Review – LG 43 inch smart tv UHD HDR Smart TV

The best LG 43 inch smart tv High Dynamic Range or commonly known. As well as, HDR was the biggest thing in televisions that came for the year 2023.

After all, 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 series of UHD Smart TV.

The LG series of UHD Smart TV features almost all of LG’s latest technology except. After all, 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.

The LG UJ670V features one of the classiest and elegant designs that we have seen on a LG 43 inch smart 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 43 inch smart tv UJ670V display clear and crisp picture with brilliant levels of detail. The bright vivid color 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 color saturation.

Furthermore, the IPS panel is capable of displaying a wider color palette with a deeper level of color and higher color accuracy.

One more feature that drastically affects the overall picture quality is its local dimming feature or as LG calls it, ULTRA Luminance. 

After all, 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 LG 43 inch smart tv, feeding it with native 4K movie or video source will even make the picture quality better.

After all, 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. After all, 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.

LG SN5 2.1 Wireless Sound Bar

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

  • Original branded product
  • Two years warranty for factory defects
