No Difference Between Progressive and Interlaced

03-07-2005, 01:56 AM
I have a sony HTIB dav-fr9 and when I set it to component(and 16:9) and play dvd the picture seems to be just about the same when dvd is set to interlaced. Can't really tell the difference between them. Is this normal? I do have the output from dvd player to tv by way of component. Is it because the tv (KDF55WF655) has a great scaler that it doesn't really matter whether interlaced or progressive? Anyone else experiencing the same thing? Because I thought once connected by component

Forgot to finish.....

Because I thought once connected by component that I would a big improvement in picture quality. This seems to be not the case.

is it an upconverting dvd player? I mean, are you switching between 1080i and 480p or 480p and 480i?

DAV-FR9 has the abiity to output 480I and 480 p. However, the KDF55WF655 converts all input sources no matter what the input resolution to, its either 720p or Virtual 1080I, which I believe its Virtual 1080I. Either way, if the DAV-FR9 is set to progressive scan on an interlaced DVD disc, that right there is a step-up conversion, with a bit of "noise." Then you take the fact that the KDF55WF655 is going to convert any input signal to either 720p or 1080i, that exaggerates the "noise" even more. So basically you're upconverting and already upconverted signal. My advice, turn off the digital picture enhancements (i.e. Edge Enhancment, Black Enhacement, etc.) Go purchase Digital Video Essentials, calibration DVD, and adjust the KDF55WF655 to those patterns and instuctions.

Ok...I don't know if this question has been addressed. Are you, kfarzin, playing a Full-screen DVD or are you playing a widescreen DVD?

I'm playing widescreen dvd 1.85:1. So I should just use the interlaced format on dvd player and 16:9. And get that disc and fine tune the tv then? It's weird though when I put dav-fr9 to prog and 16:9 it will and do a display on that video on tv it will show 480p and 4:3 not 16:9. In interlaced mode 16:9, it will show 480i and 16:9. Haven't figured that one out yet. I've set the wide mode to Full and 4:3 Default to OFF. I've also tried wide mode Normal and 4:3 Default Normal, but it doesn't work.

Virtual resolutions are imaginary... your TV's native res is 720p. It will be best to set your output to 480p in the DVD. It will probably do a slightly better job than if the TV does the deinterlacing, but regardless which device is doing the image processing you'll end up with 720p display. That's why you can't see a difference.
