UPDATE!-Alright so we have the Novastar MCTRL4K. From what we can tell it does not scale or convert. It processes signal for LED Panels and that's it.
We purchased the Blackmagic Terenex AV. This is basically a plug and play. Took a 720P HDSDI(or any HD input for that matter) into it, pressed the output button, pressed the UltraHD button on told it frame rate, outputted HDMI to the Novastar Processor, and we have 4K over a single HDMI. I hope my troubles are able to help someone in the future. Thanks guys!
