Review – LG 43UJ670V 43-inch UHD HDR Smart TV

High Dynamic Range or commonly known as HDR was the biggest thing in televisions that came for the year 2017. During the first quarter of the same year, HDR was initially offered to high-end televisions only and that really cost a hefty price for them, consumers. Fortunately, big brands started releasing affordable UHD Smart TV that features HDR. An example of that is the LG Uj670V series of UHD Smart TV.

The UJ670V series of UHD Smart TV features almost all of LG’s latest technology except for those that are high-end exclusive such as OLED display panel, Nano Cell Technology, Harman Kardon Audio, and ColourPrime Technology. However, this specific model still packs some features that are still desirable to have.

  • IPS Display Panel (178° Viewing Angle)
  • 13 ms Input Lag (Game Mode)
  • 60 Hz Refresh Rate

The LG UJ670V features one of the classiest and elegant designs that we have seen on a TV. The body frame is very thin with dimensions measuring 97.4 by 57.1 by 7.9 cm without a stand.

The almost bezeless design makes the TV look more elegant. It definitely adds up to its overall aesthetics.

The edges of the panel that acts as the frame of the display are made of aluminium with a brush-like metallic accent.

The overall design is definitely appealing. However, with the stand attached, we can see some slight wobbling when you touch the TV or just by plugging in a USB to play a movie.

This TV features a 20 by 20 cm VESA mounting standard. The back part of the TV is made of plastic but it doesn’t feel cheap. The I/O connectivity is also located in the back part of the TV. However, we find that the position of the I/O ports is not cable management friendly.

Picture Quality

Once fired up, the LG UJ670V display clear and crisp picture with brilliant levels of detail. The bright vivid colour palette in standard definition is outstanding and the picture quality comes to life when a dedicated Ultra HD source is played through.

The IPS panel means the set has a very wide viewing angle of up to 178° without causing colour saturation. Furthermore, IPS panel is capable of displaying wider colour palette with a deeper level of colour and higher colour accuracy.

One more feature that drastically affects the overall picture quality is its local dimming feature or as LG calls it, ULTRA Luminance. ULTRA Luminance basically enhances contrast. Enabling the TV to express darkness with its distinct contrast between dark and light, producing an image as sharp and clear as real life.

To further enjoy this TV, feeding it with native 4K movie or video source will even make the picture quality better. Using a Full HD source also works but don’t expect to have the same quality if you feed it with source or movies with less than 1080p or Full HD resolution. Don’t expect miracles from that.

Audio Quality

This TV features a built-in 20W 2.0 CH Speakers which is now a standard feature to have. Loudness wise, the audio is okay and decent. It gets the job done but don’t expect a strong loudness from the speakers. Despite hitting maximum volume, you will notice that the speakers lack some punch. On smaller room, the speakers might make of decent but in bigger rooms, the speakers will struggle to satisfy your audio quality demand.

It’s better to pair this TV with a much stronger and powerful soundbar like the LG SJ2 Soundbar.

The LG SJ2 Soundbar features a 2.1 CH speaker system with a very powerful speaker that uses 160W of power.



Gaming wise, the LG UJ670V series of UHD HDR Smart TV is one of the ideal displays to have for console gaming. With its native refresh rate of 60 Hz, you can surely enjoy a smooth gaming experience that allows you to play any games at 60 frames per second. As long as your console and game of choice allow you to.

One of the most important things to know when it comes to video gaming is the displays input lag rating. Input lag is the delay of action that your TV will display after pressing a button or moving your character. The lower the input lag rating, the better and ideal it is for gaming. With the UJ670V, hardcore players will appreciate this TV with its very low input lag of 13ms when in game mode. That’s almost as good as any dedicated PC monitor.

Though setting it on other modes will result in higher input lag of 60ms+.

Our Verdict

The LG UJ670V is definitely an amazing UHD HDR Smart TV but not the best. Despite lacking some desirable features, it still packs a number of features that will make most TV enthusiasts appreciate this model from LG. Given that this TV is a 2017 model, its price will surely drop in 2018. It’s current pricing on Amazon UK is very seducing that you will think twice if it’s legit or not.
