Pros
Pro Good for gaming
The UK6300 offers a responsive and lag-free gaming experience. It has low input lag and a good refresh rate.
The TV has one of the lowest input lags in the market – approximately 11.5 ms. The “Game” and “_PC_” picture modes help achieve this. Moreover, the latency increase while gaming in 4K or HDR is extremely tiny and doesn't go past 1 ms.
The TV is great for high-end console gaming. It has a 60Hz native refresh rate and you can game in 4k60Hz if you enable the “HDMI Ultra HD Deep Color” setting.
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 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 Exceptional reflection handling
The high-quality glossy screen finish allows this TV to absorb 98.6% of the incoming light, which is a remarkable result. Only a couple of high-end TVs can match that result.
Pro Stunning picture quality
The Sony A8F is an exceptional home-theater option because it offers exceptional picture quality that only a couple TVs on the market can match. The TV performs remarkably in both dark and bright environments.
Cons
Con Advertisements
The interface features advertisements and suggested content and there is no way to remove them or opt out.
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 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 Risk of burn-ins
Just like every other OLED TV present on the market, the F8A can suffer from severe, permanent burn-ins if a static image is left on the screen for an extended period.
