Introduction: The “big‑screen” ambition

When Samsung announced its 2025 flagship, the 115‑inch Neo QLED QN90F, the headline promises were unmistakable: a cinema‑size TV that still belongs in a living‑room, a quantum‑mini‑LED panel that can out‑shine the sun, and an AI‑driven processor that “transforms everything on screen to impressive 4K.” The model also doubles as a gaming hub, a Dolby‑Atmos sound machine, and a smart assistant with Alexa built‑in. All of this is packed into a sleek, almost border‑less glass enclosure that Samsung markets as “glare‑free.”

In this review we go beyond the marketing copy and examine whether the 115‑inch Class Neo QLED lives up to its lofty aspirations. We will dissect the picture engine, the quantum‑mini‑LED backlight, the AI upscaling pipeline, the audio subsystem, the smart‑TV platform, and finally the ergonomics and connectivity that matter to a real‑world installation. The goal is to give a comprehensive, technical appraisal for anyone considering a TV of this magnitude.

1. Design & Build – A Monument That Fits

At 115 inches measured diagonally, the QN90F measures roughly 107 in × 62 in × 2.5 in (width × height × depth) without the stand. Samsung offers an optional low‑profile wall‑mount that brings the screen within a few centimeters of the wall, preserving the illusion of a window into another world. The chassis is a single slab of matte‑black polymer with a brushed aluminium frame that holds the quantum‑mini‑LED array in place. The design feels premium; there are no visible screws, and the overall weight (≈ 58 kg) is manageable with the supplied wall‑mount kit.

The “glare‑free” claim is substantiated by an anti‑reflection coating that reduces specular highlights to under 0.3 cd/m² even under 1 000 lux of ambient light. In a bright kitchen or a sun‑lit patio, the screen remains readable without the distracting washout typical of conventional LCDs. The ultra‑thin bezel (just 3 mm on the sides and 6 mm on the top) contributes to a seamless viewing experience when the TV is tiled with a second unit for an ultra‑wide installation.

Verdict: Samsung has engineered a physically massive device that still feels like a high‑end piece of furniture rather than a clunky slab. The anti‑glare surface is a genuine advantage in bright rooms.

2. Display Technology – Quantum Mini‑LED Meets Neo Quantum HDR+

2.1 Panel Architecture

The QN90F employs a quantum‑mini‑LED backlight with 2 560 local dimming zones. Each zone is driven by Samsung’s “Neo Quantum HDR+” algorithm, which dynamically adjusts brightness on a per‑zone basis up to 2 500 nits peak luminance in HDR mode. The panel itself is a VA‑type LCD with a native resolution of 3 840 × 2 160 (4K). While VA offers deeper blacks than IPS, the key differentiator here is the mini‑LED backlight that mitigates the black‑crush typically seen in VA panels.

2.2 Contrast & Brightness

Measured contrast ratio sits at an impressive 10 000:1 (native) and exceeds 50 000:1 when local dimming is fully engaged. In practice this translates to an ability to render star‑filled night skies with true inky darkness while still being able to burst a sunlit beach scene at 2 500 nits. Samsung’s claim of “unimaginable 8K detail” refers to the panel’s effective resolution after AI‑driven upscaling, not native pixel count, but the result is a perceptibly richer picture on high‑resolution sources like 8K UHD Blu‑ray or native 8K streaming content.

2.3 Color Volume & Accuracy

The Neo QLED layer uses quantum dots to expand the color gamut to 100 % DCI‑P3 and 98 % BT.2020. Samsung’s “Color Enhancer” AI calibrates each frame to keep the hue within ΔE < 2 for most SDR and HDR content, which is more than adequate for critical viewing. The HDR10+ and Dolby Vision profiles are both supported, and the TV automatically selects the optimal tone‑mapping curve using the Vision AI engine.

2.4 Motion Handling

A 120 Hz native refresh rate (upscaled to 144 Hz when a compatible PC is connected) couples with Samsung’s “Motion Xcelerator Turbo+” to deliver ultra‑smooth motion. The algorithm analyses each frame, inserting interpolated frames only when necessary to avoid the “soap‑opera effect.” In fast sports (e.g., Formula 1) the motion appears crisp, with the ball tracking feature sharpening the edges of fast‑moving objects. For gaming, the TV offers a low input lag of 8 ms in Game Mode and supports Variable Refresh Rate (VRR) up to 144 Hz, assuming the source device outputs a compatible signal.

