Product Specifications & Ratings¶

Overall Rating: ⭐⭐⭐⭐½ (4.7/5.0)

Product Overview¶

In 2025, two flagship technologies dominate the K HDR television market: LG’s OLED and Samsung’s QLED, specifically exemplified by LG’s B5 OLED and Samsung’s S90D OLED along with the Neo QLED QN85D Mini-LED series. Each approach embodies different engineering philosophies aimed at optimizing picture quality, smart features, and user experience for varied consumer needs.

LG’s OLED line continues to leverage self-emissive WOLED technology, where individual pixels generate their own light, enabling perfect black levels through pixel-level dimming. This yields unmatched contrast ratios and cinematic image fidelity favored by movie enthusiasts and professionals alike. The LG B5 OLED model features a 65-inch 4K panel integrated with the stable and responsive webOS smart platform, supporting Dolby Vision HDR for rich dynamic range and color nuances. Its extremely low input lag of approximately 0.1 milliseconds makes it attractive for competitive gaming as well.

Samsung’s QLED models, represented by their 65-inch S90D OLED and the Neo QLED QN85D, employ advanced quantum dot technology to enhance color precision and brightness. The QD-OLED variant in the S90D uses quantum dots to produce broader, more vivid color gamuts, achieving about 125% coverage of the DCI-P3 color space. Meanwhile, Neo QLED with Mini-LED backlighting features thousands of tiny LEDs for precise local dimming zones, dramatically boosting peak brightness above 2,000 nits and preserving sharp contrast in bright viewing conditions. Both Samsung options run the Tizen OS platform, offering frequent updates and a rich content ecosystem tailored for varied entertainment needs.

This review dives deep into the specifications, performance tests, real-world usage impressions, and pros and cons of these prominent models. It culminates in nuanced purchase guidance to aid consumers in selecting the optimal HDR TV in alignment with their preferences, environments, and budgets.

In-Depth Review¶

Panel Technology & Display Characteristics¶

LG B5 OLED 65″: Employing WOLED technology, LG’s approach generates white light via OLED pixels filtered through color filters, producing natural, film-like colors with exceptional black levels and infinite contrast ratios. Peak brightness is approximately 1,600 nits, supporting Dolby Vision as well as HDR10 and HDR10+. The 120Hz native refresh rate combined with ultra-low input lag (0.1ms) supports smooth motion clarity and highly responsive gaming.

Samsung 65″ OLED S90D: Samsung’s QD-OLED panel diverges by using quantum dots that emit pure, vibrant colors without needing filtering. This technology results in a broader color gamut (~125% DCI-P3) and eye-catching saturation, especially beneficial for bright and colorful content like animation. Peak brightness around 1,240 nits is slightly lower than LG’s but compensated by more intense color saturation. It supports HDR10 and HDR10+ but lacks Dolby Vision. Tizen OS powers its smart features with optimized gaming and multimedia modes.

Samsung Neo QLED QN85D 55″: The Neo QLED combines quantum dots with Mini-LED backlighting, providing over 2,000 nits peak brightness and highly precise local dimming. This allows excellent visibility and contrast in well-lit rooms, tackling a historic OLED weakness. It supports HDR10+ and HLG for broadcast standards and delivers low input lag with an enhanced game mode. The panel structure trades some black-level purity for brightness and impact in dynamic scenes such as sports and action movies.

Detailed Specifications Overview¶

Performance Testing¶

Independent professional tests confirm LG’s OLED superiority in black-level accuracy and contrast, with near-perfect pure blacks and color accuracy at 95% DCI-P3. Its Dolby Vision support significantly enhances HDR video fidelity. The 120Hz refresh rate is smooth and reliable, ideal for 4K HDR movie playback and console gaming.

Samsung OLED’s strength lies in its wider color gamut generating more vivid images, although its pure black level is marginally less perfect due to panel architecture. Samsung’s Neo QLED demonstrates remarkable peak brightness (>2000 nits) suitable for high ambient light environments, with local dimming greatly improving dynamic range. It excels in sports and fast-action content but cannot match OLED’s pixel-level black performance.

Real-World Experience¶

Viewing movies on the LG B5 OLED is an immersive experience, with extraordinary black depths and shadow detail revealing subtle cinematic nuances. The self-emissive technology eliminates any halo or light bleed, lending authentic picture realism that professional videographers trust. Its support for Dolby Vision HDR vividly brings out highlights and color gradations in HDR streaming content. The smooth 120Hz panel with 0.1ms latency suits gamers playing competitive titles requiring instantaneous reaction, while webOS ensures intuitive navigation and app variety.

Samsung’s 65″ OLED S90D impresses with vibrant, punchy colors that make bright scenes — such as animations or vividly colored content — visually striking. Though blacks are slightly less deep than LG’s WOLED, the enhanced color volume feels more dynamic. Samsung’s Tizen platform is robust and rich in apps, with regular updates and useful smart features enhancing the overall experience.

Samsung Neo QLED stands out in well-lit living rooms with floor-to-ceiling windows or bright daylight. Its high peak brightness ensures clear visibility despite intense ambient light, while precise local dimming maintains image contrast without significant blooming. Its fast response and low input lag enhance live sports viewing and gaming experiences, though less true black fidelity occasionally results in minor light haloing around bright objects.
