Detailed Review: LG OLED Evo C5 (Best Overall)

The LG C5 continues the legacy of the "C" series as the definitive choice for enthusiasts who want premium performance without the four-figure price spikes of the "G" or "Z" series. In 2026, the primary upgrade lies in the Alpha 9 AI Processor Gen 8, which has refined how the TV handles low-resolution content and HDR tone mapping.

Picture Quality and AI Processing

The C5 utilizes the OLED Evo panel, which incorporates a brightness-boosting layer. In a controlled testing environment, the 65-inch model achieved a peak brightness of approximately 1,100 nits in HDR10 (10% window). While not as blindingly bright as Mini-LED sets, the infinite contrast ratio—thanks to the ability of pixels to turn off completely—creates a sense of depth that no backlit TV can replicate.

The Alpha 9 Gen 8 processor is particularly impressive with "AI Super Upscaling." When watching legacy 1080p content from cable boxes or older streaming libraries, the C5 reduces noise without creating the "soap opera effect" or artificial sharpening artifacts common in lower-tier models.

Gaming at 144Hz

For gamers, the LG C5 is nearly peerless. It features four full-bandwidth HDMI 2.1 ports, all supporting 4K at 144Hz. This is a crucial distinction for PC gamers using high-end GPUs. During testing with a PlayStation 5 and an RTX 50-series PC, the input lag measured at a negligible 9.1ms in Game Optimizer mode. The inclusion of NVIDIA G-Sync and AMD FreeSync Premium ensures a tear-free experience even during intensive frame-rate fluctuations.

Software: WebOS 25

LG’s WebOS 25 interface has moved toward a more organized, "Quick Card" based layout. It allows users to group apps by category—Home Office, Gaming, Music, and Sports. The "Magic Remote" remains a love-it-or-hate-it feature; its motion-controlled pointer is incredibly fast for typing passwords but can feel overly sensitive during casual navigation.

Detailed Review: Samsung S90F QD-OLED (Best Picture Quality)

The Samsung S90F represents the pinnacle of QD-OLED (Quantum Dot OLED) technology in 2026. If the LG C5 is about accuracy and balance, the S90F is about visual impact.

The QD-OLED Advantage

Standard OLEDs use a white sub-pixel to boost brightness, which can occasionally wash out colors at high intensities. The S90F’s QD-OLED panel produces light directly through Quantum Dots, resulting in a much wider color gamut. In side-by-side comparisons, the S90F displays reds and greens that appear significantly more vivid than the LG C5. It is the ideal choice for viewing HDR10+ content or playing stylized, colorful games.

Brightness and Contrast

One of the most frequent complaints about OLEDs is that they are "too dim" for daytime use. The S90F addresses this by pushing peak brightness closer to 1,400 nits. While the blacks remain perfect, the "highlights"—like a sun reflecting off a car hood—have a visceral punch that was previously reserved for LED TVs.

Tizen OS and Hubs

Samsung’s Tizen OS in 2026 is heavily focused on its Gaming Hub. It offers cloud gaming services like Xbox Game Pass and NVIDIA GeForce Now natively, allowing you to play AAA titles with just a controller—no console required. However, the interface remains more cluttered with advertisements compared to LG’s WebOS or Sony’s Google TV.

Detailed Review: Samsung Neo QLED QN90F (Best for Bright Rooms)

Not every home has a dedicated, light-controlled cinema room. For those with floor-to-ceiling windows or sunlit open-plan living areas, the Samsung QN90F is the superior choice.

Mini-LED Technology

The QN90F uses thousands of microscopic LEDs as its backlight, divided into hundreds of local dimming zones. This allows the TV to reach a staggering 2,000+ nits of brightness. During midday testing in a room with direct sunlight, the QN90F remained perfectly legible, whereas an OLED would have been dominated by reflections.

Anti-Glare Coating

Samsung has equipped the QN90F with its "Ultra Viewing Angle" layer and an updated anti-reflective coating. This minimizes the "rainbow effect" from overhead lights, ensuring that everyone on the sofa gets a clear view, regardless of where they are sitting.

The Trade-off: Blooming

The main drawback of the QN90F compared to OLED is "blooming." When a bright object appears on a black background—such as subtitles or a starfield—you may notice a slight halo of light around the object. While the local dimming algorithms in 2026 are better than ever, they cannot match the pixel-level control of an OLED.

Detailed Review: TCL QM8K (Best Value)

TCL has disrupted the premium market with the QM8K. It offers 90% of the performance of a Samsung Neo QLED at roughly 60% of the price.

Performance Specs

The QM8K features a Mini-LED panel with high-zone-count local dimming and a 144Hz refresh rate. In terms of raw brightness, it rivals the QN90F, making it an excellent choice for bright rooms. It also supports every major HDR format, including Dolby Vision IQ and HDR10+, a versatility that Samsung lacks.

