Vidda C3 Ultra vs. C2 Ultra: A Generational Evolution in Three-Colour Laser Projection

In the high-end home projection market, Vidda's C series has always been the benchmark for three-colour laser technology. The C2 Ultra, launched in 2024, impressed the market with its ‘super optical zoom’ and ‘zero harmful blue light’ features, while the all-new Vidda C3 Ultra, set to debut in 2025, 
Today, we'll take a deep dive into the Vidda C3 Ultra to see what upgrades it has undergone.

Vidda C3 Ultra and Vidda C2 Ultra Core Parameter Comparison

 1.⚡️Core optical engine: Performance leap from MCL38 to MCL39

The vidda C2 Ultra is equipped with the MCL38 three-colour laser, which was the first of its kind in the world at the time. It has a measured brightness of 3000 CVIA lumens and a colour gamut that meets the BT.2020 standard, placing it among the top in the industry.
The vidda C3 Ultra takes it a step further with the world's first MCL39 cinema-grade three-colour laser module, boosting brightness to 3,200 CVIA lumens while achieving 110% BT.2020 colour gamut coverage and professional colour accuracy of ΔE<0.9.
This means that in complex scenes such as red sunsets or deep green forests, the C3 Ultra can reproduce more delicate and realistic colour gradients, rivaling professional displays.
Additionally, despite the increased brightness, the C3 Ultra maintains its high-efficiency design with excellent power consumption control.

2.Enhanced image quality with Dolby Vision support

The contrast ratio of the Vidda C3 ultra has jumped to 14000:1 (ultra dynamic), far exceeding that of the Vidda C2 ultra.
Full support for Dolby Vision has been added, making it one of its biggest highlights.

3.🎮 Performance and Intelligence: The Evolutionary Fusion of the MT9681 Chip and DeepSeek AI

Vidda C2 Ultra: Powered by the MT9679 chip + 4GB RAM, featuring automatic calibration, 240Hz high refresh rate, and WiFi 6
Vidda C3 Ultra: First to launch with the MT9681 ultra-flagship chip + 8GB RAM (128GB storage), offering faster performance, support for 4K UI interface, gigabit Ethernet port, and WiFi 7/Bluetooth 5.4
The larger RAM allows the C3 Ultra to handle multitasking, large games, and 4K video decoding with ease. It is also the first projector in the industry to pass Tencent START Cloud Gaming's 3-star certification, with game latency as low as milliseconds.

4.Sound Design: Structural Innovation from ‘Independent Bass’ to ‘Gimbal Subwoofer’

Both models feature Harman JBL custom audio systems and support Dolby Atmos, but the bass unit designs differ significantly:
Vidda C2 Ultra: The base integrates a 20W independent bass unit, with low-frequency extension down to 45Hz, delivering a powerful soundstage.
Vidda C3 Ultra: Pioneers a modular gimbal subwoofer design, featuring 2×10W high-frequency drivers + a 20W independent subwoofer, supporting Hi-Res lossless audio.

Conclusion:

Although the Vidda C3 Ultra outperforms the C2 Ultra in multiple aspects, this does not mean the latter is not worth considering. The C2 Ultra remains an extremely cost-effective true three-colour 4K laser projector, more than sufficient for everyday home cinema scenarios.
The Vidda C3 Ultra, however, represents a comprehensive upgrade, retaining and enhancing traditional strengths such as laser technology, professional-grade image quality, and bass design; but also introduces new features such as AI large models, Dolby Vision, cloud gaming ecosystems, and gigabit local decoding, positioning the C3 Ultra as a true next-generation smart audio-visual terminal, ideal for users with higher demands for image quality and ease of use.

The choice between the two models ultimately depends on your budget, usage environment, and personal preferences.
