In the question“What are the best TVs?” Sony X850E 75" (XBR75X850E) is ranked 48th while LG C8PUA OLED 77" (OLED77C8PUA) is ranked 120th. 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 Ideal for gaming
The LG C8 is an excellent option for gamers out there thanks to the TV's exceptional motion handling capabilities and high responsiveness.
While gaming on this TV you'll see no traces of motion blur thanks to the TV's superb motion handling capabilities. Every pixel of the LG C8 needs only 1.7 milliseconds to change its color fully, leaving no room for motion blur.
The LG C8 offers lag-free gaming experience because of its low input lag that measures at around 21 milliseconds. Only a few TVs in this class can offer matching performance.
Pro Exceptional overall picture quality
Regarding its overall picture quality, there are only a few high-end TVs that can compete with the LG C8. The VV performs extremely well in both bright and dark environments thanks to its infinite contrast ratio, high peak brightness, exceptional overall uniformity, and wide color gamut.
The LG C8 can reproduce astonishingly crisp and vivid colors of very high uniformity thanks to the TV's high peak brightness, massive color gamut, and high overall uniformity. Offering the peak brightness of almost 700 nits, the LG C8 is one of the brightest OLED TVs available on the market. Additionally, the TV covers 98% of the DCI-P3 color gamut - only a handful of high-end TVs are that color-rich. The colors don't look washed-out thanks to the TVs high overall uniformity.
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 Risk of burn-ins
Just like virtually every 2018's OLED TV, the LG C8 can suffer from image retention and permanent burn-ins if a user leaves static content for an extended period of time.
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.
