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 Ideal for group watching
This TV is an ideal choice for those who like to enjoy an occasional sports game or a movie with a bunch of friends or family because it's picture quality remains solid even while viewed from a distance thanks to its IPS panel structure.
Pro Can make low frame-rate content appear smooth
This TV is an excellent option for those who like to re-watch their collection of Blu ray DVDs occasionally because it can increase the smoothness of such content by using its interpolation features. Interpolation allows the TV to boost up the framerate of content making it appear more fluid and less stuttery.
Pro Fair picture quality
The Sony X850F offers the picture quality that is on par with what the other TVs in its price range offer. It is capable of reproducing decent bright scenes as well as some reasonably good-looking dark scenes.
This TV offers relatively good looking, vivid color because of its bright IPS panel. Its brightness peaks at around 460 nits, which is perfectly enough for those interested in SDR content. As it runs an IPS panel, its colors look a lot crisper than what the VA competitors offer.
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 Can't play HDR well
Because of its low peak brightness, the X850F cannot produce vivid highlights while dealing with the HDR content. It's HDR peak brightness reaches only 460 nits, which is not as high as what the competitors in its price bracket offer.
