But, I'd really like to see you make your case for why D55 would be a better reference point white. I don't mind you having a "preference" as long as you can support it by logic and not 'well I just like it better my way.'

The reason is that once you go down that path, you might as well have no standards at all ... and soon thereafter you're in "Audiophile-Land," which is nothing but complete anarchy and super-secret mojo that only shamans with "golden-ears" can decode.

FWIW, I spent the day turning gamut graphs over in my noggin and ultimately I concluded that the only significant outcomes from using D55 instead of D65 would be that the peek brightness of the display would be reduced which would also reduce the on/off contrast ratio. Color rendition would not be affected either way (assuming that every DVD/BD title ever released were remastered/re-encoded based on a D55 whitepoint.)

And to keep this more on topic, I can guarantee if you tried D55 on an xxLK450 you'd lose a bunch of peek brightness. Red is already running on fumes at D65.

This is not *dogma* it's (relatively) simple math and science. 1+1=2 ... 2+2=4, etc, etc. So don't try to make it out as those "stuck up experts keep trying to telling me what's right."

Great then and alrighty! Good to know know all the math works out.

Those that are interested can start a thread in another sub forum.

Everyone have a nice Spring Day!

You asked.

PS: Just make sure that you understand that phrase, (assuming that every DVD/BD title ever released were remastered/re-encoded based on a D55 whitepoint,) is why the whole exercise is academic. If you just arbitrarily set your display to "D55," you would, in fact, introduce a significant red-shift (along with killing your light-output and contrast ratio.)

.... I type these things because a) I'm not sure if you fully understand the science/math, b) you do understand but just want to be contrary, c) don't understand at all, or d) just don't care and want to twist all the knobs to 11. I honestly can't get a valid reading based on your posts.

I'm planning on getting a Sammy D630 I saw at Best Buy as a bedroom TV to complement the larger LK530 I have in the living room. The LK 520/530 series has better overall bright scene picture quality but for black levels the Sammy D630 is hands down superior in that department. I just always longed for a quality CCFL TV with plasma like black levels with adequate shadow detail which will bring more depth and realism into movies with dark scenes or scenes that feature a night sky.

So I thought I'd snag another quality CCFL TV while I can as manufacturers are starting to eliminate CCFL TVs from their lineup and focus strictly on LED LCD TVs. As of a matter of fact, there are no CCFLs in Sony's 2012 lineup nor Sammy's 2012 lineup. I think LG will follow suit either in their 2013 or 2014 lineup.

Yes, the Samsung S-PVA LCD panels have the best black levels of any LCD technology but LG S-IPS panels have wide (horizontal at least) viewing angles and ideal color accuracy not to mention low input lag.

Do you find the Samsung better in any others areas than black level and the related shadow detail? I'm curious.

Well while I think the LG has the edge in color this Samsung d630 TV still produces a very good picture which rival Samsung's higher end LED TVs. The Sammy d630 has everything you can ask for in a TV without all that Smart TV mumble jumble. One other main strong point on this D630 model besides black level is in its picture control settings. It appears to have excellent picture control settings for color management, white balance and/or grayscale which are on par with LG's already excellent picture control settings.

Also the Sammy D630 has plenty of inputs that rival higher end model TVs. I also like that is has user adjustable motion blur and judder settings, wireless DLNA connectivity, and a swivel stand like the LG. So IMO, this D630 has the total package (minus the Smart TV) just like the LK520.

That's good to hear because I love my LD520 that we've had for over a year. Never a problem and once calibrated, the pq has been excellent over a range of sources. Smart TVs are overrated IMO so I just depend on my AppleTV2 and wireless BD player for that.

My d630 is more blurry( overall and defenite more blur with motion)than the lk520 I had.Also the lk520 is brighter and more alive than the d630.i still think overall the d630 is Slightly better.Probably the only reason is the way the blacks look.

4 out of 4 people that have seen both tvs said the lg looked better,clearer.

That makes me even happier about owning the LG (though mine is the 60Hz model).

Fixed!

120Hz is the only difference, get the S-IPS panel though

Is there a way to combat the back light bleeding problem when watching movies in the dark? It shines out the back half of the time when watching any film, and it makes the experience ubearable...My Back Light is currently at 47. Maybe, i could block out the light somehow with something in the back during a film, but that would mean zero ventelation.