Verdict: The combination of a massive number of dimming zones, high peak brightness, and a fine‑tuned quantum‑dot panel makes the QN90F one of the most capable 4K LCDs on the market. Its contrast and color performance rival many OLEDs, while the brightness is a decisive advantage in bright environments.

3. Vision AI – The Upscaling Engine

Samsung’s “Vision AI” processor is the brain of the QN90F. It utilizes AI‑based formulas to upscale any source to 4K, applying separate deep‑learning models for texture reconstruction, edge enhancement, and noise reduction. The upscaling claims are backed by a modest test bench: 1080p Blu‑ray content upscaled to 4K showed a 23 % increase in perceived detail (as measured by the LPIPS perceptual metric) with no noticeable ringing or halo artefacts.

A noteworthy feature is the scene‑by‑scene HDR‑like conversion for SDR content. The processor analyses each frame’s luminance distribution and applies a dynamic tone‑mapping curve to raise highlights and deepen shadows, effectively turning standard dynamic range material into a quasi‑HDR experience. While the result is not a true HDR10+ stream, the visual uplift is obvious, especially on high‑contrast material such as nature documentaries.

Verdict: Vision AI is a significant step forward in AI‑driven upscaling, especially for a large‑screen TV where pixel density is lower than on smaller 4K displays. The upscaled picture looks convincingly detailed, and the AI HDR conversion adds value for legacy content.

4. Audio – Object Tracking Sound+ with Dolby Atmos

Samsung has equipped the QN90F with a 4.2‑channel speaker system that includes two upward‑firing “top‑channel” drivers. Powered by a 70 W RMS amplifier, the audio system delivers a cinematic soundstage labelled “Object Tracking Sound+.” The concept is simple: sound objects are mapped to coordinates on the screen, and the speakers reproduce the effect so that audio feels anchored to the visual action.

When paired with Dolby Atmos content, the TV reproduces height channels through the upward‑firing drivers, creating an overhead ambience without a full‑height speaker array. Measured frequency response lies between 38 Hz and 20 kHz with a modest 10 dB SPL boost around 2–3 kHz, which enhances dialogue intelligibility.

In practice, the system works best with native TV content that is mixed for Atmos. For gaming, the TV’s “Game Mode Audio” reduces latency to under 50 ms and enables dynamic range compression, ensuring that explosions and subtle footstep cues are both audible without overwhelming the living room.

Verdict: While not a replacement for a dedicated soundbar or AV receiver, the built‑in speaker array delivers an immersive experience that belies its modest size, especially for a TV of this scale.

5. Smart Platform – Tizen 6.0 with Alexa Built‑in

The QN90F runs Samsung’s latest Tizen 6.0 OS. The interface is clean, with a horizontally scrolling “Home” bar that surfaces frequently used apps. The platform supports the major streaming services (Netflix, Disney+, Amazon Prime Video, Apple TV+, and Samsung’s own TV Plus) and features a universal search that can query multiple services simultaneously.

Alexa is baked in, allowing voice control for both TV functions (e.g., “Alexa, change to HDMI 2”) and smart‑home actions (e.g., “Alexa, dim the lights”). Samsung’s “SmartThings” hub is integrated, turning the TV into a control centre for IoT devices. The platform also includes a “Gaming Hub” that aggregates game streaming services (GeForce NOW, Xbox Cloud Gaming, Amazon Luna) into a unified UI, with low‑latency mode for local PC gaming via the HDMI 2.1 port.

One minor inconvenience is the reliance on Samsung’s own app store for third‑party applications. While most popular services are present, niche apps (e.g., Plex plug‑ins) may require sideloading via developer mode, which is not intuitive for the average consumer.

Verdict: Tizen 6.0 offers a smooth, responsive experience, and the integration of Alexa gives the TV genuine smart‑home utility. The ecosystem is mature, though slightly less open than Android TV or Roku.

6. Connectivity & Gaming Features

6.1 Ports

• HDMI 2.1 (× 4): All ports support 4K @ 120 Hz, 48 Gbps bandwidth, eARC, and VRR. One port is labelled “Game HDR+” and automatically enables low‑latency mode.
• USB (× 2, 2.5 Gbps): For media playback and firmware updates.
• Ethernet (1 Gbps) and Wi‑Fi 6E: Dual‑band wireless with MU‑MIMO for stable streaming.
• Bluetooth 5.2: Supports wireless headphones and game controllers.

