TCL, Samsung or LG? Compare display technology, gaming features, smart OS and audio before buying
Compare six premium 4K smart TVs from TCL, Samsung and LG, covering QLED, OLED, QNED and LED panels, refresh rates, gaming features, sound and smart platforms.
A premium 65-inch TV is no longer simply about getting a bigger screen. At this size, the panel technology, contrast performance, refresh rate, HDR support and smart platform can have a pretty big impact on what you see and how you use your TV. OLED, QLED and Mini LED-based QNED models also approach picture quality differently. Here in this comparison, we'll bring together six Amazon listings from TCL, Samsung and LG. The selection ranges from TCL's QLED T6C and T8D to Samsung's QLED QEF1 and OLED S85H, along with LG's QNED82 and NANO NU87. Amazon customer feedback is also considered separately for each model.
Our Picks
Research-Backed Choices
Every product we recommend is chosen through a combination of Primary Research and Secondary Research.
The TCL T8D sits towards the performance-focused end of TCL's QLED range, combining QD-Mini LED technology with local dimming and a 144Hz native refresh rate. TCL also lists an ONKYO 2.1 Hi-Fi audio system for the T8D range. Dolby Vision and Dolby Atmos support make it relevant for movie watching, while the high refresh rate gives it an obvious gaming angle.
What are buyers saying on Amazon?
Customers praise the T8D's picture and sound, particularly its punchy colours and deep blacks, and several consider it worth the price. Feedback on display reliability is mixed, with one buyer reporting pixelated artefacts. Performance is generally smooth, although some mention noticeable screen latency.
Why should you choose this product?
The T8D is particularly relevant for buyers who want a high-refresh premium QLED rather than OLED. Its QD-Mini LED approach, 144Hz native refresh rate and ONKYO audio make it a versatile option for movies, sports and gaming.

