Thread: 5" tft with RGB inputs

You've got two basic types of RGB interfaces. The first, RGB, uses 3 wires- Red, Green, Blue. It combines the horizontal and vertical sync on the green wire. If the controller is this type, then you would have to get a sync combiner to put convert the VGA signal to RGB. These can cost some serious cash.

RGBHV, or the higher quality of the two, uses 5 wires. It has the standard Red, Green, and Blue, but also uses a (usually) white and yellow cable for sending isolated horizontal and vertical signals. If your controller has 5 inputs, then I would assume it is RGBHV, but I can't be sure without seeing it and looking through documentation. If it is, then you can use that schmatic or a cheap adapter cable.



It's about $20. It's very well fabricated and provides noise suppression. I've used them before and they're well worth the investment. Probably too much information... Oh well.

a quick tip about those BNC cables... be careful with the bnc connectors and the single wires... they dont have any sort of strain relief.

(Ive gone thru plenty)
