LG 42LK450 review


A simple HD TV at a good price

The new LG 42LK450 is a simple little TV with a good price. Sure, it doesn’t have that many features when compared to other models, but that’s not really a problem if all you want is a device that works well and suits every room you put it in. And now for our test and review.

Good features

This LCD TV comes with specifications such as: 42″ screen size, 1920 x 1080p resolution, 40.1″ x 24.8″ x 3.0″ (without stand) / 40.1″ x 27.5″ x 10.4″ (with stand), 13kg (without stand) / 15 kg (with stand), 60Hz frame rate, XD Engine, 16:9 aspect ratio, 10W + 10W 1-way dual speakers, Dolby Digital Decoder, Infinite Surround, Clear Voice II, auto volume leveler, 1080p source input (HDMI / Component / RGB), 3 HDMI, 1 USB 2.0, 1 optical audio out, 2 AV in, 2 component in, 1 PC in (D-Sub 15 pin), 1 headphone out, 1RS-232C, 1 RF, AV input navigation, VESA compatible (200mm x 200mm) and 2 AAA batteries required.

Simple design

LG-42LK450LG 42LK450 offers the following features: Intelligent Sensor, Picture Wizard II, Smart Energy Saving (Energy Star Qualified), bass, treble, balance, auto volume leveler, sound modes (5: Standard, Music, Cinema, Game, Sports), Picture modes (8: Intelligent Sensor, Vivid, Standard, Cinema, Sport, Game, isf Expert 1 and isf Expert 2), auto tuning, channel add, favorite channel, clock, timer, sleep timer, auto off, child lock, closed caption, Simplink, a remote control and a manual.
The design is simple: there’s a black framing bezel made of plastic and one power button which is actually a touch-sensitive area very easy to turn on. The 42LK450 model is really slim, so the touch-sensitive power option is a good idea if you want to keep the device steady on its feet. The screen is antiglare, a fact that is really nice if you sit in a brightly lit room. The viewing angle encounters the same problem as with other LG TVs: contrast starts to degrade at around 30 degrees off center.

Two menus

The device comes with two menus: a quick one and a complex one; the latter features all kinds of controls, which greatly reduce the need to constantly jump through a lot of options just to delete a channel, for example. But when we wanted to change channels, we noticed that this was a slower operation than the one we performed on a PC featuring an USB tuner.

Picture Wizard II technology

Via the Picture Wizard II this TV self-calibrates image quality with on-screen reference points; elements such as tint, color, sharpness, black level and so on are thus easily adjustable to ensure a great viewing experience. Moreover, the Intelligent Sensor feature automatically adjusts the picture on the screen by analyzing the lighting and color in the user’s room. The newest LG 42LK450 also sports the 1080p option; via progressive screen, the latter doesn’t let images interlace. Also, this TV is able to display 1080p horizontal lines of vertical resolution, with good results obtained for this review. All of these assure good image quality: there are no image lags, colors are crisp and not oversaturated, text is clear and everything looks bright and natural.

The sound quality is not so good

The sound didn’t blow us away when we tested the 42LK450 TV, because the built-in speakers aren’t very strong volume-wise. On the other hand, playing videos on this device works really well; we were extremely pleased with the fact that it kept track of where we stopped a video after we watched it.
The VGA port doesn’t handle full HD resolution and the product doesn’t feature the Smart TV functionality for Internet TV; but it makes up: LG have introduced a ST600 Smart TV upgrader with which you will receive all of LG’s Internet TV features.
Another big plus for this device is the fact that you can connect older DVD players to it via a component video input.
Finally, the Smart Energy Saving feature means that the TV will consume less energy than standard HDTVs.

Review conclusions

And here is where our test and review ends. The new LG 42LK450 is a great option for those of you who prefer non-assuming LCD TVs at good prices. This model offers good quality entertainment and is easy to use.
