Comparison Description

When comparing the TCL C755 vs C855 [tcl c755 vs c855 Which Best], the technological advancement between these two models becomes immediately clear. The C855 is TCL’s next-generation take on Mini LED technology, with dramatic improvements in a number of key areas.

Visual Performance

The most significant distinction lies in visual performance. Although the C755 provides a staggering 1600 nits of peak brightness and up to 1344 zones of local dimming, the C855 takes this to a whole new level by elevating the specifications to 3500 nits and up to 2304 zones respectively. This translates to over double the peak brightness and much greater control of backlighting, allowing for richer blacks and more accurate highlights in HDR content.

New Technologies

The C855 also features new technologies not found on the C755, such as the six-crystal light-emitting chip for brighter lights and the wide-angle even-light lens for wider backlight uniformity. All these create the C855’s better contrast ratio of up to 35,000,000:1 from the C755’s 16,000,000:1.

Audio Performance

Audio performance is significantly improved in the C855 from a 2.1 channel 50W ONKYO setup to a more advanced 2.2.2 channel setup with as much as 120W of power and up-firing speakers specifically for Dolby Atmos content. This produces a more immersive audio experience without the use of external speakers.

Design and Features

In terms of design, the C855 offers an ultra-slim profile with a new magnetic mounting system and enhanced cable management, presenting it with a sleeker, more premium design than the already slim C755.

Both TVs have much in common, such as a 144Hz refresh rate with AMD FreeSync Premium Pro for gaming, Google TV as the operating system, and compatibility with all HDR formats. The C855, however, does include HDR10+ Adaptive (which adapts to room lighting conditions) and a more advanced AiPQ PRO processor with extra AI-assisted picture modes.

Size and Value Proposition

The C755 continues its size range superiority (providing 50″ and 55″ versions not found on the C855) and in value proposition, generally costing between 15-25% less than the equivalent C855 model. The C755 strikes most consumers as having the right performance and price mix, whereas the C855 is for those looking for the absolute best visuals and audio regardless of expense.

Final Verdict

Having carefully scrutinized both TCL models [tcl c755 vs c855 Which Best], our verdict is that they both are outstanding options within their respective budget ranges.

The TCL C755 is the better value for a high-end viewing experience. With its peak brightness of 1600 nits, up to 1344 local dimming zones, and full HDR support, it provides a picture quality that is on par with far pricier units from other manufacturers. Its 144Hz refresh rate and gaming features make it ideal for next-gen console gamers, while the ONKYO 2.1 channel audio delivers adequate sound for most living rooms. For the average consumer, the C755 is the best balance of price and performance.

The TCL C855, although quite expensive, is worth the premium with truly significant upgrades. The incredible 3500 nits peak brightness and as many as 2304 local dimming zones make HDR performance out of the question for most TVs available. The advanced QLED PRO technology with 97% DCI-P3 coverage produces outstanding color accuracy, and the advanced 2.2.2 channel audio system produces a sound experience all too rarely achieved by integrated TV speakers. For film buffs, serious gamers, or those who want the very best visual performance, the C855 is worth the cost.

Recommendation

Our recommendation [tcl c755 vs c855 Which Best] would be:

Select the TCL C755 if you desire great performance at a lower price point, require a 50″ or 55″ size option, or if you already have (or will buy) a separate sound system.
Choose the TCL C855 if you require the very best image quality with full HDR effect, prefer superior in-built audio quality, value the ultra-thin look with magnetic base, and are prepared to pay for these high-end features.

Both models demonstrate TCL‘s remarkable advancements in QD-Mini LED technology [tcl c755 vs c855 Which Best], with the decision between them coming down to your spending budget, room size, and how much of a priority those added performance boosts are to your gaming and viewing experience.

For the average consumer looking for the optimal mix of performance and value, the C755 will be the prudent option. For those who seek the very finest picture quality at any cost, the C855 provides an absolute visual treat worth its premium pricing.

Comparison FAQs :

Is the TCL C855 worth the additional expense over the C755?

Whether or not the TCL C855 is worth its additional expense is a matter of your viewing habits and budget. The C855 has major upgrades in the form of 3500 nits peak brightness (compared to 1600 nits), increased local dimming zones (2304 vs 1344), and better audio (2.2.2 channel vs 2.1). For film buffs and those who value high-end image quality, particularly for HDR content, the C855’s enhancements are significant and apparent. Nevertheless, for daily use and general viewing, the C755 provides outstanding performance at a lower price point.

