When comparing LG UK6300 55" (55UK6300PUE) vs Sony X900E 49" (XBR49X900E), the Slant community recommends Sony X900E 49" (XBR49X900E) for most people. In the question“What are the best TVs?” Sony X900E 49" (XBR49X900E) is ranked 6th while LG UK6300 55" (55UK6300PUE) is ranked 56th. The most important reason people chose Sony X900E 49" (XBR49X900E) is:
The X900E looks true-to-life with really deep blacks, clear details, and captivating colors. Pictures look realistic with lots of details. There’s great depth to them and you’ll be able to see everything in the picture stand out. Dark scenes are excellent with nice shadow details that are not overly dark to the point where some details get drowned out. This is thanks to really deep black levels, enabled by the panel’s contrast ratio of about 5500:1 which means it can produce blacks that are 5500 times darker than the brightest white. This can be pushed even further to over 6500 with local dimming. The colors are lifelike and accurate even without any calibration by the user. They will look really vibrant even in bright scenes because of the panel’s high peak brightness levels of ~500 nits for SDR & ~550 nits for HDR. Even in a decently lit environment, the X900E’s picture quality can still hold up as the panel is great at handling reflections and it can get bright enough to fight off glare.

Pro Great versatility
Apart from being an excellent TV for movies, the X900E is a decent choice for gaming and sports thanks to its decent input lag, low motion blur, great screen uniformity, and a 120 Hz native refresh rate that makes images look smoother.
The input lag of ~35ms is sufficient for most gamers, apart from competitive ones, to stay in sync with what's on the screen. The low motion blur of ~11ms and a refresh rate of 120 Hz ensures that everything will look smooth - fast-moving objects won't leave any trails on the screen.
It’s also viable for watching sports because the panel also has no issues with displaying large, same-color objects on screen, like football fields.
Pro Great at handling glare
Even in a decently lit room, the X900E's picture quality will remain more or less the same as in a dark room.
The colors will still look vibrant because the panel is bright enough to fight off glare. It has peak brightness levels of ~500 nits for SDR & ~550 nits for HDR, and reflections are also significantly reduced by the panel's semi-gloss finish.
Pro Excellent for HDR content
On top of the excellent picture quality, the X900E has everything essential to an immersive HDR experience: decent local dimming, great coverage of HDR colors, and high HDR peak brightness level.
Its excellent black levels are further improved with local dimming, which can make parts of the screen darker when the image calls for it. This results in an increase in overall picture quality with black levels becoming much deeper, so highlights will stand out further.
The panel can reproduce the wide range of colors required for true HDR playback because of its wide color gamut, which covers ~65% of the standard colors required for HDR according to the Rec. 2020 color space. This is considered great for reproducing HDR details, and it can display these colors accurately at different brightness levels.
Along with the the high peak brightness level of ~550 nits, HDR scenes will look stunning and you'll be able to see HDR details really pop.
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 Bad sound quality
The sound quality of X900E's built-in speakers is bad. It can't produce much bass and sounds rather flat. There is also noticeable distortion at high volumes.
Con Lacks support for Dolby Vision
The X900E currently only supports the HDR10 format for HDR content.
Con Not suitable for group watching
The X900E has a narrow viewing angle that makes it unsuitable for group watching.
Its picture quality gets worse when viewed from off-center angles. At ≥20° away from the center, the blacks start degrading into greys and colors will start looking dull. Brightness levels start decreasing at ≥50° away from the center.
