If you prioritize picture quality for movies and series and plan to watch in a dark room, the LG C3 OLED will offer superior performance with deeper blacks and better contrast. It's also slightly better for gaming due to a faster response time. However, this TV isn't as bright as its counterpart, so it might not perform as well in a very bright room. The Samsung QN90B LCD is brighter, making it a better fit for bright room viewing. It also has excellent color volume and a faster input lag, which can be beneficial for gaming. However, its contrast isn't as high as the LG C3 OLED, which means it won't deliver quite as deep blacks in a dark room. Both TVs are similarly priced and support Dolby Vision and other HDR formats, providing a versatile viewing experience. Consider your main usage scenarios and room conditions to make the best choice for your needs. Give Feedback

The LG C3 (OLED) is excellent for movies & TV, while the Samsung QN90B (LCD) is very good.
The LG C3 OLED excels in watching movies and cinematic TV due to its perfect black uniformity and infinite contrast ratio, which are byproducts of its OLED technology, ensuring deep blacks and excellent local dimming for a more immersive viewing experience. In contrast, while the Samsung QN90B LCD also performs very well with movies and cinematic content thanks to its high contrast and good local dimming, its blacks are not as deep, and the viewing angles are slightly more limited compared to the LG OLED, which can be important if multiple people watch from different angles.

The LG C3 (OLED) is very good for sports, while the Samsung QN90B (LCD) is good.
The LG C3 OLED is exceptional for sports because its perfect black levels and wide viewing angles enhance the contrast and consistency of images across the screen, essential for moving objects and side-viewing during games, with excellent handling of reflections and a best-in-class response time that keeps fast action clear. The Samsung QN90B LCD, while also good for sports, has slightly dimmer black levels and narrower viewing angles which may affect the image when watched from the side, but it also provides excellent reflection handling and a very good response time that ensures motion remains smooth.

The Samsung QN90B (LCD) is best in class for bright room, while the LG C3 (OLED) is very good.
The Samsung QN90B offers excellent brightness in both SDR and HDR, which contributes to its superior performance in bright rooms, alongside its excellent ability to handle reflections, avoiding glare from ambient light. Conversely, the LG C3, although very good with reflections, has slightly lower SDR and HDR brightness, which might make it less optimal for brightly lit environments compared to the Samsung model.

"The QN90B delivers one of the brightest pictures we’ve ever seen, showcasing HDR content better than just about every LCD/LED TV on the market. If all you’re planning on doing is watching cable TV, broadcast channels, and a fair share of streaming shows or movies, the QN90B is sure to impress. All four of the QN90B’s HDMI 2.1 ports support 4K gaming at 120fps a centerpiece feature of the Xbox Series X and PlayStation 5."
