Problem with DVD picture

I have been having some problems, particularly with watching DVDs. I have been noticing some (I'm not sure of the correct term) artifacting or pixilation of the darker colors. It's more noticeable at certain times, but seems to be happening constantly. It reminds me of poorly compressed video you might find on the net.

The equipment I'm working with is:



They're connected with HDMI cable

In addition, I have trouble getting some DVDs to play in widescreen. For instance, when I leave the tv in <set by program> ratio mode, with certain DVDs it will go widescreen automatically. With other DVDs I have to manually set it to 16:9 and with others I have to use the zoom function or else the black boarders won’t disappear. I was just wondering if there was some science to this. And no, none of the DVDs are full screen.

To anyone who can help me I will give much thanks.

For the dark image pixelation/artifacts, try turning down the sharpness settings.

This may be labled something strange though... Edge Modulation, Scan Improver, Velocity Adjustment, Edge Enhancement or plain old Sharpness. Poke around a bit.

Problem is, depending on the DVD or other source, the artifacts are there due to compression and the nature of digital storage. Increased sharpness settings tend to highlight these, especially with standard definition digital satellite and cable, but also DVD. Also, try increasing your viewing distance a bit. You are feeding a 480 line picture to a 1080 capable display, so the imperfections are only magnified. Some displays are better at cleaning this up than others.

As for your widescreen woes, I'll leave that for someone else to answer. Other folks around here can better explain the mechanics of this than I.

How does it look if you let the TV upconvert, rather than the DVD player? I know they are both LG devices, but the TV might do a better job.

Maybe that's the problem. LG, alias- "Goldstar". But I agree with Bluetech. I suspect the problem is from the DVD 480p going to the tv and being upconverted to 1080i. Try a component feed or try a different progressive scan DVD player of better quality (SONY, Panasonic, Toshiba, Hitachi). If the edge pixelation goes away then the culprit is the DVD player.

How do I let the TV upconvert? I cannot find the settings for these things.

If there are no menu options then it will display at native resolution (1080i) and therefore upconvert any other signal it receives, ie 480i or 480p.

Does it kinda look like the "blocking" that happens sometimes on a digital cable feed? HDMI is still rather new IMO, and I'm sure not all of the bugs are worked out. How about 720p and, like Blue said, letting the set upcovert from that? Did you try the component inputs? I know the DVD player won't upconvert thru them, but it's maybe worth a try. That kinda negates the need for the upcoverting DVD player though. How about a different HDMI cable? Maybe it's just shotty material- you could always get a bad anything. Just a few things to kick around...

As for the picture size, I'm assuming that you have the player set for a 16:9 monitor. It's funny- it's the simplest part but that's the first thing I missed when I first got my set. Other than that, I dunno abut the size problem- maybe the player needs some Enzyte...

Ok, that was bad. Boo me now if you'd like... :o

Yeah, I thought DVDs looked better on a standard non-HDTV. Standard definition and DVDs look horrible on my HDTV in my opinion. HD, however, is god-like.

The player is set to play in 16:9, and it does this, however it does so with the black letterbox bars on the top and bottom. What confuses me is that the picture doesn't seem to be stretched. Whatever.

I will try it with component cable. Thank you to everyone who's given some imput, it has helped. One last thing, however, is there a cheap place I could order from online to get the cables? I bought the monster cable equivilant for my hdmi cable and I don't feel like wasting money on a cable again. I just need one that will work, I don't need gold plated yada yada.

I check Ebay for all my connectors. I got (3) 3' TOSLink cables for $9.92(shipping included). It's the place to go... :D
