A Personal Computer accessory that turns a single USB-C port into multiple HDMI outputs for multi-monitor working and presentations. Organised workflows and clearer screen real estate help remote workers and students stay on top of tasks. Is the Oliveria USB C Dual HDMI Adapter the right choice for portable multi-screen setups?

⚡ At a Glance
  • Display Support: Single HDMI up to 4K@60Hz, dual HDMI simultaneous up to 4K@30Hz
  • Best for: Professionals and students needing portable dual-monitor productivity
  • Not ideal for: Users expecting extended multi-screen support from all tablets or phones

USB-C or Thunderbolt 3 outputs using DisplayPort Alternate Mode handle video transmission. Windows systems can use SST and MST for expanded desktops while some other systems mirror screens.


Effortless Multi-tasking – With Dual HDMI that supports 4K output

Dual HDMI outputs accept HDMI cables and use a USB-C connection that supports DisplayPort Alternate Mode; a single HDMI can reach 4K@60Hz while both HDMI ports together reach up to 4K@30Hz. Windows hosts that support SST and MST can extend different images across screens, while some other operating systems will mirror displays.

Set up two external screens for spreadsheets, browser windows and video calls to reduce alt-tabbing and improve focus. Ideal for connecting to TVs, projectors or monitors for both work and presentations.

Keep Laptops Powered – Thanks to PD 100W passthrough

Power delivery up to 100W travels through the USB-C PD channel while video signals pass via DisplayPort Alternate Mode, so power and display signals coexist on the same connection. A suitable USB-C power supply and cable are required for full PD performance.

Run dual external displays while charging a laptop, avoiding battery drain during long work sessions. Useful for portable setups where a single charger must support laptop and peripherals.

Stable Signal and Durable Build – With anti-interference PCB and aluminium shell

An internal PCB design reduces electromagnetic interference and an aluminium shell improves heat dissipation and resistance to wear. No driver installation is required for plug-and-play operation on supported systems.

Expect fewer dropouts and more reliable connections during extended use, and a compact unit that tolerates daily travel. Plugging in monitors first then the host helps ensure the expected display order and audio routing.
