The LG LHX series is an ultra-thin LED HDTV and the latest in the family is the 55LHX.  This 55" LED HDTV sports a wireless transmission media box that can send an uncompressed 1080p signal to the TV from up to 30 feet away. 

55LHX has a 55-inch LCD screen. It is only 0.98" thick, and features an improved LED backlight system.  Users can be assured of minimal wiring, as most media devices can be connected wirelessly due to the wireless transmission media box that is integrated within this system. This also makes wall mounting an easier option. Users will only see a single cable for the power connector and another for HDMI connection. Without the stand weight, it weighs only 57.3lbs, while the stand adds another 18lbs.

This model carries the same type of design as other LG LED TVs. It is surrounded by a glossy, black frame and the TV controls are on the lower right corner.  These are illuminated with a bright, blue light. The buttons may confuse some users as their functions are labelled with symbols rather than text. They are a bit awkward too, as they are touch sensitive and embedded into the frame of the television. Its stand is a flat, rectangular piece that is connected to the TV with an arched swivel. There is also a separate media box, which makes connections easier to reach than the back of the television panel.

There is only one HDMI port and a power input on the television itself. The remaining ports and inputs are located on the media box. There are HDMI and USB ports at the front of the media box, and many other connection ports at the back. The available ports include two component video inputs, two composite video inputs, 3 HDMI inputs and one HDMI output, a PCI input, a 3.5mm audio input for PC audio, a digital audio output, and an antenna input for receiving either analog or digital signal. The media box has its own power input and is turned on or off with the switch located at the back of the box.

Setting up the LG 55LHX
LG is one step ahead with an integrated wireless transmission media box.  Basically, users only need to plug in the power cord for the television unit that either stands on a flat surface or alternatively wall mounted. Meanwhile, all other cabling and wiring are done at the media box.

The “picture wizard” employs a series of onscreen test patterns to ease user calibration for picture adjustments. Users may calibrate for key picture quality elements such as black level, color, tint, sharpness and backlight levels. It is also ISFccc Ready for professional calibration.

There are too many “features” that LG offers on the 55LHX. Not all features will be mentioned in this section.
The LG 55LHX has a 5 million:1 LED Mega Contrast, delivering amazing clarity and color detail. It also has an intelligent sensor that automatically optimizes the picture to the lighting conditions in the room for a personalized and enjoyable viewing experience.

The wireless technology is simply called Wireless HD. It receives signals from wireless transmission media box. This feature makes the design more attractive as there is absolutely no clutter of wires and cables except for the power cable and HDMI connector. It sends an uncompressed 1080p signal to the TV from up to 30 feet away.

The full HD 1080p set features TruMotion 240Hz, and a Super-In Plane Switching (S-IPS) LCD panel structure with faster response time, improved colors and viewing angles.

Another feature worth mention is the support for 24p Real Cinema mode. This feature is present on many LG models, and it give images a film-like look by simulating the 24 frames per second frame rate accustomed to cinema.

The LED TV has an aspect ratio of 16:9, and a screen resolution of 1920 x 1080 based on the 1080p format support. This TV has a contrast of 5 mil:1 and the refresh rate of 240Hz makes motion excellent with smooth, unnoticeable transitions. This is especially attractive for sports programming and gaming, although not so much for film-based content. Meanwhile, the uncompressed HD 1080p signal is transmitted via the media box using a 60 GHz frequency, with no reported loss of quality and no interference.

Colors remain strong for this LG tv, even at a 45-degree angle. The backlight is broken into 240 individual sections for more detailed control over picture quality, a brighter image and a wider color gamut. However, the image does not look nearly as bright if users view it from the side. Also, there is no special color mode on this television.

There are 3 AV modes preset to optimize picture and sound setting based on Cinema, Sports or Game.

LG included the Invisible Speakers and Clear Voice II features to complete the audio of this system. The Invisible Speakers are amazing and users cannot tell where the speakers are located. No, they are unlike conventional LED TV speakers that are at the bottom of the panel. The Invisible Speakers are concealed within the frame of the tv. Yet, their placement does not disfigure the smooth design of the television. Meanwhile, Clear Voice II is an automatic dialog enhancer.

Pros and Cons
Although this set is aesthetically near perfect, there are two separate units to this one purchase, the TV and the media box. Set up is relatively simple, yet this model is only available as a 55”.

The TruMotion 240Hz actually is effective for gaming and sports programming, but it is not meant for film-based content.

The real selling point of this unit is its wireless capability which clears all dangling cables and wires from the main television unit. There are conflicts over the contrast ratio, with 2 milion:1 for units marketed in US, and 5 million:1 for those marketed in Korea. The Korean set has an unparalleled quality. For what it can offer, this LED HDTV does not come cheap at all.

    I read so many bad news about LG with some other models, so I’m a little cautious when my wife comes back with this guy in his van tailing behind her, and then carrying an LG HDTV into the house. But when I tried it out, it was great.

    It has a media box that connects wirelessly to the tv, so TV looks clean after we mounted it on the wall. Picture is sharp and bright, and it has local dimming too. I like it very much. Now I’m just off-guard against LG. Are they really that bad on other models? This one seems just perfect.

    I got this because it is wireless. I have wireless for almost everything at home, including wireless phones, wireless internet, wireless headsets.

    Hahaha… I’m imagining the user above has a lot of radio waves at home with all the wireless stuff going around. But yeah, I got this because of the wireless thing too.

    The 240Hz is bad for movies, but good for sports. I turn it off whenever I’m not watching sports.

    No complains with this one. I got it and the picture is great. The only thing is maybe the fact that it’s heavy and I had to get help mounting this. But otherwise, the screws for wall mounting was already on the tv, eases a lot of work. No need for dangling wires too, because it’s wireless. The media box works fine. And I was watching Batman with it, the blacks are superb and details are strong. No surprise, it’s got a contrast ratio of 5million:1.

    The media box stopped transmitting my PS3 very dissatisfied.
    I want to love the tv but the wireless media box is killing me. I have tried everything. The LG people cannot provide a reasonable explanation either.
