LCD television question...

[Cordy_Biddle]

I just got a Soniq 66cm LCD television for my bedroom, and I really love it, but there's one small niggling problem.

There's a slight picture jitter, especially evidenced during moving or "tracking" shots. It's there when you watch a DVD and when you watch television, so it's definitely not my DVD player or video machine.

Does anyone have advice on what could be causing this picture jitter and how I could eliminate it?

What type of connections are you using for your DVD player? (composite, s-video, component, DVI, HDMI?)

Are you using a cable or satellite box for TV, or just a cable directly into the TV?

[Cordy_Biddle]

For my DVD player/s, I'm using the yellow & white cords. When I play NTSC discs, the jitter is much more pronounced (the TV is primarily PAL but can reproduce NTSC colour system)

Is this NTSC jitter something I can eliminate with another connection device?

You're just seeing 3:2 pulldown. its how they get 24fps (film) to fit into 30fps (NTSC format) by duplicating frames.

Note: PAL doesn't have 3:2 pulldown as they simply speed up the 24fps film to PAL's 25fps. This results in "PAL Speedup" on all material shot on film, which results in higher-pitched audio.

New Blu-ray players can eliminate this by sending the image at 24fps (the same on film in a cinema). However, only recent and often more expensive displays are capable of showing 24fps images.

That comment really doesn't make sense to me, because my brother has a smaller LCD monitor which exhibits absolutely no signs of 3:2 pulldown.

Is there another connection I can buy which will help stop the problem?

You can get component or HDMI cables depending on what your DVD player can use. Either one will give you a better picture than the standard yellow, white, and red composite cables.

I don't think it will fix the jittering problem though. That really sounds like a PAL to NTSC issue. I'm not very familiar with PAL to NTSC or NTSC to PAL, but a lot of it depends on the player and the TV on how good it will do the conversion.

It is the reason. All NTSC content has jitter unless you can switch your player and display to 24fps. There's no other way of getting 24 frames into 30 frames each second. That;s also why enthusiasts on both sides of the Atlantic expect 24fps compatiability on high-end equipment. If it wasn't required, nobody would do it.

Perhaps your new display has a faster response time on the crystals, which is making the jitter more noticable?

My TV repairman has recommended that I buy a set of composite leads (blue and green ones); because he believes my existing cords set-up is part of the problem.

The picture jitter is also apparent (to a lesser degree) in PAL as well; as evidenced when I watched my Region 4 disc of "Gigi" last night. My repairman also noted that the yellow cord connection from the DVD player was extremely loose.

Does anyone have any more advice?

The new component cables (red/blue/green for video, red/white for audio) will provide you with a better picture than your current composite ones (red/white/yellow). I'm not sure if it will resolve the jitter problem though.

Keep us updated. Hopefully the cables help out.

[Cordy_Biddle]

Yes, hopefully they will. If the jitter remains, I'll just have to get used to it. Watched two of my R1 discs this afternoon ("Fathom" and "Modesty Blaise") and the jitter wasn't too obtrusive.

Tonight I ordered two more box sets from Amazon ("The Fly" Collection and the Frankie & Annette movie legends collection), so you see my habit for importing movies isn't being dampened by the frustration of the problem I'm experiencing.

It's just amusing that I could get a perfect, jitter-free playback for my NTSC discs on my old 34cm square telly.

[Cordy_Biddle]

Well, my problem appears to be solved. A second TV technician (who actually knew what he was talking about) has just hooked up my composite cords, making sure my DVD player was in progressive scan mode, and also hooked up my other devices.

The NTSC jitter problem is gone, and the picture quality via my new output is much better. Colours appear a little subdued, but I'm going to play around with colour and contrast settings later tonight.

Thanks to everyone who replied to my post!

I'm glad the cables worked out for you. Congrats on the new TV.

And a big "thank you" to DarthPrime and 2099net. You were very kind and supportive with your posts.

Have a great day!
