Sony's LMD-4420 is a compact and lightweight quad 4-inch LCD monitor unit that is less than 2 inches deep. The rack-mountable assembly is only 2 standard rack units in height with a tilt function and is ideal for mounting in production vehicles and studios. The monitors accept both NTSC and PAL composite signals with automatic recognition. The LMD-4420 is the upgraded model from the LMD-440. It offers greater contrast ratio and a wider viewing angle than the previous model.
