Abstract
An information handling system sends plural display image streams through a single display cable to a display for presentation as plural display images at plural partitions. A multi stream hub integrated in the display receives the display cable information and sends each display stream out a source channel of the multi stream hub to a receive channel of the display controller. The display controller blends the received display information to present display images at the display panel with the display images partitioned by receive channel.
Claims20
An information handling system comprising:
- a housing;
- a central processor unit disposed in the housing and operable to process instructions to generate visual information;
- a memory interfaced with the processor and operable to store the visual information;
- a graphics processing unit interfaced with the central processor unit and operable to process the visual information to output pixel values that define visual images at one or more displays and communicate visual images to plural separate displays through a single display cable;
- and
- a peripheral display having a display panel with plural pixels that present a visual image from the pixel values, the peripheral display having a display cable port interfaced with a multi-stream hub, the multi-stream hub interfaced with a display controller and integrated in the peripheral display, the display controller interfaced with the display panel, the multi-stream hub communicating pixel values as plural source channels to plural receiver channels of the display controller, each source channel having visual images of one of the plural separate displays, each receiver channel presenting one of the plural separate displays in an associated defined portion of the display panel.
A method for presenting visual images from an information handling system at a display, the method comprising:
- defining plural source channels at a multi-stream hub integrated in the display;
- linking a graphics processing unit of the information handling system to the multi-stream hub through a single display cable, the graphics processing unit communicating display visual images for plural separate displays through the single cable;
- communicating from the graphics processing unit through the single cable to the multi-stream hub the plural display visual images for each of the plural displays through each of the plural source channels;
- communicating each display image to a receiver channel of a display controller interfaced with the multi-stream hub;
- and
- blending the display images at the display controller to a single output presented at a display panel of the display.
A display comprising:
- a display panel having plural pixels that present a visual image;
- a controller interfaced with the plural pixels to scan pixel values that define the visual image to the pixels;
- a multi-stream hub integrated in the display and having plural source channels interfaced with plural receive channels of the controller, each source channel associated with one of plural displays communicated by a graphics controller, each of the displays having a display visual image;
- and
- a display cable port interfaced with the multi-stream hub, the multi-stream hub receiving plural display image streams from the display cable port, each of the plural display image streams associated with one of the plural display visual images, and providing each display image stream from one of the source channels to one of the receive channels, the controller blending the display image streams for presentation of the plural display visual images at each of plural partitions defined at the display panel.
