I have no intention of bashing LG as you may be feeling. I said in my post earlier also that it's due to the IPS panels that LG TVs have poor blacks and contrast compared to Samsung/Sony. As adder mentioned, even Sony TVs with IPS panels have the same poor blacks and low contrast.
Read these reviews of LG LM9600 (the best LG TV) and you may understand what I'm trying to say. My intention is only to clear some misconceptions about IPS panel that you guys may be having due to LG marketing.
HDTVTest UK Review of LG LM9600
LG 47LM960V Performance
More realistically, the black patch in the middle of an ANSI test chart returned 0.169 cd/m2, 0.148 cd/m2, and 0.158 cd/m2 for the Low, Medium and High local dimming settings, and 0.174 cd/m2 with the feature turned off. Either way, dont get caught up in the small differences although theyre standard for IPS LCD, none of these are particularly impressive blacks.

The ability to produce a deep black is the most important element of any TV's picture. If a TV performs poorly here, its image will look weak and lifeless, lacking what some people call "three-dimensionality." While there have been several TVs with lighter black levels than the LM9600's this year -- LG's own LM6700 and the atrocious Panasonic DT50, for example -- for none has quite so much money been asked.

LG 47LM860V: Full Review
However, the contrast is still a little low, at 970:1 when the best models reach over 4000:1, giving an image that's four times as contrasted!
The main problem is that the black just isn't deep enoughit actually looks a bit grey.3D image quality is almost flawless. In fact, this is one of the best TVs for 3D viewing out there right now. However, the general image calibration could be better and contrast is too low.

LG LM9600 / LM960V review - FlatpanelsHD
LM9600 is a great performer in many areas, but it has some issues that we found hard to abstract from. The most important one is the faulty 1080p24 implementation, which causes the TV to introduce motion blurring when showing Blu-ray movies. The other one is the high level of input lag. The Nano LED technology also worked in a different manner than expected. Instead of relying on a full local dimming system, it only has a few zones and fails to reproduce the same deep black levels as last years LW9800 model.

The sets only real shortcomings are black level and shadow detail. It isnt that theyre unacceptably bad. They arent. But even with LED Local Dimming on High (and youll want to have local dimming onthe blacks are dramatically worse without it), theyre little better than average among todays high-end sets.

LG LM960 (55LM960V) 55 Inch 3D LED LCD TV Review | AVForums.com - UK Online
Despite the 55LM960's striking design, excellent Smart TV features and impressive calibration controls, it let's itself down in two very important areas - black levels and backlight uniformity.
We can't say were were surprised by the black levels because they have never been LG's strong point but they were very poor even for a LCD TV and measured 0.25 cd/m2 in their native form. Due to the poor black levels, shadow detail also suffered, making it difficult to distinguish details in dark scenes.
The difference in black levels between the two was quite shocking and even with the 55LM960's local dimming set to high, the P55VT50 was vastly superior.
As you can see I've picked THE most trusted and respected Television review sites on the Internet and they all say the same thing about LG's flagship TV. Again, the problem is the panel itself. If LG uses VA panel they can make as good a TV as Sony HX950 and they have in the past - LEX8/LHX55 etc are OUTSTANDING TVs. Just that the 2012 lineup is NOT impressive at all.