Which one performs better for gaming: C755 or C855?

Both versions provide outstanding gaming features such as 144Hz Variable Refresh Rate (VRR) and AMD FreeSync Premium Pro certification. The fundamental gaming performance is similar across both TVs, with the same input lag quality. The C855 can offer a small advantage with its greater peak brightness for HDR titles and better contrast, but serious gamers will be content with either model. If gaming is the top priority, the C755 is the better value, but the C855 provides a more upscale gaming experience with slightly superior visual quality.

Do I need a soundbar with these TVs?

The difference in sound quality between these sets is noticeable. The C755 has a 2.1 channel 50W ONKYO audio system that provides good sound for casual viewing, but could use a soundbar to enhance the experience of watching movies. The C855 features a more advanced 2.2.2 channel sound system (up to 120W) with dedicated up-firing speakers to take advantage of Dolby Atmos, offering considerably better integrated audio many find reduces the necessity for external speakers. If sound quality is a priority and you’d like to forgo the extra cost of a soundbar, the C855’s better sound system might be worth its extra price.

What are the available sizes for each model?

The TCL C755 provides greater size options with sizes ranging from 50″ to 98″ (precisely: 50″, 55″, 65″, 75″, 85″, and 98″). The C855 is a premium model and only comes in larger sizes: 65″, 75″, 85″, and 98″. If you require a TV for a smaller room or are on a budget, the smaller size options of the C755 might be the deciding factor in your purchase.

How do the Mini LED backlighting systems differ?

Both models employ QD-Mini LED technology, but the C855 is a major leap forward. The C855 has up to 2304 local dimming zones (compared to 1344 in the C755) and adds the six-crystal light-emitting chip and wide-angle even-light lens technologies. These advancements provide more accurate backlight control, darker blacks, improved blooming control, and enhanced brightness uniformity. For critical consumers who observe backlight problems or view material in black rooms, the C855’s better Mini LED implementation will be a demonstrably better viewing experience.

Are these TVs suitable for bright room viewing?

Both sets are good in bright rooms, but there is a big difference. The C755 achieves 1600 nits maximum brightness which is more than adequate for most brightly lit rooms. But the C855’s outstanding 3500 nits peak brightness offers much greater visibility in extremely bright rooms and enables HDR highlights to cut through even with ambient light. The C855 also has a better anti-reflection coating that works more effectively to eliminate glare. For spaces with big windows or high ambient light, the C855 has a distinct advantage.

What are the key differences in smart features between the models?

The fundamental smart platform experience is virtually the same on both models, with both using Google TV with hands-free voice control and Google Assistant integrated. Both have video calling (with supported camera), Multi-View capability, and AirPlay 2. The C855 has a marginally more responsive interface thanks to its new processor. But for the average viewer, the smart TV experience will be very much the same, and smart features shouldn’t be the main consideration between these two models.

How do these TVs perform for movie viewing?

Both TVs are great for movie lovers with great features such as Dolby Vision IQ, HDR10+, and IMAX Enhanced certification. The C855 offers a more upscale cinematic experience with its significantly higher peak brightness, more local dimming zones for improved contrast, and better audio system with up-firing speakers. These enhancements are especially apparent with 4K HDR movies. The C755 still provides outstanding movie performance superior to most of its competition at its price point, but film buffs seeking the very best experience will enjoy the C855 improvements.

Which TV offers more accurate colors?

Both TVs provide outstanding color performance with Quantum Dot. The C755 ranges 96% in the DCI-P3 color space, and the C855’s QLED PRO technology extends it slightly to 97% with a Delta E measure less than 0.99. For the average viewer, this distinction will not be apparent in day-to-day content. Professional content producers and those requiring perfect color accuracy may find the C855’s slight edge useful. Both TVs offer rich, accurate colors beyond what is standard on LED/LCD displays.

How long will these TVs stay up to date with technology trends?

Both sets are well-stocked for future-proofing with HDMI 2.1 inputs, 4K@144Hz support, VRR, ALLM, and all major HDR formats. The C855, a year newer (2024 vs 2023 for the C755), makes use of more advanced developments in Mini LED technology and processing. The C855’s much greater brightness and contrast potential could allow it to stay competitive longer as HDR material continues to challenge brightness limits. Still, each should stay technologically current for a few years of typical usage.
