Our Verdict

LG C4 OLED

Samsung S90F OLED

The Samsung S90F OLED is a bit better than the LG C4 OLED. These two TVs have many of the same strengths: they both look amazing in a dark room, for example. The Samsung stands out better when watching HDR content, though, as colors are brighter and more vivid. The Samsung also looks better during the day thanks to its matte anti-glare coating.
