If you don't mind the 24p motion interpolation and are happy in the fact that you're not getting top-tier black level performance, then the LG 50PS7000 represents fantastic value for money.

Nice review David.

This telly sounds so close to being the business.
It seems Panny have something to worry about, as they're being caught

Hi David, another excellent review. I have been considering updating my 5th generation Pioneer for some time, and wonder if this is the model with which to do so. Can you please let us know if they advise you as to whether or not they plan to issue a firmware fix for the bug in the 20-point Greyscale system.

Meanwhile, thanks again.

Cheers,

Martin.

I've been communicating with the people in Korea, so yes, they are looking at the problem

Dear David, thank you for your great review

I have a question about the Energy Consumption test. On the review it is written: “ Energy consumption was measured after calibration, with full-screen test patterns. Measurements were taken with Energy Consumption turned off entirely, and also with the "Intelligent Sensor" on "Low" setting.”.

Now the question is: this numbers: “ Energy Saving OFF: 148 - 307 - 392 (watts)” were taken with the Intelligent sensor OFF (and, of course, without any other energy saving option active in the OSD) or with the Intelligent sensor ON?

I’m asking that thing because, when I have compared that numbers with the numbers of the Panasonic P50V10 review of the same test, I was surprised to see a big difference when the 100 IRE pattern was used. Here are the numbers of the P50V10 review: Eco Mode OFF: 85 - 310 - 520 (watts).

392 watts for the LG and 520 watts for the Panasonic in the same situation, looks a big difference to me.

Thank you very much in advance

Hey Althoas: "Energy Saving Off" means "Intelligent Sensor Off", yes. And you're right - there was a big difference in power consumption.

Althotas · 20-06-2009, 7:19 AM

Thank you David.

It would be interesting to know the maximum brightness of the panels, at least when all the energy saving options are OFF. Do you think it could be possible for AVforums to add also that information to the plasma display reviews?

I have an interesting (maybe) "tip" for you

: I'm sure you know there is a "problem" on many TVs regarding the color standard SD or HD, when you are using a DVD/BD player and you are playing a standard DVD at 720p/1080i (using the upscaling). The right color standard, in that case, should be Rec.601 (SD), but from what I know, most of the players are using Rec.709 (HD), which is wrong, and without doing any color conversion.

Now, speaking about the TVs, most of them don't have an option which allow the user to set the right color standard for the HDMI inputs, and so, if you don't have the "right" DVD/BD upscaling player, in the above case the colors displayed are wrong. The LG plasma (PG, PQ and PS series at least) have that option (!), but on my 32PG6000, when I made some test by using my old (but still good) Oppo 971H player, I have discovered that if I set the player at 576p, the "color standard" option of the LG is available, and i can change it from SD to HD to see the differences, but when I set the player to 720p/1080i that option on my 32PG6000 is disabled

and so I usually use the player at 576p, because otherwise the "color standard" option on the PG is HD, and i have wrong colors. Not really a problem in my case, because the processor of the 32PG6000 (Genesis FLI10610H) is doing a great work, and also because the 32PG6000 is only an HD Ready and so, using the player at 576p, there is only 1 video-processing of the input signal. But things are different if the TV is full-HD, like this PS and his bigger brother. In this case, if you have a good player, it is better to check what setup is doing the best work.

Now the question is: do you know if the "color standard" option of the 50PS7000 is enabled or disabled when you are playing a normal DVD at 720p/1080i? If it is disabled (and "HD"), like it happens on my 32PG6000, do you think it could be a good idea to have that option always available and, in case, write to LG about that thing?

Thank you again for you time, and sorry for the long post and for my not-perfect english

Hi David,
Any news on the calibration bug?
Thanks!

David Mackenzie · 22-07-2009, 2:40 PM

Nope, nothing

Althotas: sorry for not replying to your post - I didn't mean to ignore you before!

I'll raise the issue, it's certainly possible.

Yes, this is a great feature request. I will ask them about that.

Hi Guys,

Wondering if you could elaborate - in words of one syllable - what the practical effect of the "24fps problem" is on watching Blue Rays.

Does it mean that effectively, the 1080p 24FPS doesn't work well so you have to set the BR player to normal 60fps ?

Thnx.

Just wondering as the 8000 which doesn't have the problem is £100 more....wondering if I could go with the cheaper 7000.

Thnx in advance.

It means that the TV will take the lower frame rate of film and smooth it out, so occasionally, films can have a bit of a "soap opera"-ish effect amd become unfilmic.

Monarch · 17-08-2009, 3:43 PM

About the frame interpolation on 24p sources did you try turning the film mode off? The reason I say is that film mode on the LG LCD models appears to be the same as 'real cinema' (ie truemotion for movies) which is designed to remove judder, it might be the same here?

David Mackenzie · 17-08-2009, 4:17 PM

Good suggestion, but "Film Mode" is greyed out with Progressive input.

Monarch · 17-08-2009, 4:54 PM

oh yea, just realized it's the same on my PG6000, though it was a long shot

Monarch · 17-08-2009, 11:37 PM

I've also been told by a PS7000 owner on the forum (I told him to pass on the message, not sure if he did) that the greyscale bug only effects the HDMI 1 input. I also remember reading someone else say (on whath hifi or somewhere like that) that their set was effected from 60 IRE and above, but they saw another which wasn't effected...I'm not sure whether I trust them though
