Understanding Native Resolution For Your Home Theater Projector

What is Native Resolution for your Home Theater Projector?

To understand what is native resolution, lets start with an understanding of the concept of 'resolution'. Resolution is concerned with the mapping of the information within a picture or image by the dot area.

The smaller the dots, and the more densely packed it is, the greater the resolution, since the mapping of dots as measured in pixels constitutes the data for reproducing the images in video outputs of home theater and other viewing systems. This data processing capability of the projector, as measured in pixels, is what constitutes native resolution.

For high definition home theater projector pictures with good resolution, both the native resolution of the projector should match the resolution of the video signal or video input, failing which, distortion of the images is likely. Native resolution of home theater projectors is measured in two dimension figures with current capabilities ranging from (640480, 800600, 1024768, 16001200) for 4:3 image aspect ratios and the occasional odd resolutions like 12801024.

Thus, if projectors of 1280X 1024 native resolution were to map a video signal of resolution 1024 X 768, there would errors and likely distortion in the image. To effectively combat or otherwise provide for different standards, most home theater video projectors come with capabilities of multiple resolution standards, though it is most likely to be multiples of the lower resolution values.
