So I'm in the market for a new tv but really need some help and advice. So I've been doing alot of research for the past week or so and just need some opinions.

So if I'm correct it seems like there are no full array local dimming LED tv's for 2010. Is this correct? And it seems like Samsung and LG might be the only two companies to offer edge lit LED tv's with some sort of local dimming technology.

My question is which full array local dimming tv's are the best availalbe. Or which were best from last year since I don't think they exist as 2010 models. And now for the important part. Which sets look better, the best full array local dimming tv or the best edge lit local dimming from this year. I would rather give up some size to get the best picture possible.

from your questions it seems you havnt really done much reading on your end either.. xP

the most complimented local dim sets would include the LG LH90, LE8500, Vizio's XVT series, and i need to go check again but i think there's a couple from Samsung too, the B8500 if i remember correctly.
i'm not sure which ones are "2010" or "2009"..i know the LE8500 is the successor of the LH90, and Vizio is just about to launch their new XVT3 series too, within the month or so..so that could be your "2010" option to consider.

and yeah, in general overall, these noted sets still perform better than any edge-lit available even today..giving you the inkiest blacks, color accuracy, "pop", uniformity, etc..when it comes to lcd.

just search around avs, you'll pretty much find all your answers and more ^^

This years TOP local dimming would be the Sony XBR HX909 , no Samsung local dimming this year.

Here is a Local Dimming list link 1 & link 2.

I saw the LG 9500 9 (backlit LED local dimming) today at Magnolia and almost wet my pants at the picture quality. It was in a very dark room and I saw no sign of blooming, or clouding. There was also a pioneer 110 panel in the room and in THX mode, the panel was very close to the pioneer.

Who's your daddy?

I picked up a LG 55LE8500 (full array local dimming) a few weeks back and I continue to be impressed with the PQ on it with everything I've thrown at it. I've yet to see much in the way of any banding issues, though what little I've seen has gone away a bit with the calibration settings I've put on it from the CNET settings.

LG 55LHX or 55LH90 would be lesser cost options to look at from the "last year's" model line.

I'd love a Sony HX909 or LG LX9500, though the price difference between it and the LG LE8500 for me wasn't something I could swallow and I didn't want 3D at this time.

Hello David,
Yes I think local dimming are the best; I was blessed to get a Samsung UN55B8500 a few months ago, it is without a doubt the mother of all full array local dimming monsters from last year, and still a highly sought after set today, although they are hard to find and now selling for almost $6K on Amazon (we paid half that). The level of detail on Blu-Ray movies like Transformers 2 is amazing. I have never seen another TV as brilliant, colorful, sharp and clear; the bottomless blacks contrasting against lighter areas is stunning; especially on lightning, explosions and fire. Basically, what this means is; when we are watching the Matrix on Blu-Ray, and Trinity does a back flip off her motorcycle and sets off a huge azz fireball in our living room, we love it!

Unfortunately there is not locally dimmed set bigger than 55".
Toshiba announced 65" set at the CES but it has not materialized. Moreover it would cost a fortune.

Wrong thread for intitial comment, woops!

On the local dimming front, I saw a great demo of an LE8500 against several edge lit sammy's and the black level and uniformity was clearly superior on the LG.

For the best bang for the buck, go with the LG LE8500/LX9500 and buy some blackout shades for the room. The Sony HX909 might be a contender if only Sony didn't want a small fortune for it. There are no other models from the last year or this year that compare with these TVs in terms of their features, design aesthetic as well as pure PQ. I'd recommend the LG LE8500 as the best value if you don't need 3D, or else go with the LG LX9500 for 3D.

I have yet to find a definitive answer on the 55LX9500 vs. 55LE8500 for 2D. Are these sets exactly the same for 2D, same local dimming configuration (# and size of zones etc.) and such? Or is there some 2D advantage to the 9500? I did notice the 480 vs. 240 motion blur diff, but that may just be gimmicky.

Cheers!

The 9500 has a scanning backlight to double the refresh rate from 240 to 480. Scanning backlight + 3D = $1500 price difference. If you're interested in 3D than maybe it's worth the price increase.

Thanks, Andrew! I have a haiku: "3D? Not for me.".

Now street-wise I think the diff is more like $900-1000. Which is still a lot of dough . Sounds like there's some hardware sophistication behind the motion blur feature. So the big question is, for 2D is the scanning backlight a visible plus? Probably not $1K's worth ...

Would the scanning backlight make image more uniform in dark scenes? I saw the 9500 at magnolia next to a Pioneer pro110 and couldn't believe how similar the picture quality was, even in black level. If the 8500 truly has the same image as the 9500 minus 3D, then Samsung and Sony should be very worried.

Who's your daddy?

The HX909 also has a scanning backlight. The scanning backlight does not increase the refresh rate. It increases the perception of response time of the pixrels.

Those who think they know everything annoy those of us who do.
