Adapts to Your Needs

Connect Two 4K or Full HD DisplaysThunderbolt Certified for Mac® and Windows(2), the Sonnet Thunderbolt 3 to Dual HDMI 2.0 Adapter supports two monitors at resolutions up to 3840 x 2160 (4K), but you can also use it to connect monitors with lower resolutions, like full HD 1080p (1920 x 1080) or 1920 x 1200 monitors. This makes it great for use for different home and office workspace applications. Because audio support is built in to the Sonnet adapter, you don’t have to plug in a separate cable to hear sound from the monitors. And, unlike USB adapters, the Sonnet adapter won’t drain system resources that might impact your computer’s performance.

Technical Notes

  1. Not compatible with USB-C only ports. Not all Thunderbolt 3 computers support dual displays or 60Hz refresh rates. Visit this web page and click the Filter by Brand/OEM link matching your computer, and then locate your computer model to determine its capabilities. Please note that at any given time this list may not be completely up to date. If your computer model is not listed, please contact the manufacturer for information.
  2. Windows computers require the latest firmware (BIOS) and other drivers to support this product. Check with your computer manufacturer for update information.
  3. EDID stands for Extended Display Identification Data. This is how the monitor identifies its resolution modes to the adapter. EDID Version 1.4 was finalized in 2006. If your HDMI monitor is more than 10 years old, it will likely not be supported.
