Hi all-

I tried to search and could not find an answer. I just got my PDP-5070 (bought it from Invision Displays). I notice that on diagonal lines, the outlines seem to be jagged (not smooth). My LCD does not do this amd I saw a Panasonic and it did not do it either. I read somewhere it has something to do with interpolation. Is this just something we live with for the Pio PQ?

Also, I am noticing that on HD content every so often the picture seems to "shudder". Hard to explain but it seems as if the picture pauses for a a flash (very, very, very short time, less than a second) and then starts. I am connecting via a DCT-6416 box. It does not always do it and I believe this is a signal not a TV issue. Any other owners experiencing this?

The "shudder" you are describing definately sounds like an issue from your source signal and not your Pioneer set. The only thing I currently have hooked up to my set is an Oppo970 DVD player, which I am using for breakin, and I see no issues of shuddering. As for the jagged lines, what type of feed are you giving your set? Are you having the DCT-6416 process it to 720p and then passing it to your Pioneer? If so, try just passing the sources native signal, unprocessed, to the Pioneer and let it do the deinterlacing. You could be getting a little noise due to processing the signal multiple times. Do you have a picture of what you are talking about for jagged lines, as I don't think I have seen those on my display yet.

Thanks Dustin.

I actually saw the jagged lines on the Elite and on the 5070 at Best Buy. Go to this site and you will see what I mean:

I do not know how to modify what the DCT passes on.

Hey D-nice! I see that PM functionality is not enabled for you. I will post my settings tomorrow but have a question for you.

I have heard of the delay between audio and video on the 5070. My plan was to not use the speaker, send the video from the DVR / HD tuner to the TV (component or HDMI, not sure yet) and then the sound from the DVR/HD tuner to the receiver (similar to connecting a DVD player) via optical or analog. Will this result in adelay?

The user manual says that if you send the sound from TV to receiver there may be a delay, but is mute on a delay if using a cable box.

Thoughts?

I don't think I have seen jagged lines like that to date on my Pioneer 5070HD. That is pretty noticable...I to would wonder if it has something to do with one of your settings.

Pinito,

Post your settings here when you get a chance, and I will do the same as soon as I get a chance. I think D-Nice is waiting to see your settings as well.

Hello all ...

First of all, I'd like to say that even though this is my first post, I've been reading the Pioneer info on this forum for at least a year. You could say I'm addicted to it right now ... so much valuable information for a novice like myself searching for his first HDTV. (I currently own a 27" CRT). A big thank you to ALL of you. I hope to end my search this summer (before football season starts). Since I first started reading these threads, I've become a big fan of Pioneer's plasmas.

To get to the point of this post ... I was in a store today that displayed a Pioneer 50" 720p 5080 directly below a 50" 1080p Elite 110FD. I wouldn't expect these TVs to look identical to each other (and they didn't), but the 5080 definitely had a case of the jaggies going on. When I went into the store, I was seriously considering buying the 5080, but seeing the jaggies on it made me back off. (And by the way, I did notice the same thing going on earlier in the year with the 5080 at a Best Buy store ... which also caused me to back off at that time). The salesperson who I dealt with (who I consider very knowledgeable) thought that it might be possible to make the jaggies less noticeable by tweaking some of the settings ... although we ran out of time to do any adjusting as the store closed while we were still talking. So now I have to wait until Monday at the earliest to go back there.

So I'm wondering if this is a phenomenon that might happen due to the 720p resolution (vs. the 1080p of the 110FD)? Or can it indeed be tweaked out by adjusting the settings? I would love to hear some 5080 (or maybe even 4280) owner's thoughts on this.

Thank you!

bump ... (I sort of expected this post to get lost in the shuffle since I'm posting to an old thread in the middle of a major 9G KURO orgy).

Personally, I think the jaggies I'm seeing in the 720p and not in the 1080p is due to resolution ... more "dots" making the 1080p appear smoother and more defined than the 720p.
