LG 43UF6400 vs 43UJ6300 – what is the best solution for you?

LG 43UF6400 vs LG 43UJ6300

I had a chance to test and compare two solutions from LG – LG 43UF6400 vs 43UJ6300. 43UF6400 is from the UF6400 series and 43UJ6300 belongs to the UJ630 series. These series also include other high-performance, reliable models.

The 43UF6400 is a 2015 year model, while 43UJ6300 was released in 2017. However, both models belong to the mid-low price range, since they cost around $300. Nevertheless, they have many useful functions. These two models have IPS displays and they use the same backlight technology – Direct LED.
