Our Verdict
Sony X90L/X90CL
LG B4 OLED
The LG B4 OLED is better than the Sony X90L/X90CL. The Sony's contrast is excellent, but the LG's OLED panel gives it perfect blacks, easily giving it the edge over the Sony. When it comes to brightness, the Sony is the slightly brighter product of the two, especially in SDR, giving it the edge in brighter rooms even though the LG has better reflection handling. If you like to host large viewing parties, it's hard to beat an OLED like the LG B4, as its viewing angle is vastly wider than the Sony's; the image stays mostly uniform even when watched from extreme angles. The LG is also the better choice if you're a gamer due to its nearly instantaneous response time and lower input lag than the Sony. The Sony does have better image processing overall, but it doesn't offset the LG's image quality advantage.
