A projector resolution when the unit is able to project an image greater than its native resolution.
A method of reducing data from a higher resolution to enable images to be projected by a projector with lower true resolution. Most SVGA (800x600) projectors offer compression capabilities for handling images from XGA (1024x768 pixels) i.e. a higher resolution than their true (or native) resolution.
Anytime a projector can accept a higher resolution signal and compress the data down to fit its true resolution. Quality of compressed images varies tremendously. Most but not all projectors offer compressed resolution for handling higher res then their true resolution. Some use simple "line dropping" schemes while others achieve varying degrees of higher quality with different "intelligent" algorithms.
Compressed Resolution: Most projectors automatically accept images that are of greater resolution than the native (true) resolution of the projector. The resulting image is scaled to fit the native resolution of the projector using a variety of scaling algorithms. Not all projectors use the same compression algorithms; therefore, the quality of compression can vary. The nature of compression in a digital device means that some image content is lost.
A process in which a projector accepts a higher resolution signal and compresses the data down to fit its true resolution. Quality of compressed images varies tremendously. Many projectors offer compressed resolution for handling higher resolution than their true resolution. Some use a simple "line dropping" methods while others achieve varying degrees of higher quality with different "intelligent" algorithms.
An electronic method of reducing the resolution of a signal to operate on a lower resolution device. An example would be an LCD Projector that has a maximum resolution of 800x600 pixels being used with a computer that is displaying 1024x768 resolution. The image quality will be reduced when compressed.
