The StarTech USB32HD4K is a USB 3.0 (USB-A) to HDMI adapter with a DisplayLink chip that adds a 4K video output at 30 Hz to any PC, compatible with Windows, macOS, ChromeOS and Linux, without using up a graphics-card output.
It works as an external USB graphics card: connect an HDMI monitor, TV or projector to a free USB-A port and the system recognises it as an extra display to extend or mirror your desktop. In a racing simulator it is the practical way to add an auxiliary screen for a telemetry dashboard when your graphics-card outputs are already taken by the triple or ultrawide setup.
Key features of the StarTech USB32HD4K
- HDMI output up to 4K UHD (3840 × 2160) at 30 Hz; 1080p at 60 Hz and ultrawide 3440 × 1440 support.
- DisplayLink chip with 4K Plug-and-Display certification: on Windows with an internet connection it installs the driver automatically.
- Compatible with Windows, macOS, ChromeOS and Linux, regardless of the computer's graphics card.
- Extend or mirror modes to expand or clone your main desktop.
- 5.1 audio over HDMI and HDCP 2.2 support for protected content.
- Powered by the USB bus itself, no external power supply; USB-A male to HDMI female connector.
