The Sony X850E offers great value for size with decent picture quality. At 65", it's the largest 4K TV in this price bracket that doesn't compromise on picture quality.
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 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 has 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 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 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 doesn't like it, but the X850E can do this really well for those who enjoy it.
