S.INPUT CL32PD2100 (with NR=off). DVD output signal includes noise equivalent to picture
SOFTER When DVD signal input through AV1, Front by frequency.
CVBS or S-VHS, picture is soft. CL32PD2100 displays a picture more detail with NR=off
than 32PD3000 but DVD noise is also emphasized especially
seeing sky, you can see dot noise on
CL32PD2100.
32PD3000 is filtered noise so you cannot see noise but a
picture is also becoming softer.
ADVICE;
CVBS and S-input is not good for demonstration. Because
almost all DVD has RGB, please use RGB for demo or
YCbCr/YpbPr instead (new feature) RGB input of 32PD3000
is more crisp and less noise than CL32PD2100.
