All video transmissions are done with a certain number of pixels, or resolutions. Converting a video’s signal from one resolution to another is called scaling. While many video devices have built-in scaling, there are a number of those that do not have any scaling or what is included does not work for certain applications. ProAudio.com would like to offer a variety of scalers for your needs. In the same vein, scalers containing scan converters are becoming more common; however, you may need a separate device that is specifically designed to convert the refresh rate of the video. In this case, please browse our standalone scan converters. For more basic signal conversion, see our simple converters section.
