I have the Asus AT5IONT-I mini itx motherboard for my car computer and using the lilliput CM1010/C/T 10.1" touchscreen USB monitor. My motherboard has a PCIe X4 (PCI Express 4) slot and looking for a TV tuner that will fit in there to allow my backup came with RCA out to display on my monitor. I figure I run the RCA into the TV tuner card and my computer will display it on my screen. Does anyone know of any video cards that will do that. The only ones I see are like $2,000 and thats for professional video cards and I only need it for my backup cam. Anyone know any or if I would use an adapter for the PCIe X4 to something?
