I want to display my Alpine HCE-104 backup cam on my Lilliput UM1010/C/T. The cam has a RCA output, but my monitor is USB. My computer motherboard is ASUS AT5IONT-I and has PCIe X4 PCI express 4 slot for video. I was thinking of adding a TV tuner card, but can't find any PCIe X4 cards under two thousand dollars. Anyone know of any low priced video cards that will work?
