A graphics processing unit (GPU) of a processing system transmits pixel data for a frame to a display in a compressed burst, so that the pixel data is communicated at a rate that is higher than the rate at which the display scans out the pixel data to refresh the frame at a display panel. By transmitting pixel data for the frame in a compressed burst, the GPU shortens the time spent transmitting the pixel data and extends the time before the next frame of pixel data is to be transmitted. During the extended time before the next frame of pixel data is to be transmitted, the GPU saves power by placing portions of the processing system in a reduced power mode.

Technology for a display source controller is described. The display source controller can receive display pixel data from a display source. The display source controller can convert the display pixel data to display symbol data that includes a plurality of 32-bit double words (DWords). The display source controller can divide the display symbol data that includes the plurality of 32-bit DWords for a number of unidirectional serial data channels. The display source controller can process, for each unidirectional serial data channel, the display symbol data at a 32-bit DWord granularity level. The display source controller can send the display symbol data for each of the unidirectional serial data channels over a physical serial link to a display panel.

A control system includes a plurality of driving circuits coupled in series, which include a first driving circuit and a second driving circuit. The first driving circuit includes a first receiver, a first transmitter and a first flag signal selector. The first transmitter is coupled to the first receiver, and the first flag signal selector is coupled between the first receiver and the first transmitter. The second driving circuit, coupled to the first driving circuit, includes a second receiver, a second transmitter and a second flag signal selector. The second transmitter is coupled to the second receiver, and the second flag signal selector is coupled between the second receiver and the second transmitter.

A system is disclosed for processing and streaming real-time graphics by a video-server for synchronized output via secondary-network connected display adapters to multiple displays arranged as a video-wall. This system enables the video-server to leverage performance advantages afforded by advanced GPUs, combined with low-cost Smart displays or System-on-Chip devices to deliver advanced realtime video-wall capabilities over the network while offering flexibility in the selection of network display adapters and still achieving synchronized output of multiple sub-image streams to selected end-point displays.
