MX 1 In 4 Out DVI Distribution Splitter with Digital Audio (MX-3189)

Driving multiple displays from a single source normally means either running separate cables with signal degradation over distance or buying a dedicated splitter built for the job - this is that dedicated splitter, taking one DVI input and distributing it cleanly to four independent outputs, each carrying the full video signal plus digital audio rather than video alone. That makes it suited to installations like a retail display wall, a control room with multiple monitors showing the same feed, or a presentation setup that needs several screens in sync from one source. Unlike a passive cable splitter, a proper distribution unit like this actively regenerates the signal on each output, so picture quality doesn't degrade the way it would running several displays off a basic passive splitter.
