LG 50PK750 Review

Tags: 1080p, 50 inch, LG, PK750

LG is one of the HDTV manufacturers aiming at creating products for all ranges of quality and prices. LG Infinia 50PK750 is only one step lower than its brother from the other Infinia series, LG Infinia 50PK950, but the TruBlack filter already cannot be found on it, which means a decrease in picture quality, as well. On the other hand, this 50 inch plasma TV has solid entertainment options, and, even if there are certain issues concerning image performance, for the price, LG Infinia 50PK750 can be quite a good deal. It is also THX certified, which means its colors are really something to brag about. Obviously lower in terms of quality, when compared with products such as Panasonic TC-P50G20, and the more competitive 3D HDTV models on the market, this LG plasma TV still has its fair share of good points, as we will see further.

Pros:

  • Extensive entertainment options
  • Fairly priced
  • Elegant design

Cons:

  • Black levels not as accurate as on other plasma TVs
  • Image retention issues
  • Problems when displaying 1080p/24 content

Features

Although a little less competitive than LG Infinia 50PK950, LG Infinia 50PK750 has about the same online streaming options and services that make the product quite worth your while, if accessing services like YouTube and Netflix are your thing. Usually, most companies keep the best extras for their flagship models, but, since LG decided to have two series of plasma TVs in their Infinia line, LG Infinia 50PK750 does not disappoint as far as entertainment options are concerned. The Wireless Media Box is also present, which makes connecting other devices with the plasma TV quite an easy job. VUDU and Netflix are the most popular services provided on LG Infinia 50PK750, so, as far as features are concerned, this 50 inch plasma TV is quite a well rounded product.

Design

The sleek look of LG Infinia 50PK750 is quite impressive, since being slim is key for all HDTVs released in 2010. The one sheet of glass design, with no visible edges, makes it interesting and elegant. Even critics agree that the borderless design exhibited by LG on its Infinia series released in 2010 makes them the most good looking HDTVs on the market.

Connectivity

The connectivity options are really great on LG Infinia 50PK750, and nothing is really missing, except, perhaps, for built in Wi-Fi, but, since the more competitive LG Infinia 50PK950 does not have this feature, either, it cannot be held against this LG plasma TV, which does very well in terms of connectivity, provided the price charged. There are four HDMI inputs present, along with two USB ports, one input for PC, two composite video inputs, two component video inputs, one RF for cable or antenna, one digital audio output and an Ethernet jack. If you want to use the model’s wireless capabilities, you will need to buy an extra dongle and attach it to one of the two USB ports.

Picture Quality

Image performance is very important for any plasma TV, and LG Infinia 50PK750, unfortunately, does not really impress. While it is true that the model is THX certified, its black levels are a huge disappointment and drag the model under, marring its overall performance. There are also some issues related to displaying correctly the format in 1080p/24, mainly found on Blu-Ray discs. As consolation, the standard definition performance is quite decent, which cannot be said about other, more pretentious models that can be found on the market, such as Panasonic TC-P50G20, or Samsung PN50C7000.

Black Levels

Blacks are very important when evaluating the value of a plasma TV, and, since usually, LCD TVs are the ones to suffer in this respect, it is quite a surprise – and not a pleasant one – to discover blacks that look so light on a plasma TV model released in 2010. Unfortunately, the low quality of blacks affects image quality as a whole, and the image tends to look less realistic than wished for. On the positive side, it can be said that the manufacturer invested some effort in delivering better blacks than seen on the company’s plasma TV models. The absence of the TruBlack filter – present on LG Infinia 50PK950 – truly makes a difference, and, if you want to see more competitive levels of blacks, you need to go for the superior model. Shadow detail, though, looks quite good on LG Infinia 50PK750, which is a plus, seeing that the blacks are less inky than desired and expected.

Color Accuracy

Color accuracy, luckily, is one of this 50 inch plasma TV’s strong points, and the fact that LG Infinia 50PK750 received the THX certification is a clear proof that something was done right this time around. Most colors look vivid, crisp and realistic, and even skin tones look good on this LG plasma TV. Small issues may be noted, like a green that can get a little too intense, when pictures of vegetation are displayed on the screen. Despite not relying on some great black levels, the color saturation seems to be quite solid, and reliable. Shadows tend to look a little bluish, as well, but, if you are not a critic, you may not notice such slight mishaps.

Video Processing

LG Infinia 50PK750 is full HD, and high definition content is almost always displayed accurately. We say “almost”, because there are some issues with the way the content in 1080p/24 format is displayed. It is not something LG Infinia 50PK750 can boast about, but the fact that it does not sport a special mode for such content may be the main reason why image artifacts are quite common when you want to watch movies in their natural cadence. Tests show that this plasma does even worse than some 240Hz LCD TVs, which is not something to be taken lightly, since plasma TVs are usually supposed to be better than their LCD TV counterparts.

Uniformity

While many 2010 models no longer experience uniformity issues, unfortunately, LG Infinia 50PK750 is not one of them. It does experience image retention, and burn in effects, exactly like its brother, LG Infinia 50PK950; if you do not want to confront with such problems, it would be a better idea if you would go for the Panasonic TC-P50G20 model, or Samsung PN50C6500. The traces disappear after a short while, however, which means that image retention is not such a big problem; yet, the fact that it does exist may influence your decision when you want to buy a new plasma TV.

Anti-Glare Performance

The borderless design is what brings a lot of problems for LG Infinia 50PK750. While it looks extremely dashing and elegant, the glare problems that result are not to be taken lightly. In short, you will not be able to watch your television shows, or anything else you like, on this 50 inch plasma TV, without having to experience glare and reflections. The colors and the blacks are also affected, and they tend to look more washed out than you would like.

Standard Definition Quality

Luckily, LG Infinia 50PK750 does quite well in terms of standard definition performance. For instance, DVD sources are handled well, and even regular broadcasting is not marred by visual artifacts. Noise reduction capabilities are great, indeed, and jaggies are kept to a minimum, which cannot be said by many other models released by the competition in 2010. The image delivered is quite sharp, and, while this LG plasma TV may not be the best model seen this year, it seems to have its good points, and standard definition is one of them.

Conclusion

LG Infinia 50PK750 is a product that comes with a fair price attached to it. For the price, image quality is not the best, but it is still good, despite some issues that cannot be overlooked that easily. It does a little worse than its brother, LG Infinia 50PK950, because it does not come equipped with the TruBlack filter, but, otherwise, its colors are THX certified, and the entertainment options are really good, not exactly something to be found on products that are priced under their market value.
