5Connecting the VP-420/VP-421 PC/HD Scaler

To connect your VP-420/VP-421, as illustrated in the example in Figure 3 do the following:

1.Connect a computer graphics or HDTV source to the PC/HD INPUT 15-pin HD connector.

2.Connect to the PC/HD OUTPUT 15-pin HD connector to a computer graphics or HDTV acceptor as follows:

￿When connecting to an XGA acceptor (RGBHV), then connect to the acceptor’s XGA connector

￿When connecting to a component acceptor (YPbPr), then connect as shown in Table 3
