Geometric Correction Tool 4

The Geometric Correction Tool 4 (hereafter referred to as "the software") is designed to expand the use of NEC projectors in unique settings. The software is not included with the projector and must be downloaded separately. Great care has been taken to ensure that the software will work properly. However, use conditions vary depending on projector you use, projector application, or signals used. For this reason, NEC Display Solutions does not warrant that the functions contained in the software will meet your requirements. Before using the software, read the ReadMe file which provides notes and operation procedures. In no event shall NEC Display Solutions be liable for loss of business or profits, or for any indirect, incidental or consequential damages arising from the use of or inability to use the software. The software is owned and licensed by NEC Display Solutions. The software and its related materials are provided " as is ".

Version : Ver. 2.21


The Geometric Correction Tool 4 (hereafter called " the software ") corrects geometrical distortion of an image projected onto a special shaped screen such as a cylindrical screen, and a spherical screen from an NEC projector. This program allows you to control the projector via a computer (hereafter called " PC ").
