Deliver Time

  • Once your order has been handed over to the carrier for delivery, you will receive a shipment notification email with an estimated delivery date. Please note that it is not possible to expedite your delivery and receive your package earlier than the scheduled delivery date. Therefore, we are unable to accept requests for expedited delivery. Our carriers are unable to provide an exact time of day for your delivery. If you ordered multiple items, you may receive separate shipments.
  • All estimates are based on business days. We only make deliveries in the specified areas of Hong Kong from Monday to Sunday except on the first two days of the Lunar New Year and when typhoon warning signal No. 8 or above or black rainstorm warning is in force.
  • All rescheduling of delivery, additional purchases, new sales memos and amendments must be made 3 days before the scheduled delivery date. Otherwise, a double delivery charge will be incurred.
  • We may deliver the merchandise in one or more installments, and some of the merchandises may be delivered directly from suppliers. Any times and dates given for dispatch of merchandise, or the length of time that merchandise will take to be delivered, are only estimates. If we are unable to meet any stated dispatch or delivery dates or times we will inform you as to the progress of your order. You agree and accept that under no circumstances will we accept cancellation of order or refund.

Signature On Delivery

  • Most of our shipments contain valuable items. If you will not be in attendance to accept delivery of your purchase, consider shipping to someone you trust will be able to sign for your package. For your convenience, you may prefer to have your order delivered to your office address. If you choose this option, please include the name of your business in the address. Please note, if you choose this option, goods may be left with reception or the Mail Room.
  • As our carriers require a signature on delivery, the carrier will leave a calling card if you are not at home. Please contact the carrier to reschedule delivery.
  • For postal deliveries, no signature is required and order status tracking is not available.
  • Delivery failure due to no one answering the door upon the arrival of goods at the appointed time, or to circumstantial limitations such as the entrance being too small, will require a rescheduled delivery and therefore incur double delivery charges.
  • We will deliver the merchandise ordered by you to the address you give us for delivery at the time you make your order through our staff or a third party provider. You agree to present your photo identification upon request when you acknowledge receipt of the merchandise. The merchandise shall be, and shall be deemed to be, delivered and accepted by you when the merchandise are delivered to the address you give us for delivery.

Thunderbolt Dual HDMI Adapter for Intel, M1 Pro, M1 Max, M1 Ultra Mac and Intel Windows Computers

Sonnet’s Thunderbolt™ Dual HDMI® Adapter enables you to work more efficiently with monitors attached to your notebook or all-in-one computer, enabling you to connect two 4K (3840 x 2160) @ 60 Hz HDMI displays to a single Thunderbolt 4 or Thunderbolt 3 port on your computer.

Productivity Partner – Expanded Workspace, Enhanced Workflow

Work more efficiently and expand your application desktop space across multiple screens. Whether you need to edit video or code like a pro, open multiple applications on their own screens, crunch spreadsheets in detail, or mirror your notebook’s display on a larger monitor, the Sonnet Thunderbolt Dual HDMI Adapter makes it possible. Connecting the adapter is plug-and-play easy – your computer powers the Sonnet adapter, so there’s no need to connect an additional power supply, and with native macOS® and Windows® support there’s no need to install separate driver software.

Go Big, Go Full Screen – Enjoy the Web and Videos at a Distance

Even when you’re not using productivity software, your notebook’s screen can constrain your view. Go big—the Sonnet Thunderbolt Dual HDMI Adapter enables you to connect your computer to your large monitor or big screen TV to browse the web and watch videos on YouTube and other content at a distance.

Not Just for 4K Displays – Supports Full HD (1080p) Displays and Audio Out

While the Sonnet Thunderbolt to Dual HDMI Adapter supports two monitors at up to 4K resolutions (3840 x 2160), you can also use it to connect monitors with lower resolutions, like full HD 1080p (1920 x 1080) @ 60Hz—this makes it great for use for different home and work applications. Because audio support is built into the Sonnet adapter, you don’t have to plug in a separate cable to hear sound from connected displays.

Optimal HDMI Video Performance Over Thunderbolt

Sonnet's Thunderbolt Dual HDMI Adapter is compatible with Intel, M1 Pro, M1 Max Mac and Windows 11 or 10 Thunderbolt computers. Thunderbolt's 40Gbps interface lets you run Ultra HD 4K resolution at 60 Hz on both displays at full performance.
