I have a new old stock Lumagen Vision video processor. I opened it up just to test the functionality and everything looks great. Literally has 15 minutes of use. Please let me know if you have any questions and thanks for looking.

The Vision™ Video Processor provides exceptional deinterlacing and scaling. Unlike many video processors which are limited to a single, or a few, output resolutions, it allows output timing to be precisely tuned to the projector’s, or High-Definition Television’s (HDTV), optimal configuration.

Most projectors and HDTV's provide a good picture for high-definition sources, but they often fall short for standard definition (SDTV) sources. The Vision Video Processor corrects this shortcoming and makes SDTV sources look great on these displays.

The deinterlacer converts interlaced video input to progressive video using four input fields to determine the contents of each frame. For progressive material, the original frames are reassembled using 3:2, or 2:2, pull-down reconstruction. For video material, interlaced-video artifacts are detected on a per-pixel basis. Using the result of this artifact detection, the source pixels are merged, or blended, into the best possible progressive image.

Proprietary detail-enhancing algorithms are used to scale the progressive video to the optimal resolution. The video is over-sampled to enhance the image quality. Video oversampling provides the same benefit that audio oversampling does for CDs. That is, it produces the most-accurate reproduction of the video signal possible.

When processing is completed, the digital video is converted to analog using three over-sampled 10-bit digital-to-analog converters .

Progressive output is supported from 480p to 1080p in scanline increments, at up to 75 Hertz. Interlaced output is supported at 1080i. In addition, the output vertical-refresh-rate and the aspect ratio are programmable.

Each input has two unique input calibrations and, optionally, two independent output configurations.

A pass-through input is provided for high definition sources. The pass through video is buffered using high-bandwidth video amplifiers. For displays that require a specific sync polarity, discrete sync signals can optionally be converted to the same polarity as the internally generated sync outputs.

Nothing in this world will tick you off more than seeing a vegetarian eating pudding.
