Pro Good for gaming
The UJ6300 is a decent choice for gaming thanks to its extremely low input lag, excellent response time, and full 4K 60 FPS support.
In terms of input lag, this TV outperforms almost every currently available high-end TV. The low input lag makes the TV great for fast games. The motion blur is really low at ~17ms, so fast-moving objects won't leave any trails at all.
It’s also compatible with 60 Hz 4K input which makes it suitable for high-end console gaming.
Pro Has an excellent smart TV platform
The UJ6300 runs on the webOS smart platform. It has a great ecosystem of apps, ranging from media streaming services (Netflix, Amazon, YouTube, etc.) to third-party apps. Support for these apps are also first-class with up-to-date features and good performance; for instance, the YouTube app supports 360-degree video playback.
Pro Handles reflections well
The UJ6300 does a decent job at lowering the intensity of glare. Reflections are kept to a minimum thanks to the panel's semi-gloss finish. In fact, only around 1.9% of total light is reflected - a feat surpassed only by a handful of higher-end TVs.
Pro Fairly good upscaling capabilities
The UJ6300 can upscale 480p, 720p, and 1080p content quite well. The majority of details will be preserved, although there might be some artifacts on the sides of an image.
Pro Good at handling dynamic content
The UJ6300 is great at handling motion, making it a good choice for displaying fast and dynamic content. Fast-moving objects don't leave any discernible trails behind them, thanks to its low motion blur of only ~17ms.
Pro Compatible with current-gen consoles
The UJ6300 will run content from the PS4 Pro and Xbox One X smoothly, and its input lag stays low at ~13ms even with HDR-enhanced 4K content. You will not notice any increased delay when switching from SDR gaming mode to HDR.
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 Dark scenes look bad
The UJ6300 fails to reproduce deep and uniform blacks. Its dark images look smoky and grey-ish, which makes many dark scenes look awful. Furthermore, the panel’s low contrast ratio of only 1314:1 makes the blacks look distorted and flat.
Con Some artifacts might occur
Because of the TV’s specific RGBW pixel structure, some unwanted artifacts might occur while the TV is displaying 4K content. The problem with the RGBW pixel structure is that only 75% of the total panel's pixels can produce colors, which results in lower quality and less detailed picture.
Con The remote looks outdated
Apart from some tiny details, it seems like LG adapted their old remote from 2016 to the UJ6300. The remote is as basic as it can get. It does not have any smart functions that can be found on higher-tier LG TVs. In fact, it is very disappointing that this TV does not have LG’s new Magic Remote.
Con Can't handle intense glare
The UJ6300 can’t fight glare well in really bright environments because of the panel’s low peak brightness level. The brightness peaks at only ~170 nits for SDR, which is really low. Even cheaper and lower-tier TVs are usually brighter.
Con Suffers from minor image retention
The UJ6300 suffers from minor image retention issues. If a static image is on the screen for more than 10 minutes, it gets burned in and you'll be able to see it retained on the screen faintly, which is really unpleasant. Fortunately, this does not cause permanent pixel damage and disappears in around 5 minutes.
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.
