| In addition, the sync signals may need to be buffered (using a 74hc244 chip) depending on the monitor being used. | In addition, the sync signals may need to be buffered (using a 74hc244 chip) depending on the monitor being used. | ||

| If you follow either of the two sync signals you will eventually come to this small chip. This is where the two sync signals become Composite Sync. If you need Composite Sync it is not recommended you get it from here because of the MacroVision copy protection signal which also gets mixed in when needed. | If you follow either of the two sync signals you will eventually come to this small chip.

| You can make your own Composite Sync signal with two very simple components. First, run the Horizontal Sync through a 1N4148 diode (very common - can be found at Radio Shack). Second, run the Vertical Sync through a 820 Ohm resistor. Once the two signals have been conditioned this way then you can simply splice them together. | You can make your own Composite Sync signal with two very simple components.
