I bought a Samsung LE40M87 1080P TV the other day.

The picture quality is fantastic, no dead pixels, no clouding etc, all fine, except for one thing.

When I play a movie on my Xbox 360 (happens on TV too) it struggles with fast moving objects - especially stuff panning across the screen. It's as if they TV can't keep up with the image.

Is this a fault or a 'feature' does anyone know? My 26" Samsung does not have this problem, but I am wondering whether it's the sheer size of this thing (sitting 11 feet away) is the reason I'm noticing it.

Many thanks in advance.
 
i'm assuming this is a plasma and the sammy is LCD? if so that imo is your problem, plasma's ghost high speed moving images, I know the football does when we watch SKY on my dad's.

BTW I know bum all about TV's so could be very wrong

It's a 1080P LCD mate. It's not so much ghosting, it seems to be more jittery than ghosting. It hurts my eyes really, trying to adjust to the image struggling across the screen.

How is it connected?

Component for the Xbox 360 and HDMI for the Virgin Media V+ box. My mate has a 46" Sony Bravia (720P) and sitting the same distance away I don't notice stuff like this on the 360 or the TV. Weird.
 
I haven't had much of a problem with Component, it's odd that you're getting that as a problem from the Xbox360.

Could be your noticing 3:2 pulldown. Film is a measly 24fps, and your tv runs at 60hz, those numbers dont mix :p. Films will either speed up so slightly to 29.9fps, in which case things are still smooth, but the the film is shorter. Or they display some frames twice, which is produces a noticable judder.

I could have explained that completely wrong, and probably have. But it does exist, and it does suck.
Is a problem with all sets not supporting 24p input, and it makes my eyes cry.
 
I don't think that's the prob - he's getting these issues standard dvd and tele.

It happens on both. American films are 24fps, your tv/dvdplayer/whatever will deal with it accordingly, usually by using 3:2 pulldown. TV is generally 30fps in the uk, but american tv again is 24fps.

The “3:2 pulldown” telecine process creates a slight error in the video signal compared to the original film frames that can be seen in the above image. This is one reason why NTSC films viewed on typical home equipment may not appear as smooth as when viewed in a cinema. The phenomenon is particularly apparent during slow, steady camera movements which appear slightly jerky when telecined. This process is commonly referred to as telecine judder. Reversing the 2-3 pulldown telecine is discussed below.

PAL material in which 2:2:2:2:2:2:2:2:2:2:2:3 pulldown has been applied, suffers from a similar lack of smoothness, though this effect is not usually called “telecine judder”. Effectively, every 12th film frame is displayed for the duration of 3 PAL fields (60 milliseconds), whereas the other 11 frames are all displayed for the duration of 2 PAL fields (40 milliseconds). This causes a slight “hiccup” in the video about twice a second.

Thanks for that mate, I am not sure, but you may be right. I noticed it really badly there watching Top Gear, when they tested the Fiat 500. The jitter effect was hellish. I turned my V+ box down from 1080i to 720p output and it seemed to help it. I watched the same source on my Sammy 26" and the same effect was noticeable, but it was a lot less of an issue due to its size.

I also watched DTV on my 40" set and at the standard output of 576 lines or whatever it is from freeview through an aeriel the picture was obviously a lot worse, but it didn't suffer from this effect.

It just seems to be that the TV struggles to move images when so many lines are being shown. As I reduce the quality of the source, it seems to reduce the problem. In saying that, I watched Star Wars on my friends 46" Bravia via the Xbox 360 through component and it looked fantastic with no jitter effect. I don't have the Star Wars disc to check on this, but when I played LOTR through mine on the 360 the jitter effect was terrible. Dunno, I'm confusing myself now :)
 
At my friends house today and played LOTR on his 46" 720P Bravia on the 360 through component. Sitting just 10 feet away and it is perfect. None of this jerky motion I get with my Samsung LE40M87.

If the Samsung isn't faulty, then it is a terrible, terrible TV.
