Samsung 1080p Quirks (component & Hdmi)

[Arc1503559859]

Hey guys, I've got a Samsung M81 46" LCD TV which I've had for a while, I'm pretty sure these things have been happening for probably the entire life of the unit but I only just recently noticed them when I decided to crank the brightness up a bit.

Basically, whenever I'm watching any content in 1080p via component, I see a sort of grid on black, or very low light screens. It only seems to happen when I'm displaying stuff in 1080p on component though, in 1080i, or 720p it just doesn't appear.

This is 1080p component;

This is 720p component;

So yeah, that's my first query, if anyone knows why that might be happening, or how I can get rid of it that would be dandy. The other quirk I'm having is when displaying content in 1080p but via HDMI, I'm not sure what exactly the precursors for it are, as sometimes I see it in low light/dark screens, and sometimes I don't, but basically I get a trailing/afterimage type effect.

This is 1080p via HDMI;

You'll see in the top image the flower has a shadow type thing, because when it came on screen it came from the left, so it sort of cut an image across leaving somewhat of a trail, whereas in the component image this effect doesn't occur.. sorry for the poor explanation but the images should convey what I mean.

I came across a similar type of problem to this once before and after a little googling I found that the culprit was that I'd left one of the image enhancing things on, I think it was DNIe or something to that effect, but I've tried turning off and on all the different options but nothing seems to get rid of it.

Ultimately if I'm stuck with both of these things it's not too much of an issue, it's only a few occasions that I see these things pop up, or in a few specific games due to their lighting, but if it's something that's totally out of the ordinary I will get it looked at

Anyway, any help would be greatly appreciated!

Cheers

Ben

edit: sorry the image tags/code don't seem to be working so I've changed them to links.

To start, for some reason inline images aren't allowed. You're best to just paste the links in and the board will create clickable links automatically. I don't understand why personally.

What's the source? Are both issues using the same source? It would appear to be either PS3 or an XBOX 360.

A lot of TVs won't accept 1080p via component. Perhaps the first problem is simply that it "works but doesn't work properly and thus isn't supported". Looking at the manual 1080p on component is listed though.

For your second problem do you have all image processing turned off? "Movie Plus" was one that people wanted off. There were issues where the TV wouldn't remember the setting which required a firmware upgrade to fix it.

It's likely that the TV will remember settings per source so if you've turned it off on the component input you'll also need to turn it off on the HDMI input.

Personally, I'd stick with the HDMI which solves your first problem...

Ah, not to worry about the images then, they're clickable now so that should suffice

As for the sources, I haven't used the same source to display both issues (the first two images are Xbox 360, the second two are PS3) but the issues do persist across multiple sources.

The component issue that I've shown with the Xbox 360, also became apparent when I plugged my PS3 in via component, though you can't really see it in the snap I took as it isn't dark enough to bring it up.

The HDMI issue I've noted a few times when using my HD-DVD player which I've also got connected to the TV, but via a different HDMI input altogether.. so I'm fairly certain it's not any one source that is disagreeing with my TV but just something that seems to appear across the board (when the circumstances are right, ie 1080p in HDMI or component - coupled with dark enough scenes/images).

And yeah I've had a fiddle with with all image processing options I can find, I've also double checked the movie plus isn't causing it but made a point to get my firmware upgraded shortly after I purchased the TV to make sure that wouldn't be a problem for me. I don't think you can enable it when display 1080p though anyway.

I'll keep having a fiddle but I appreciate the thoughts so far! I'll report back if I have any success.

If you setup the TV as "Just Scan" it disables that stupid movie-plus mode which ensures you don't get the bug... on that input. You need to feed it with 1080 over HDMI to support Just Scan though. I got a technician out to upgrade my M series to fix the "movie-plus shows it is disabled in the menu, but you can clearly see it is still on" bug anyway, as I use the component/svideo inputs also for my Topfield SD STB.

Almost had forgotten about this thread, shortly after I purchased my TV I got a technician to come out and install the latest firmware to get rid of the annoying movie plus bug, and make sure to subsequently turn off movie plus on every input. I find it just looks weird for watching TV/Movie content, if it worked perfectly though I would use it all the time for playing 30fps video games, but it isn't perfect so I stick with it turned off so everything looks more consistent.

Anyway, I've still got both these things happening so just thought I'd bump up and see if anyone else knew what might be causing this. I'm guessing for the component grid type issue it's probably that 1080p over component isn't supported that well with this particular TV but the HDMI thing still perplexes me..

Even if they're not fixable and common across this type of TV at least it's not too in your face I guess!

Eww, that image of the flower thingy on HDMI looks wrong. I think something is broken if that screen is meant to be a homogenous blue colour. I notice a tiny bit of posterization (sorry for the spelling... I think you will get more hits in google with the yank spelling) and/or poor colour stepping in some scenes on mine (e.g. the TenHD promo "I can see clearly now"... with the blueish background where they spin the volume knob thingy, it is a blue background that goes from one shade of blue to another), but not sure if it is the broadcaster compression or a TV artifact (I should watch some more blurays, these won't be megacompressed one would hope! It isn't always evident though, so unless I can watch the same show on FTA and BR, it is difficult to compare if the artifact is broadcaster or TV). I also get another strange artifact, maybe related to posterization in dark areas of the screen, and that is like a "buzzing haze of similar colours". It is never in the foreground of anything, and only in the background, I noticed it a lot in Supernatural on wood colours on, e.g. doors behind the actors. It is hard to say, as when I pause the PVR, the buzzing haze pauses too, so it appears to be yet again a broadcaster artifact. Maybe because I have both the dynamic contrast and the black level adjustment enabled, it is dragging some of this "not meant to be seen" junk out of the noise a bit?
