Video Processors
Scalers and line doublers, generically referred to as video processors, used to be the province of the ultraelite. Prices have dropped dramatically in recent years, however, thanks to the proliferation of models and vendors. While CRT front projectors practically require a video processor to create a decent picture, most digital displays now include some form of video processing already. You might still choose to add a better-quality external model to improve the picture even further. The processor will even route all your signals through one connection to the display, thus eliminating wire clutter.
