3rd row entertainment for 3 kids

[Xpresso]

We've got a long-haul dilemma. We take epic road trips with the 3 little ones, but our current setup only entertains the second row with the built-in screens. We tried the FireTV route, but the connection is spotty and downloads are a nightmare. The USB movie system for the second row is awesome, but ideally, we'd project it to a third-party screen with HDMI in the third row. Anyone cracked the code on mirroring those backseat screens? The car's FireTVs only output HDMI, and a Firestick on the third screen only mirrors phones/tablets. The second-row screens can mirror each other, so there's gotta be a way! Is it internal WiFi or a cable? Help!!!

An HDMI splitter could be a solution. You could connect your source device (like a streaming box) to the splitter, then run separate HDMI cables to each display in your car.
