Picture quality

LG UJ6300 4K UHD TV - Hands On Review

The LG UJ6300 LED smart TV has an average picture quality performance. When the TV is watched in the darkroom the image that appears is very disappointing, the black Images tend to look gray. And it has a very low contrast ratio so the picture won’t get much brighter and also has low black uniformity.

These two aspects of the image quality are slightly less problematic if placed in a bright room, as the ambient light can reduce the effect of the low contrast ratio.

Even then, if the light is still too bright, the lower-average brightness may not be enough to fight glare. The gray uniformity might be better, but fortunately, the clean display effect is not too problematic and paired with the passable viewing angle quality, the LG UJ6300 could be used in a wide living room to watch sports with a wide group of people.

Finally, the quality of the HDR might be better This can’t produce saturated colors, it has an acceptable HDR peak brightness, and it also needs local dimming so it doesn’t stand out from HDR content.

Movies – This model is Subpar option for watching movies in a dark room. The LG UJ6300’s blacks are not very deep and lack uniformity, causing black letterboxes and darker scenes to often look blotchy. It also lacks a local dimming feature to help control these problems.

TV shows – The TV shows performance is very decent. It isn’t bright enough to be used in a bright setting, and the screen finish’s handling of reflection isn’t great either.

Sports – Decent sports-watching TV. Since picture quality is maintained from the side higher than normal, it renders the UJ6300 very good for game watching parties with a number of visitors. There is also decently fine uniformity in grays and shades. Unfortunately, it doesn’t get really warm, which may be an issue in a sunny living room for afternoon sports.

Video Games – The UJ6300 delivers a satisfying video gaming experience. It has low motion blur, which renders rapid motion smooth and clear, and is one of the lowest possible input lags, and it looks quite responsive.

HDR Movies – Passable output on HDR. The visibility of the UJ6300 is a little higher in HDR than in SDR but it’s not perfect yet. The lack of local dimming and a wide variety of colors also restricts its capabilities.

HDR Gaming – Great performance in gaming on HDR. Although the HDR impact isn’t quite powerful, even in HDR the input lag and the overall gameplay performance remain good.

PC Monitor – Decent PC Monitor. The UJ6300 has really low input lag and motion blur, so it’s sensitive and not disruptive to use desktop. The viewing range is wide enough to be seen from close up. It can’t get very bright, however, so its RGBW pixel design will cause perfect on-screen objects to not look very clear.


The motion handling in this model is better, and also it has a very good fast response time.

The image appears on the screen doesn’t take time for loading because of faster response time.

Videos from a Blu-ray player and DVDs are clear without any effect on the clarity of the image, but when watching videos from an HTPC or cable a slight controlling should be done. This is not known by most people so it’s not a problem. The TV has a 60Hz screen which enables lower frame rate video to be interpolated.

Sound quality

Unfortunately, the LG UJ6300 doesn’t produce good sound. It is suggested to use a soundbar or any speakers to experience a better sound.
