What is 3D Reform?
| The new NEC chip is the outcome of exhaustive research by NEC Viewtechnology, the company which developed ASIC scaling for converting pixels. Separate algorithms manage the vertical, horizontal and diagonal correction, giving you more freedom to position the projector wherever you want.
A newly-developed NEC chip provides 3D reform, a keystone correction feature which eliminates trapezoidal distortion. Whereas conventional ‘up-down-left-right’ correction functions are unable to eradicate this kind of distortion, 3D Reform delivers vivid, sharp image projection. If the projected image is distorted, all you have to do is click on the four corners of the screen to activate the keystone correction function, whereupon a rectangular image will be restored. This gives you new freedom in positioning the projector as it can now be placed at an angle to the screen, rather than having to be positioned directly in front of the screen where it may impede the audience’s view.
Projection angles: [up to] 40° vertical and 30° horizontal (25° with the LT240 / 220)
