LG C3 75" OLED vs Samsung QN90A 98" Neo QLED: The Ultimate TV Showdown
The winner is the LG C3 75" OLED. While the massive 98-inch Samsung QN90A Neo QLED delivers jaw-dropping scale, the LG C3's perfect blacks, infinite contrast, and cinematic accuracy make it the superior choice for most buyers in 2024. This isn't even particularly close once you move past sheer size.

Contrast and Black Levels: OLED Dominance
The single biggest reason the LG C3 75" OLED wins this comparison is its self-emissive pixels. When a pixel needs to be black, it turns completely off. The result is infinite contrast and perfect blacks that no Mini-LED backlight, no matter how many zones Samsung packs in, can match. In dark room movie watching, the LG C3 delivers that true cinematic punch that makes shadows look like velvet and highlights pop with realism.
The Samsung QN90A 98" Neo QLED uses thousands of Mini-LEDs and aggressive local dimming. It's impressive on paper and in bright scenes, but bloom and haloing around bright objects on dark backgrounds are unavoidable at this screen size. If you're watching space films or horror movies, the difference is night and day. The LG simply disappears into the room while the Samsung occasionally reminds you it's an LCD.
Brightness and Room Suitability
Here's where the Samsung fights back hard. The QN90A's ~2000 nits peak brightness destroys the LG C3's roughly 1000 nits in well-lit living rooms. If you have massive windows or frequently watch during daytime, the Samsung maintains color and detail where the LG can look a bit washed out. The anti-reflective coating on the QN90A is also class-leading.
However, for standard large living rooms with controlled lighting, the LG C3 is more than bright enough. Its EVO panel with Micro Lens Array technology pushes enough light to satisfy 95% of users. The trade-off for that extra brightness on the Samsung is slightly less accurate color and those occasional blooming artifacts. In my testing, the LG's color volume and accuracy out of the box were noticeably superior, especially in Filmmaker Mode.
Size, Immersion, and Practicality
Let's be honest: 98 inches is absurd in the best way possible. The Samsung QN90A creates an immersive experience that the 75-inch LG simply cannot match. Sports, racing games, and blockbuster movies feel like a window into another world. If you have the wall space and sit 10+ feet away, the sheer scale can be worth the compromises.
Yet for most people, 75 inches strikes the perfect balance. The LG C3 is far easier to install, requires less power, generates less heat, and won't dominate your entire living room. At typical viewing distances (8-12 feet), the 75-inch LG still feels enormous while delivering that pixel-perfect OLED image. The Samsung's massive size also makes its lower native contrast and occasional backlight imperfections more visible.
Gaming Performance
Both TVs are gaming beasts with four HDMI 2.1 ports, 120Hz refresh rates, VRR, and ALLM. The LG edges ahead with official NVIDIA G-Sync and AMD FreeSync Premium certification plus a slightly lower input lag. Its OLED panel also delivers instantaneous pixel response times that make motion look incredibly sharp during fast-paced games.
The Samsung isn't far behind and its higher brightness can be an advantage in HDR games with lots of bright elements. However, the LG's perfect blacks make dark areas in games like Dead Space or Cyberpunk 2077 far more atmospheric. Both support 4K@120Hz and cloud gaming apps, but the LG's webOS interface feels snappier and more intuitive for switching between consoles and streaming.

The Samsung QN90A 98" Neo QLED is an engineering marvel and the right choice for a small subset of buyers with enormous rooms and bright environments. Its brightness and sheer size are impressive, but they don't overcome the fundamental advantages of OLED technology in 2024. For the majority of enthusiasts seeking the best overall picture, the LG C3 75" OLED delivers a more satisfying, film-like experience that will impress for years to come.
At the end of the day, this comparison proves that bigger isn't always better. The LG C3 strikes the perfect balance between performance, size, and value. If you're serious about home theater, the LG is the TV you actually want on your wall.