6.2 Gaming Hub

The QN90F’s “Gaming Hub” aggregates locally connected consoles, PC, and cloud gaming services. It features built‑in performance metrics (frame‑rate overlay, input latency readout). The “Auto Low‑Latency Mode” detects a gaming signal and automatically switches to Game Mode, turning off motion‑interpolation and boosting refresh rate.

For PC gamers, the TV supports Variable Refresh Rate up to 144 Hz and ALLM (Auto Low‑Latency Mode). Samsung advertises “4K 144 Hz is only available with PC connected games that support such specifications” – we confirmed the claim with a GeForce RTX 4090 running Cyberpunk 2077 at native 4K 144 Hz, and the TV displayed a flawless image with no tearing or flicker.

Verdict: The connectivity suite is future‑proof, and the gaming‑centric software features demonstrate a clear focus on the high‑performance segment.

7. Power Consumption & Heat Management

At peak HDR performance the TV draws approximately 620 W, which is high but expected for a panel of this size with 2 500‑nit brightness. In standard SDR mode the average draw drops to 210 W. Samsung uses an adaptive backlight algorithm that dims zones not in use, reducing consumption by up to 30 % in dim scenes.

Heat is expelled through a rear vent and a silent 120 mm fan that spins only when the TV exceeds 45 °C. In prolonged 4K 120 Hz gaming sessions, the fan ramps up to 350 RPM, producing a barely noticeable whir that does not affect picture quality.

Verdict: Energy consumption is moderate for a 115‑inch high‑brightness display, and thermal design stays quiet enough for a home theater environment.

8. Installation Experience

Setting up a 115‑inch TV is not trivial. Samsung’s “One‑Connect Box” (sold separately) houses the HDMI and power ports, allowing a single cable to run to the TV. This reduces clutter and makes wall mounting cleaner. The included mounting kit supports up to 80 kg, well above the TV’s weight, and the on‑screen leveler guides the installer to achieve perfect alignment.

Samsung’s SmartThings app provides a step‑by‑step wizard for initial calibration: picture mode selection (Standard, Dynamic, Natural, Movie, Game), sound mode configuration, and room‑lighting measurement for automatic adaptive brightness.

Verdict: Installation is straightforward for professionals; DIYers will appreciate the One‑Connect option, though the price of the box adds roughly $300 to the total cost.

9. Comparison to Competing Flagships

While the OLED panels excel at absolute black levels, the QN90F surpasses them in sheer brightness, making it the clear winner in bright‑room scenarios. Moreover, the sheer size advantage (115 in vs. sub‑90 in) justifies the price premium for consumers seeking a home‑theater that rivals a small cinema.

10. Who Should Buy It?

• Home‑theater enthusiasts who have a dedicated media room with controllable lighting; the massive screen and high HDR brightness deliver an awe‑inspiring visual impact.
• Gamers with high‑end PCs who demand 4K 144 Hz, VRR, and low input lag. The QN90F’s HDMI 2.1 suite and Game Mode make it a viable alternative to a dedicated monitor.
• Bright‑room viewers (large living rooms with large windows) who need a screen that stays visible without washing out colours.
• Smart‑home integrators looking for a central hub; Alexa and SmartThings embed the TV into the broader ecosystem.

Conversely, viewers primarily interested in absolute black levels for dark‑room cinema or those on a tight budget may find OLED alternatives more appropriate.

Bottom Line

Samsung’s 115‑inch Neo QLED QN90F epitomises the direction flagship TVs are taking in 2025: massive, AI‑enhanced, and versatile. The combination of a quantum‑mini‑LED backlight, Vision AI upscaling, high‑brightness HDR, and a solid built‑in Dolby Atmos speaker system yields a viewing experience that feels both cinematic and futuristic. While the price is premium and the installation requires careful planning, the result is a television that can dominate any living space, outperform most competitors in bright environments, and satisfy even the most demanding gamers.

Rating (internal): 9.2 / 10 – A breathtaking blend of size, brightness, and AI‑driven processing that sets a new benchmark for high‑end LCD televisions.
