LG B4 OLED 55 vs Samsung 65" QN90C Neo QLED TV

The clear winner is the LG B4 OLED 55. With superior contrast, perfect blacks, full VRR and ALLM support, and a dramatically lower price tag, the LG delivers a more cinematic and responsive experience for the majority of buyers. The Samsung QN90C is no slouch with its bright panel and larger screen, but it simply cannot match the depth and accuracy of the OLED in most real-world scenarios.

Picture Quality: Blacks, Contrast and Color Accuracy

The LG B4 OLED dominates this category with self-emissive pixels that turn completely off for true black levels. This creates infinite contrast ratios that make every scene feel three-dimensional. Dark movie scenes in titles like "The Batman" or "Dune" reveal shadow detail that the Samsung simply cannot match without crushing blacks or introducing haloing around bright objects.

The Samsung QN90C uses a Mini-LED backlight with hundreds of dimming zones. While impressive on paper, it still suffers from blooming and clouding in high-contrast content. In very bright rooms the extra nits help the Samsung fight ambient light, but in any controlled lighting environment the LG's perfect blacks deliver a far more premium, reference-level image. Color accuracy is also superior out of the box on the LG after a quick calibration; Samsung's Quantum Dot layer produces vibrant colors but they often look oversaturated compared to the LG's more natural tone mapping.

Gaming Performance and Features

Gamers should run to the LG B4 without hesitation. Both TVs support 120Hz, VRR, and ALLM, but the LG implements them more comprehensively across its four HDMI 2.1 ports. Input lag on the LG measures an incredible sub-10ms in Game Optimizer mode. The inclusion of Dolby Vision Gaming further sweetens the deal for console owners using PS5 or Xbox Series X.

The Samsung is no stranger to gaming with its excellent Game Bar and low latency, but the lack of Dolby Vision support is a noticeable omission in 2023. Additionally, the LG's OLED panel has virtually no motion blur thanks to near-instantaneous pixel response times. Fast-paced titles like "Call of Duty" or racing games look noticeably sharper on the LG. The only advantage the Samsung holds is its larger 65-inch canvas, which some PC gamers may prefer for immersive gameplay.

Brightness, HDR Performance and Room Suitability

Neither manufacturer has published final peak brightness figures yet, but real-world testing shows the Samsung Neo QLED reaching significantly higher sustained brightness levels, especially in full-screen HDR content. This makes the QN90C the better choice for very bright living rooms with large windows. The LG still delivers excellent HDR with its ~1000 nit peaks on small highlights, but it cannot compete with the Samsung when the sun is blasting through the blinds.

For dedicated home theater rooms or evening viewing, however, the LG's superior contrast and lack of blooming make HDR content pop in a way the Samsung cannot replicate. The LG also handles wide viewing angles far better; the picture remains consistent even when watching from the side of the room, whereas the Samsung's VA panel loses contrast and color off-angle.

Smart Features, Sound and Build Quality

Both platforms are excellent in 2023. LG's webOS 24 is lightning fast with an intuitive remote that doubles as a pointer and voice controller. Samsung's Tizen is equally responsive and offers strong smart home integration. The LG edges out a win here thanks to broader streaming app support and the inclusion of Dolby Vision for services like Netflix and Disney+.

Built-in audio is serviceable on both but neither replaces a soundbar. The LG's OLED panel allows for slightly better bass response due to its thinner chassis design. Build quality feels premium on both, though the LG's ultra-thin panel gives it a more modern, gallery-like appearance when wall mounted.
