since the ordinary keystone correction function using the 4-point correction method is also available, you can choose either method-whichever is easier to correct images depending on the projection environment.
Wall Colour Correction with 7 types of wall colour options can correct images according to the wall colour, such as a blackboard, etc.
When projecting images on a classroom blackboard without a screen, image colours will be tinged with green. Since colour data for such occasions as projection on a blackboard or a coloured wall were previously incorporated in the VT770, colours and tones of projected images and characters will be similar to ones that are projected on a white screen if the "Blackboard Mode" is selected. In addition, choose between 6 other types from the colour menu including colours of walls or room partitions.
Blackboard Mode
Multiple input terminals and built-in stereo speaker
Input terminals for two computer systems (Mini D-Sub 15 Pin), component, video, S-video, and audio are standard. Furthermore, the projector is equipped with monitor output terminals (Mini D-Sub 15 pin) and audio output terminals, and with the built-in 5W + 5W stereo speaker, high quality images and sounds can be enjoyed.
Preset function adjusts and stores specific colours
The Video Image Correction function adjusts images according to the video source, such as presentations or movies. Select one of five options for video image modes. Up to five settings can be adjusted and stored in memory.
Viewer function for projector only presentations
Presentation documents from a PC and stored on a flash memory card*1 or images from a digital camera and stored on a flash memory card*2 can be reproduced with the Viewer function, for presentations without a PC.
*1 Use commercially available PCMCIA Type II(ATA specification) flash memory cards
*2 Some flash memory cards may not be available for reproducing.
USB Storage using commercially available USB memory
Enhance the viewer and security features of the VT770 with commercially available USB memory. Connect a USB memory card reader with the VT770 and use a memory card to manage data or as a protection key.

Security Function
The Key Lock function disables the operation buttons so the unit can only be operated via the remote control. Password protection prevents changes to the settings* and the PC card authentication settings prevent anyone from using the projector without authorization, which is effective for preventing theft. Improper operation by students in a classroom can also be prevented.

Quick start & Quick shutoff
The quick start & quick shutoff function means you can install or dismantle the projector without delay. Fifteen seconds after turning on the power, the projector is ready to project PC or video images. When you're finished, the fan stops 10 seconds after turning off the power, so you can dismantle the projector quickly after the conference or class.
