The winner of this head-to-head is clear from the start: the LG OLED C2 delivers a superior overall experience with perfect blacks, infinite contrast, and confirmed 83-inch availability that the Samsung QN90A simply cannot match. While Samsung's Neo QLED offers impressive brightness, the LG OLED C2's self-emissive pixels and modern gaming features make it the better choice for most buyers in 2022 and beyond.

Picture Quality: The OLED Advantage Shines Through

Let's cut straight to the chase: the LG OLED C2 destroys the Samsung QN90A when it comes to pure picture quality in a dark room. With its self-emissive pixels that can turn completely off, the C2 delivers perfect blacks and infinite contrast ratios that no Mini-LED backlight system can replicate. The QN90A's local dimming zones, while impressive for a 2022 LCD, still show some blooming and haloing around bright objects on dark backgrounds. This is especially noticeable during movies like "The Batman" or "Dune" where stars in space or city lights create distracting glow.

In well-lit rooms, the Samsung QN90A fights back with significantly higher peak brightness. Its Mini-LED array can push close to 2000 nits, making HDR content pop with dazzling highlights that the LG OLED C2's roughly 1000-nit capability can't quite match. However, the C2's superior color volume and more accurate factory calibration make its HDR performance feel more natural and cinematic. The LG's EVO panel technology also improves brightness over previous generations, closing the gap more than many expect.

Gaming Performance: Both Strong, But LG Has the Edge

Gamers will be happy with either TV, but the LG OLED C2 pulls ahead with its confirmed feature set and lower input lag. Both support 4K at 120Hz, Variable Refresh Rate (VRR), and Auto Low Latency Mode (ALLM) across their four HDMI 2.1 ports. The C2 additionally supports Dolby Vision Gaming at 120Hz, giving Xbox Series X and PS5 owners access to the best HDR implementation currently available in gaming.

The Samsung QN90A's Game Bar is excellent and slightly more customizable than LG's, allowing quick tweaks to picture settings without pausing the action. However, early reports suggest the QN90A suffers from occasional VRR flicker that the C2 has largely eliminated through its updated Alpha 9 Gen 5 processor. For serious gamers who value responsiveness and the deepest blacks during dark scenes in games like "Dead Space" or "Cyberpunk 2077," the LG OLED C2 is the undisputed champion.

Smart Features and Usability: webOS vs Tizen

LG's webOS 22 platform on the C2 feels more polished and intuitive than Samsung's Tizen interface in 2022. The C2 offers faster navigation, better app organization, and the excellent Magic Remote with its pointer functionality that makes typing and menu navigation a breeze. Both platforms support major streaming services, but LG's ThinQ integration gives it a slight edge for smart home users.

Voice control is strong on both, with Bixby on Samsung and the more natural ThinQ AI on LG. The C2 also includes built-in support for Apple AirPlay 2 and HomeKit, making it more friendly for mixed-device households. Samsung counters with its excellent Multi View feature that splits the screen more effectively than LG's version. Still, the overall user experience favors the LG OLED C2 for its speed and refinement.

Design and Build Quality

The LG OLED C2 features an incredibly thin panel with the distinctive Gallery Design that allows it to sit nearly flush against the wall when using the optional wall mount. Its stand is minimalist and sturdy. The Samsung QN90A has a more traditional but attractive design with slim bezels and a central stand that works well for soundbars. Both TVs feel premium, but the C2's 83-inch option gives it a clear advantage for those wanting a massive screen without the depth of traditional LCD backlights.

Final Verdict

The LG OLED C2 is the clear winner in this comparison with a score of 7.5/10 against the Samsung QN90A's 5/10. Here's why:

While the Samsung QN90A excels in extremely bright rooms and offers competitive performance, the LG OLED C2's fundamental advantages in picture quality make it the TV most enthusiasts should buy. If you're still waiting for final specs on the QN90A before deciding, that's understandable, but the C2 has already proven itself as the superior choice for 2022 premium TV buyers. Don't settle for good enough when perfect contrast is available at similar prices.
