LG 42" 42PQ6000 Plasma Motion Blur

Hi everyone,

I have just purchased the above TV and according to LG, the TV is supposed to have zero motion blur due to the 600hz refresh rate.

I tried watching it last night and there is definitely a grainy appearance when watching programs via my SD Sky+ box and football seems particularly poor so I was just wondering whether there is anything that I have done wrong with the setup or if it is just one of those things.

I have a scart lead connecting the tv scart on my sky box to the rgb scart in (scart 1) on the TV. The picture via the TV's built in freeview seems to be better than the feed from Sky and I was just wondering if anyone has any ideas please.

I only really watch sports on TV most of the time so really need to find out whether the picture can be improved or whether I should send the TV back and keep my old CRT for a while longer?

Any advice would be very much appreciated.

Best regards,

Ian

The poorer sky picture could be due to a poor quality scart cable or the settings on the sky box, I can't say how to set them up though as I don't have a sky box. Or even the feed itself, for example setanta and ITV are normally terrible quality, but BBC sport is normally pretty good.

I would let it settle though, the phosphors being particularly harsh in its early life means that it is most prone to phosphor lag, which is probably a lot of what you're seeing, during this time. Get some hours through it and see if you still feel the same. And the 600Hz feature is a sub field, I don't know how it works completely (there are several stories floating around) and it should enhance motion to an extent, but it displays at 100Hz, not 600Hz.

Some of the quality will lie in the settings as well though, I wouldn't know what to change to improve it but keep it out of sport mode! And just because it's new you wont necessarily get a better picture than your CRT, they are still very much the leaders in terms of SD feeds particularly

Hi there,

Thanks very much for the quick reply.

I have been looking around today and from other posts have seen a lot of comments about blur being reduced by customising the settings and reducing teh sharpness to zero so I will have a go at that later to see if this helps. I know the scart lead is decent quality as it's relatively new and I asked for some advice before purchasing it so I'm assuming it must be the settings on the TV.

The main motion blur seemed to be with Match of the Day on BBC1 last night where certain scenes were very 'blocky'. Hopefully I can get the settings changed in time for the Champions League final tomorrow! I'll play around with the settings tonight and see if that helps at all.

Thanks again for the quick response.

It shouldn't be motion blur, at least not entirely, as plasmas handle motion very well and it'll be better than any LCD on the market, at least for similar price (and more). It is more likely to be at least largely phosphor lag, which will settle down a lot over the next couple of hundred hours of its life. On my PG6000 (from last years LG range) I saw a bit of phosphor trailing in the first 200 hours, but I haven't seen any since. I wouldn't rule out your CRT being better though, especially if it's a decent one.

Turning the sharpness down a bit will help a little, whether you need to turn it down to 0 or not I'm not sure, mines on around 30
 
Ok might be a bit of a stupid question, but why don't you watch something like the champions league football or perhaps the French Open Tennis on both the Freeview Tuner and your Sky Feed ... this way you will be able to tell if it is a problem with your Sky set up or not.;)

Edit: See you have done that. As suggested maybe post up your LG Picture Settings for your SKY connection and see if anybody can suggest anything that needs tweaking ... in my experience you will NEVER get as good a picture on a Scart connection as my Humax PVR is pretty soft compared to the inbuilt tuner.

Hi guys,

Thanks for the advice - I did try watching the french open via the BBC red button and the freeview reception did seem better, althought the thick white line along the top fo the net was quite distorted, even when the camera was still, whilst waiting for someone to serve.

I will try a few different settings and run both sky and freeview through it to see if there is a noticeable difference.

I guess in the interests of fixing this problem I'm just going to have to resort to watching as much TV as possible over the next week to clock up a few extra hours and break the set in, it's a tough job but I guess I can force myself to do it!

Cheers again for the help!

Personally I dont even notice motion blur on my PG6000 (the older model), perhaps you mistaken some lack of resolution for motion blur because Scart is really not adviced for HD imaging...

Hi all

I've had my PQ6000 for less than a day but I also noticed the blocky picture straight away. However this is poor sd feed rather than motion blur imo. I've owned cheap lcd tvs and I know how bad motion blur is.

I've played wipeout hd via my ps3 and it defo don't suffer from motion blur.

I've invested money in a good RGB scart lead for my sky box so I'll report back as soon as its fitted.

Have to say I was rather disappointed in the sd picture but found the "game" setting offered the best result so far.

the best results I found when testing came in the expert menus, here you can change everything so you get a very natural image which is very good for SD TV. The quality can also vary hugely if the settings on a sky box or virgin box etc...aren't right, blocky pictures are a symptom of this

There aren't many setting on my sky box, contrast or rgb/pal.
Not had a look at the expert mode yet. What settings are you using?

I only have last years model so the settings would no doubt be different. I have tested the PQ6000 in a local specialist TV shop, I 'helped' towards the end of the calibration process, I can't remember the settings off the top of my head I'm afraid

EDIT: I think it's the RGB settings which make the picture either good or bad on sky, there have been people going from dissapointed to very happy with that change
