UltraHD may have arrived but not everyone will be ditching their existing HD screens in favor of 4K overnight.  As such, the ability to support a combination of 4K and 1080p HD displays within the same distribution is an important consideration, especially given the resolution conflicts that effect systems including screens of different capabilities. Placed between a display and a source device, this EXP-CON-4K-DD video scaler and digital audio converter (DAC) is designed to adjust resolution and audio from an incoming HDMI source and scale output to a level compatible with display capabilities. The EXP-CON-4K-DD represents the ideal solution to the growing challenge of how to simply and reliably accommodate both HD and 4K sources and displays within a multi-zone residential or commercial distribution.
