7.9-inch ultrawide HDMI display works with Raspberry Pi SBC

If you are looking for an ultrawide display to show information on your PC or Raspberry Pi, there’s a 7.9-inch IPS display with 1280×400 resolution that may meet your requirements.

The display is powered through a USB port and takes a video source from its HDMI 1.4 input port, so it should work with any hardware equipped with HDMI output and a USB port.

7.9-inch ultrawide Raspberry Pi displayThe display can be purchased on Banggood for $63.99 including shipping. While looking for an alternative source, I also noticed Waveshare had a similar 7.9-inch display with touchscreen function going for $78.99 on their own website, or a little more on Amazon US. In this case, the USB connection is not only used for power, but also for the touchscreen function.
