Frequently Asked Questions

Q1: How do I connect two monitors? How many cables are needed?

✅ Each monitor needs to be connected separately:

• Full-featured USB-C laptop: 2 USB-C cables (video + power)

• HDMI device: 1 HDMI (video) + 1 USB-A/USB-C (power)

• Special solution: Use the included H5-T cable to convert a standard USB-A/USB-C to a video signal.

🎉 The S8ULTRA can connect two monitors with a single cable.

Q2: Is it compatible with Apple M1/M2/M3 chips?

🍎Yes! Using an H5-T cable can bypass Apple's single-screen limitations and achieve dual-screen expansion (using the H5-T cable requires additional power).

Q3: How to adjust dual screen mode (extended/mirrored)?

Control each screen mode independently in your computer's system settings (Windows: Win+P / Mac: Display Preferences).

Q4: Do you ship internationally? How long for delivery?

🌍 "Free global shipping via USP/FedEx. Delivery in 3-5 business days (US/EU) or 7-10 days (other regions).

The actual delivery time will be based on the actual logistics schedule! (Customs clearance may take some time. For more details, please contact us via WhatsApp: +86 19820581284.)

Q5: Is the screen scratch-resistant?

💎 The UV-treated surface resists daily wear, but we recommend using the included pouch during travel.
