Pro Good for dynamic content
This TV is a great option for fast-paced content such as sports and video games due to the quick response time. This makes sure the content doesn't appear blurred out due to fast movement on-screen. A full pixel color transition on the TV's panel takes 15 milliseconds.
Pro Strong smart TV platform
The UK6300 runs on LG’s WebOS. The interface is functional and easy to navigate.
LG Content Store has a wide range of apps, including popular media streaming services such as YouTube, Amazon, Netflix, etc., and many other third-party apps, which are all kept up-to-date.
Pro Good viewing angle
The UK6300 is a good TV for rooms with wide seating because it offers a better viewing angle than other TVs at this price-point. The blacks are consistent at any viewpoint, and the color and brightness shifts aren’t too bad – they become noticeable at moderate angles. Colors shift at 22 degrees, whereas brightness shifts at 27 degrees.
Pro Fair motion handling
The motion on this TV looks smooth and clear thanks to the TV's pixels that can change their colors very fast as well as the optional black frame insertion feature that works at a high frequency.
The TV's full pixel response time measures at only 12.1 ms - fast enough to eliminate long traces of the artificial motion blur.
Additionally, the motion looks clear, and the details look sharper thanks to the TV's black frame insertion feature. This feature allows the TV to insert black frames in between of the actual content frames. This makes the details appear definite.
Pro Good for gaming
The VIZIO D-Series offers decent gaming experience thanks to its high overall responsiveness and excellent motion handling. The gaming feels lag-free because of the TV's low input lag that measures at only around 22.2 milliseconds.
The VIZIO D-series runs SmartCast which is free of ads.
Con Lower color resolution
The picture is less detailed and lower in quality due to the RGBW pixel structure, which means that only 75% of the total panel's pixels can produce colors.
Con Struggles with darkness
The UK6300 can’t reproduce deep blacks and dark room viewing is not too great. This is due to the mediocre contrast ratio, no black uniformity and the lack of local dimming.
The blacks tend to look grey due to the brightness difference between white and black - the native contrast ratio is only 1096:1. Compared to other TVs this is a very low value.
Moreover, the TV has less than ideal black uniformity and no local dimming. The standard deviation for black uniformity is approximately 3%, which, when compared to the much lower percentages of competing TVs, is very disappointing.
Con Bad for group watching
The VIZIO D-Series isn't the best TV to watch with a crowd because those who sit at an angle to the TV will experience degraded image because of the TV's lousy viewing angles. As soon as the angle between the viewer and a TV gets more significant than 13 degrees, the black levels start to degrade. This is a common problem for the VA TVs.
Con Can't fight glare
The VIZIO D-Series is a poor choice for bright rooms because the TV's peak brightness is not high enough to fight glare emitted by other sources of light.