The TCL T6C takes a simpler route than the T8D, using a QLED panel, AiPQ processing and an HVA panel. TCL's official material also lists Dolby Vision and Dolby Atmos for the T6C range. The combination targets buyers who want quantum-dot colour and modern smart-TV features without moving to TCL's more elaborate Mini LED tiers.
What are buyers saying on Amazon?
Customers generally like the picture quality, with sharp 4K clarity and vibrant QLED colours receiving positive feedback. Installation is also praised for being quick and convenient. However, reliability feedback is mixed, with some buyers reporting blank screens or TVs that did not work out of the box. Sound opinions are divided.
Why should you choose this product?
The T6C is aimed at buyers who want the core QLED experience without stepping up to TCL's more advanced T8D hardware. Its appeal is the combination of QLED, AiPQ processing, Dolby Vision and Google TV.
Samsung's S85H changes the panel technology completely, using OLED pixels that illuminate individually. The 65-inch model has a 4K resolution and 120Hz refresh rate with VRR support. It also includes HDR10+, Dolby Atmos, Tizen and gaming features such as G-SYNC and FreeSync Premium. For gamers, 4K 120Hz support is available through the TV's motion and gaming features.
What are buyers saying on Amazon?
Customers are highly impressed with the S85H's picture quality, particularly its deep blacks, vivid colours and contrast. The UI and gaming performance also receive positive mentions, including 120Hz, G-SYNC and FreeSync features. Some buyers, however, feel the built-in speakers lack loudness and detail, while others find the price high.
Why should you choose this product?
The S85H is primarily for viewers who care about OLED contrast and gaming responsiveness. Its 120Hz VRR support, self-emissive panel and Samsung gaming features make it particularly relevant for console and PC gamers who also watch movies.
The Samsung QEF1 is the conventional QLED option in Samsung's lineup here. It uses a 4K QLED panel with the Q4 AI Processor, Quantum HDR, HDR10+ support and 4K upscaling. Samsung also includes OTS Lite, Q-Symphony and a 20W two-channel speaker system. Tizen powers the smart experience.
What are buyers saying on Amazon?
Customers praise the picture quality and several say it compares favourably with OLED TVs, while performance is also viewed positively. Sound feedback is mixed, with some finding it good and others too quiet. Buyers also criticise the remote. Screen reliability is a concern in some reviews, including reports of failures within four months.
Why should you choose this product?
The QEF1 is suited to buyers who want Samsung's QLED colour, upscaling and Tizen ecosystem without moving to an OLED television. It is a straightforward choice for mixed TV, streaming and everyday entertainment.
LG's QNED82BLA combines a 4K QNED Mini LED display with the Alpha 8 AI Processor 4K Gen3. Its 120Hz native refresh rate can reach VRR at 144Hz, while Dolby Vision, HDR10 and HLG cover major HDR formats. LG also includes Dolby Atmos, webOS 26, three HDMI inputs and eARC.
What are buyers saying on Amazon?
Customers praise the QNED82's picture quality, including its ability to make standard 1080p content look close to 4K. Sound and value receive mixed reactions. The remote gets negative feedback, while brightness and reliability also divide buyers, with some reporting concerns about the screen.
Why should you choose this product?
The QNED82 is aimed at buyers who want LG's webOS experience alongside Mini LED picture technology and high-refresh gaming support. Its 120Hz native panel, VRR 144Hz capability and Dolby Vision support give it a broad use case.
The LG 65NU870BPLA is a 65-inch 4K UHD TV from LG's 2026 lineup, powered by the α7 Processor Gen9. It uses LG's Nano Detail Enhancer for picture processing, supports HDR10 and HLG, and runs webOS 26. Gaming features include ALLM, HGiG, Game Optimiser, and VRR up to 60Hz.
What are buyers saying on Amazon?
Customers praise the TV's 4K resolution and picture quality, while feedback on performance is mixed. Some buyers find it responsive, whereas others report a sluggish webOS experience. Sound, colours, installation, remote control and connectivity also receive mixed reactions, with value for money divided among buyers.
Why should you choose this product?
The 65NU870BPLA makes sense for buyers who want LG's latest webOS experience and α7 processing without moving to a QNED or OLED model. Its 65-inch 4K panel and gaming features make it a straightforward everyday entertainment option.

Factors to consider when buying a premium 4K smart TV
- Panel technology: OLED, QLED and Mini LED-based QNED displays work differently. OLED uses self-illuminating pixels, while QLED and Mini LED TVs rely on backlighting. Think about contrast, brightness and the type of content you watch most.
- Refresh rate and gaming: If you have a PS5, Xbox Series X or gaming PC, check the native refresh rate, VRR and HDMI capabilities rather than relying on a generic "gaming mode" label.
- HDR formats: Dolby Vision, HDR10+ and standard HDR support can affect how compatible movies and shows look. Check which formats your preferred streaming services and devices use.
- Room size and viewing distance: A 65-inch screen already needs a reasonable viewing distance, while the supplied LG NU87 is 75 inches. Measure the wall or TV unit before choosing the larger option.

FAQs
Is OLED better than QLED for a 65-inch TV?
They use different display technologies. OLED can produce very deep blacks because each pixel is self-illuminating, while QLED TVs use quantum-dot technology with a backlight and can offer a different brightness and colour approach.
Is 120Hz important on a 65-inch TV?
It can be useful for sports and gaming because a higher refresh rate can provide smoother motion. It matters most when the source device and content can take advantage of the higher refresh rate.
What is Mini LED on a TV?
Mini LED uses a large number of smaller LEDs for backlighting and can provide more precise control of brightness and contrast than conventional backlighting. It is still different from an OLED panel.
Should I buy a 65-inch or 75-inch TV?
Consider your room size, viewing distance and available wall or furniture space. A 75-inch TV provides a substantially larger viewing area but needs more physical space.
Is Dolby Vision important on a 4K TV?
Dolby Vision can improve HDR presentation when the TV and source content support it. It is worth checking the HDR formats supported by your streaming services and external devices.