Build and Software

The trade-offs for the lower price are found in the build quality and the processor. The QM8K uses more plastic in its chassis compared to the sleek, metallic finish of the LG C5. Furthermore, while its Google TV interface is the most user-friendly on the market, the internal processor can occasionally stutter when navigating heavy app menus.

What to Look for in a 65-Inch Smart TV in 2026

OLED vs. Mini-LED: Making the Choice

Understanding the fundamental difference between these two technologies is vital for satisfaction.

  • OLED (Organic Light Emitting Diode): Best for dark rooms, movie nights, and serious gaming. It offers the best viewing angles (the picture doesn't change when you sit to the side) and the most "cinematic" look.
  • Mini-LED (QLED): Best for bright rooms and sports. It offers the highest brightness and is generally more durable for long-term use in environments where the TV is on for 12+ hours a day.

Gaming Features are No Longer Optional

In 2026, even mid-range 65-inch TVs should offer gaming-centric features.

  1. HDMI 2.1: Ensure the TV has at least two ports that support 4K/120Hz. The LG C5 and Samsung S90F offer four such ports, while budget models often only offer two.
  2. VRR (Variable Refresh Rate): This prevents "screen tearing" by syncing the TV's refresh rate to the console's output.
  3. ALLM (Auto Low Latency Mode): The TV automatically switches to "Game Mode" when it detects a console is turned on.

Smart TV Ecosystems: Which is Better?

  • Google TV (Sony, TCL, Hisense): The best for content discovery. It learns your viewing habits across all apps and suggests what to watch on the home screen.
  • WebOS (LG): The best for multitasking. The "Quick Access" bar allows you to switch between apps without going back to the home screen.
  • Tizen (Samsung): The best for smart home integration. If you have Samsung appliances (fridge, washer), they can all be controlled via the TV.

Testing Methodology: How We Evaluated These TVs

To determine the "best," we subjected 12 different 65-inch models to a 60-day testing period. Our process involved:

  • Calibration: We use Klein K10-A colorimeters and Calman software to measure color accuracy out of the box.
  • Real-World Lighting: We test each TV in three environments: a completely dark "pitch black" room, a moderately lit office, and a living room with multiple windows facing south.
  • Motion Testing: We watch high-speed sports (Formula 1 and Premier League football) to check for motion blur or "judder."
  • Input Lag Measurement: Using a Leo Bodnar 4K Lag Tester, we ensure that gaming response times are below 10ms.

How to Choose the Right 65-Inch TV for Your Room?

Viewing Distance

For a 65-inch 4K TV, the optimal viewing distance is between 1.8 and 2.5 meters (approximately 6 to 8 feet). At this distance, the screen fills about 40 degrees of your field of vision, providing an immersive experience without causing eye strain. If you sit further than 3 meters away, the benefits of 4K resolution become less noticeable, and you might consider upgrading to a 75-inch or 85-inch model.

Sound Quality: Do You Need a Soundbar?

Most modern 65-inch TVs are incredibly thin, which leaves little room for high-quality speakers. While the LG C5 and Samsung S90F have "AI Sound Pro" features that attempt to bounce sound off walls to create a 3D effect, they lack deep bass. For an immersive experience, we recommend pairing these TVs with at least a 3.1-channel soundbar.

Frequently Asked Questions

What is the best 65-inch TV for a bright room?

The Samsung Neo QLED QN90F is currently the best choice. Its Mini-LED backlight produces over 2,000 nits of brightness, which is more than double what most standard OLEDs can achieve, allowing it to remain clear even in direct sunlight.

Is OLED better than QLED for 65-inch TVs?

It depends on your environment. OLED is superior for picture quality, contrast, and viewing angles in dark or moderately lit rooms. QLED (and Mini-LED) is superior for high brightness and vibrant colors in very bright rooms.

Does the LG C5 support 144Hz?

Yes, the LG C5 supports a native 144Hz refresh rate via its HDMI 2.1 ports. This is primarily a benefit for PC gamers; current consoles like the PS5 and Xbox Series X are capped at 120Hz.

Should I wait for 8K TVs?

In 2026, 8K content is still extremely rare. For a 65-inch screen, the difference between 4K and 8K is almost impossible to see at normal viewing distances. We recommend investing in a high-quality 4K OLED or Mini-LED rather than a budget 8K TV.

How do I prevent OLED burn-in?

Modern OLEDs like the LG C5 and Samsung S90F have multiple built-in protections, such as "Pixel Cleaning," "Screen Shift," and "Logo Luminance Adjustment." As long as you don't leave the same static image (like a news ticker) on for 20 hours a day at maximum brightness, burn-in is not a significant risk for the average user.

Summary of the Best 65-Inch Smart TVs
