Our Verdict

Samsung QN90C/QN90CD QLED

LG C4 OLED

The LG C4 OLED is better than the Samsung QN90C, but they excel in different contexts. The LG has better contrast and image processing, so it's the better choice if you like to watch movies in a dark room. It's also the better gaming TV due to its near-instantaneous response time and 4k @ 144Hz capabilities on all four HDMI 2.1 ports; the QN90C is limited to 4k @ 120Hz on all of its ports, although the smaller 43 and 50-inch models do have 4k @ 144Hz. The Samsung is the better option for bright rooms; however, it gets brighter in HDR and SDR, and its reflection handling is just as fantastic as that of the LG, so the Samsung stays bright and vibrant even under heavy glare.
