Abstract
A multi-screen display control device is shown, which is linked to a host through a universal serial bus (USB) port to receive image data from the host, and uses a plurality of high-definition multimedia interface (HDMI) ports to output a plurality of HDMI sub-images to a plurality of screens. The multi-screen display control device has a USB hub that couples the USB port to a plurality of graphics processing units (GPUs), so that the GPUs generate the HDMI sub-images based on the image data transferred from the host via USB communication technology.
Claims19
A multi-screen display control device, comprising:
- a universal serial bus port, configured to link to a host to receive image data;
- a plurality of graphics processing units and a universal serial bus hub, wherein the universal serial bus hub couples the universal serial bus port to the graphics processing units, and the graphics processing units generate a plurality of high-definition multimedia interface sub-images based on the image data;
- and
- a plurality of high-definition multimedia interface ports, outputting the high-definition multimedia interface sub-images generated by the graphics processing units to a plurality of screens.
A multi-screen display control device, comprising:
- a plurality of cards;
- and
- a plurality of universal serial bus cables connecting the cards in series,
- wherein each card includes:
- a universal serial bus input port, receiving image data;
