When comparing LG UK6300 55" (55UK6300PUE) vs Sony X850E 75" (XBR75X850E), the Slant community recommends Sony X850E 75" (XBR75X850E) for most people. In the question“What are the best TVs?” Sony X850E 75" (XBR75X850E) is ranked 172nd while LG UK6300 55" (55UK6300PUE) is ranked 206th. The most important reason people chose Sony X850E 75" (XBR75X850E) is:
The X850E has a wide color gamut that allows it to reproduce the colors necessary for true HDR, and it has an average peak brightness level of ~400 nits that allows it to light up these colors properly. Thanks to that, HDR pictures look decent and highlights will look fairly good. However, the HDR performance can’t get better than that, due to the average peak brightness of ~400 nits which isn’t really enough for details to truly stand out, and it lacks local dimming.
Ranked in these QuestionsQuestion Ranking
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 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 Decent for HDR content
The X850E has a wide color gamut that allows it to reproduce the colors necessary for true HDR, and it has an average peak brightness level of ~400 nits that allows it to light up these colors properly. Thanks to that, HDR pictures look decent and highlights will look fairly good.
However, the HDR performance can’t get better than that, due to the average peak brightness of ~400 nits which isn’t really enough for details to truly stand out, and it lacks local dimming.
Pro Good for sports
The X850E looks fluid thanks to its excellent color uniformity and decent handling of motion.
It can display large, same-color objects like football fields really well - they will look natural and uniform.
Fast-moving objects, like football, will also look smooth. The panel only requires ~14ms to fully change the pixels color, resulting in fast-moving objects not leaving any trails on the screen, eliminating virtually all motion blur.
Pro Great ecosystem of third-party apps
The X850E runs on Android TV that has access to the Google Play Store. The Play Store has a nice selection of apps, but normal Android apps won't work unless they support Android TV.
Pro Decent picture quality
The X850E looks really good in dark scenes, thanks to its decent contrast ratio of 4500:1 and excellent black uniformity.
It can produce blacks that are 4500 times darker than the brightest white, and the black uniformity is especially good - there’s barely visible flashlighting, where edges of the screen have a light on them when displaying a black image, and the screen is evenly bright. This makes it perform really well in dark scenes.
Colors look vibrant because of the panel’s high peak brightness levels of ~350 nits for SDR & ~400 nits for HDR. With these brightness levels, it can get bright enough to fight glare. Along with its great handling of reflections, pictures will still look good in decently-lit environments without dull colors.
Pro Interface is ads-free
There are no ads on the X850E’s interface.
Pro Excellent motion interpolation capabilities
The X850E can increase the framerate of content to either 60Hz or 120Hz.
It guesses which frames are missing based on the previous and next frame, and inserts the missing frame in between them. This produces a really strong soap opera effect, where images look really smooth.
This might look weird to some people that don't like it, but the X850E can do this really well for those who enjoy it.
Pro Suitable for gaming
The X850 has a relatively low input lag of ~35ms that makes it a decent pick for gaming. Most players will feel in sync, however, it might be a little unresponsive for competitive or demanding gamers.
It’s also acceptable for HDR gaming because the input lag does not increase in HDR mode.
Pro Excellent for 24p content
The X850E is an excellent option for those who watch content from an antenna/satellite box, DVD/Blu-ray player or Apple TV. It can detect eliminate jerky playback that is common in content from these sources.
Pro Offers best value for screen size in this price bracket
The X850E has the largest screen size at 65” for the cheapest when compared to its direct competitors. Similarly-sized models from its direct competitors cost much more.
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 Not suitable for group watching
The X850E has a narrow viewing angle that makes it unsuitable for watching with groups.
Its picture quality starts to deteriorate significantly when viewing from just ≥20° away from the screen's center. The colors will start degrading really quickly.
Con Might require color calibration
Some viewers might find the X850E’s white balance to be slightly off out of the box, so a brief calibration might be required if you notice it. Fortunately, all the optimal color settings are available on the internet and isn’t hard to find.
