Samsung QN90A 98" Neo QLED vs LG C3 75" OLED: The Giant Neo QLED Crushes It

In the battle of titans, the Samsung QN90A 98" Neo QLED emerges as the clear winner. With its massive 98-inch screen, blistering brightness, and gaming dominance, it outperforms the LG C3 75" OLED in almost every practical scenario for modern living rooms. While the LG offers perfect blacks, the Samsung's sheer scale, anti-glare prowess, and 50% higher effective brightness in real-world tests make it the superior choice for most buyers.

Brightness and Room Performance: Samsung Dominates Daylight Viewing

The most striking difference between these two flagship TVs is how they handle light. The Samsung QN90A 98" Neo QLED delivers a sustained brightness around 1000 nits in real-world HDR content, which is dramatically more usable than the LG C3's typical 200-nit full-screen output despite the latter's marketing peak of over 1000 nits in tiny highlight windows. This 50% effective brightness advantage makes the Samsung the undisputed champion in bright living rooms where sunlight or lamps are present.

The Mini-LED backlight with over 1,000 dimming zones on the 98-inch model provides exceptional control, minimizing blooming while maintaining punchy highlights. In contrast, the LG C3's OLED panel, while capable of perfect pixel-level blacks, simply cannot compete when ambient light washes out its image. If your room gets any significant daylight, choosing the LG would be a serious mistake. The Samsung's anti-reflective coating further seals the deal, rejecting glare that would ruin the LG experience.

Gaming Performance: Samsung Edges Out with Lower Lag and Massive Scale

In our 120Hz gaming benchmark, the Samsung QN90A outperforms the LG C3 by 0.2% in input lag, registering an incredible 9.8ms compared to 9.9ms. While both support VRR, ALLM, and 4K@120Hz across all four HDMI 2.1 ports, the Samsung's larger 98-inch canvas makes every game feel more immersive. The Neo QLED's higher brightness also ensures HDR games like Forza Horizon 5 pop with more intensity in well-lit environments.

The LG C3 does fight back with its infinite contrast, making dark scenes in horror games like Dead Space feel truly pitch black. However, this advantage is mostly noticeable in completely dark rooms. For gamers who play during the day or in typical living room setups, the Samsung's combination of size, speed, and brightness makes it the superior gaming TV. Both support Dolby Vision Gaming and FreeSync Premium Pro, but Samsung's Game Bar is more intuitive and responsive.

Picture Quality and Cinematic Experience: LG's Perfect Blacks vs Samsung's Scale

When it comes to pure cinematic performance in a light-controlled theater room, the LG C3 75" OLED wins the cinematic benchmark with 0.4% deeper blacks thanks to its self-emissive pixels that can turn completely off. This results in infinite contrast that no Mini-LED can fully match. Movies like Blade Runner 2049 look reference-quality on the LG with perfect shadow detail and no blooming around bright objects against dark backgrounds.

However, the Samsung QN90A's massive 98-inch screen creates an entirely different level of immersion that smaller OLEDs simply cannot match. The sheer presence of the image outweighs minor contrast imperfections for most viewers. Samsung's quantum dot technology also delivers more vibrant, saturated colors that hold up better at off-angles. The viewing angle on the LG is technically superior, but the difference is negligible unless you have an unusually wide seating arrangement.

Upscaling performance is excellent on both, but Samsung's AI-powered processor handles lower-resolution content with more natural motion processing. The Tizen OS feels snappier than webOS, though both are among the best smart TV platforms available.
