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 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.
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 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.
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 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.
