1. What are the core technological advantages of the Vidda C3 Ultra?

The Vidda C3 Ultra is the world's first smart projector equipped with a MCL 39 three-colour laser, offering a brightness of 3200 CVIA (authoritatively certified, no exaggeration), supporting 110% BT.2020 ultra-wide colour gamut and ΔE<0.9 professional colour accuracy, with picture quality surpassing that of high-end OLED TVs. Combined with a 1.67x optical zoom lens, it can project a 100-inch lossless 4K image from 2 metres away, and meets six ‘zero-defect’ standards (zero colour difference, zero noise, zero harmful blue light, etc.).

2. Can I purchase an extended warranty for the projector?
Yes, we offer an official Vidda extended warranty service.

Purchase method: Please contact wuprobuy@wupro.com

Purchase timing: Within 11 months of purchasing the new unit, you may contact the original purchase channel to purchase extended warranty (based on the date on the invoice or electronic warranty card).

Coverage scope: During the extended warranty period, performance failures due to non-human damage (such as laser or optical lens failures) are eligible for free repair, but accidental damage (liquid ingress, drops, etc.) and accessories (remote control) are not included.

Recommendation: Since the C3 Ultra is a high-end model (priced at 11,999 yuan), repair costs are high, and extended warranty can reduce long-term usage risks.

3. Is a projection screen required to achieve optimal image quality?
Not mandatory. The C3 Ultra features wall colour adaptation technology, which automatically corrects colour deviations even when projecting directly onto a white wall. However, for cinema-level effects, we recommend using an anti-glare screen, especially in bright environments to enhance contrast.

4. Does the sound system require additional speakers?
No external speakers are needed. The C3 Ultra integrates a Harman JBL custom sound system (2×10W high-frequency units + 20W independent subwoofer), supporting Dolby Atmos and DTS decoding, with sound quality comparable to professional cinema equipment.

5. Is installation and calibration complicated?
Fully automated calibration:

One-click calibration: Achieves automatic focusing, trapezoidal correction, screen alignment, and obstacle avoidance via the Jingwei intelligent gimbal.

Flexible placement: The optical zoom lens supports side projection, enabling clear imaging without needing to face the wall directly.