Are you positive there is no PQ difference between 60hz and 120hz models? The ones I saw in best buy were noticibly different in PQ but I was comparing a 46 to a 42 since they only had one size of each model displayed

You've asked this question before and I'll give you the same answer as I did last time. One, why are you watching movies in the dark? and two, use a bias light behind your tv for a better viewing experience.

PQ should be the same if the demo sets are setup with comparable settings (which they quite often aren't). What were the noticeable differences?

I never saw your answer, and why would i watch movies in the dark? You can't be serious....lol when you go to the movie theatre do you watch movies with the lights on? I'm a massive horror movie buff, why on earth would i watch 'any' horror movie in the light? Movie experiences for the morst part depending on the genre are 'ment' to be watched with the lights out to that get movie theatre experience.

One reason for NOT watching in the dark is because TVs generally have much higher peak light output at the close distance usually viewed than you see in a movie theater. For example, for your LG, you would probably have to turn the back light down to the 25 to 35 range to approximate the light levels you would experience in a movie theater. And, using a low power) bias light behind the TV helps perceived black level especially on LCD TVs.

If you haven't tried it. . . many people are amazed at the difference. It would also solve your issue.

it looked like one had some noticible artifacting, could of been a setup issue as you mentioned. 120hz seemed much cleaner.

I've decided to buy one of these models before the CS560/570 comes out and was wondering if anyone has any idea what percentage of the production run had the IPS panels. was it early production, or late production? any run patterns? I guess I'm wondering if I order one now what am I more likely to get. If its in this thread somewhere point me to it but I can't read all 70+ pages Thanks!

Prices seem consistant at $500 for 42'' 60hz and $580 for 42'' 120hz. Can I expect a drop, should I wait, or buy now?

IPS panels have a "Y" in the fourth position of the Product Code on a white lable near the model number. Just use the Search Thread on top RIGHT of the thread page here for IPS or S-IPS

And sometmes prices increase on old models as the inventory starts to thin.

I guess what I'm wondering is how difficult are the IPS "Y" code to find in 2012. Is it something they changed halfway through production? Alot of the panel lottery threads seem to be around 2010.

That's really hard to say. There doesn't really seem to be a rhyme or reason to the panel lottery. I think it's got a lot to do with panel availability. At this point in time, you're best bet is to start hitting the local stores and checking out their stock which will probably move fast now that the 2012s are starting to hit the shelves if you want to get a good deal on a 2011. The complete product code is impossible to get out of an online dealer because they'll just grab what they have in stock.

I'm not talking about having all the house lights on. We have all of the lights off except for the bias light (a 5500k 15W CFL) which is behind the tv softly illuminating the wall around the tv and the ceiling with the proper light temperature (or close to it). Proper bias lighting is recommended by the video experts for the optimal viewing experience. It tricks the eye and brain into seeing darker blacks which actually enhances the pq dramatically, and there is ZERO eye strain which a lot of people get after watching tv in the dark with the only illumination coming from the tv panel. And, as Phase and myself alluded too, it will take care of your "light leakage" issue from your set.

Just realized these don't have picture in picture. What comes close that has it.. am I stuck with going with a D550/D630 again? but those have ghosting issues. Thats the only similar TV that I can think of with it.

I know what you mean about the immersiveness, but on a TV like this with a poor black level there is no point to watching it in total darkness since a bias light improves perceived black levels quite a bit.

Bias lighting has the following benefits:

"What are the proven benefits of correctly implemented bias lighting?

1. Reduces or eliminates eye strain and viewing fatigue in dark viewing conditions.
2. Eliminates image contamination due to reflections, haze and glare on the screen from conventional room lighting.

3. Enhances perceived black levels, contrast ratio, and picture detail by enabling dark adapted viewing.

4. Preserves correct color perception of the video image by the viewer.
5. Prolongs monitor phosphor life by enabling dark room viewing and lowering of screen brightness requirements (phosphors are used in CRTs, plasmas, and LCDs with CCF or white LED back lighting).
6. Provides a low level of illumination in the room for movement and peripheral activities."

Unfortunately, ALL these reasons and benefits have been listed before.

doesn't make it any less valid though

I think what Phase meant was that information like this has been given to this particular poster before but he either doesn't see it, or chooses to ignore it.

oh

Plasmapz sorry I was a premature with the brightness as I was able to crank up a few notches the gain controls in white balance on the d630 so its close to the brightness aliveness on lk.You got the clearer picture still.
