TCL C755 and C855 are both great options on TCL's QD-Mini LED TV lineup, but the C755 is more of an entry-level model released in 2023, while the C855 is the upgraded and more premium model released in 2024. In this comparison, we'll take a closer look at what has been improved and what remains the same between the two models.
Key Takeaways
The TCL C855 outperforms the C755 with superior display technology, including higher peak brightness (3500 vs 1600 nits), HDR10+ Adaptive, and an advanced AiPQ Pro Processor. It also offers better audio with 2.2.2/2.1.2 channel speakers, while the C755 has basic 2.1 channel speakers.

Display
TCL C755
Both the TCL C755 and C855 use Quantum Dot technology with Mini LED backlighting, offering impressive color accuracy and brightness levels. However, as the newer model, the C855 has a slightly wider color gamut, higher local dimming zones, and superior brightness.
For example, the 98-inch C855 can reach up to 3500 nits of peak brightness, more than two times the C755 of the same size, which maxes out at 1600 nits. The smallest screen size of each model, 65-inch for the C855 and 50-inch for the C755, has brightness levels of 3300 nits and 1200 nits respectively, an even larger gap.
The C855 also features HDR10+ Adaptive, which can adapt HDR performance to ambient lighting conditions. It is a step up from the HDR10+ that the C755 offers.
On top of that, the processor on the C855 is superior. The AiPQ Pro Processor that powers the C855 is more advanced than the AiPQ Processor 3.0 used in the C755, providing better image optimization and overall picture processing capabilities.
Other display features like Dolby Vision IQ and IMAX Enhanced are equally present on both TVs.
Audio
TCL C855
TCL C755 and C855 have some similar audio features, including Dolby Atmos, DTS-HD, and DTS Virtual:X for immersive soundstage. However, with different speaker configurations, the C855 offers a more powerful and dynamic audio experience.
The 98-inch and 85-inch TCL C855 have 2.2.2 channel speakers, while the 75-inch and 65-inch sizes come with 2.1.2 channel speakers. Regardless of which size you choose, the TCL C855 will provide a more powerful and enveloping audio performance compared to the TCL C755, which uses just a 2.1-channel speaker for all its screen sizes.
