Picture Quality

In terms of picture quality, the LG 43UJ750V is a decent performing 4K TV which is to be expected from a TV that has a 4K resolution, IPS display, and HDR support. Although, the quality is not on par when compared to SUHD or OLED TV.

With the support of HDR 10, HLG, and Dolby Vision. The picture reproduction is clearly bright and colourful with a definitive clearness. To really enjoy the vividness and natural colours, we highly suggest to turn on HDR at all times.

In terms of contrast, whites are brighter and blacks are deeper and darker. Thanks to LG’s Ultra Luminance Technology that lifts the brightest scenes and the darkest shadows to life.

The upscaling is working great and can further enhance low-resolution videos but of course, don’t expect miracles.


The LG 43UJ750V is basically not an ideal gaming TV. Performance wise it’s okay if you’re not going to complain about its 50Hz refresh rate. Though for someone who knows his stuff when playing video games, it’s definitely a bummer to the standard 60Hz that you can find on other TV with similar specification and pricing.

On the other hand, if you’re okay with a 50Hz refresh rate that can only do 50 frames per second, then this will be a decent gaming TV because of its picture reproduction performance. The colour of every image will be above satisfactory paired with a wide range of gamma and deep level of contrast.


In terms of audio quality, the LG 43UJ750V sports two built-in speakers that use 20 W of power. The audio is decent and not disappointing in any way given that you’re not expecting much from it. Otherwise, if you want an audio with a really good punch, then we highly recommend pairing this TV with a soundbar from Sonos Sound.

Other than that, it is also a plus for us that LG equipped this TV with LG sound sync, the DTS decoder and the Hi-Fi audio support.

Our Verdict

2017 is probably the year of HDR for 4K TV’s and the LG 43UJ750V is a proof of that. What amazes us with this model is that it already supports HDR10 which is a 10-bit colour depth for HDR contents that is also paired with LG’s Ultra Luminance technology giving an amazing picture and colour reproduction despite being just 43-inch in size and having a very affordable price.


  • Affordable TV with HDR10
  • IPS and Ultra Luminance
  • webOS 3.5


  • Poor Gaming Performance (Input Lag Latency)
  • 50Hz Refresh Rate
  • Average Audio Quality

Lastly, this is not a TV for gamers. It has a disappointing native refresh rate of 50Hz only and a poor input lag latency. But, if you won’t be using this TV for gaming, then this is a great choice for TV.
