Our Verdict
Samsung QN90C/QN90CD QLED
LG C4 OLED
The LG C4 OLED is better than the Samsung QN90C/QN90CD QLED, 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.
