Abstract

A multi-monitor display is disclosed. A multi-monitor display receives a video data stream configured for a single H×V video display; splits the video data stream into a plurality of video data streams for transmission to a plurality of displays which, together, substantially span the H×V display.

Claims

1. A multi-monitor system, comprising:

a video receiver, the video receiver receiving a host video data stream appropriate for a video display of size H pixels by V rows;

a plurality of video transmitters, each of the plurality of video transmitters providing a video data stream to display a portion of the video data on each of a corresponding plurality of video displays; and

a splitter coupled between the video receiver and the plurality of video transmitters, the video receiver splitting the host video data stream from the video receiver into the video data stream for each of the plurality of video display to display the portions of the video data to each of the plurality of video transmitters,

wherein during the time that a first monitor of the plurality of video displays is receiving active video data, the remaining monitors of the plurality of video displays are in a blanking period.

2. The multi-monitor system of claim 1, wherein the video receiver is a DisplayPort compatible receiver.

3. The multi-monitor system of claim 1, wherein at least one of the plurality of video transmitters is a DisplayPort compatible transmitter.

4. The multi-monitor system of claim 1, wherein the portions are arranged horizontally.

5. The multi-monitor system of claim 1, wherein the portions are arranged vertically.

6. The multi-monitor system of claim 1, wherein the portions are arranged both vertically and horizontally.

7. The multi-monitor system of claim 4, wherein the portions of video data provided to each of the plurality of video transmitters has V rows, and the sum of the line pixels across each of the plurality of portions sums to H pixels.

8. The multi-monitor system of claim 5, wherein the portions of video data provided to each of the plurality of video transmitters has H pixels and the rows sum to V rows.

9. The multi-monitor system of claim 6, wherein the portions of video data provided to each of the plurality of vide transmitters sums to H pixels horizontally and V rows vertically.

10. A method of providing a multi-monitor display, comprising:

receiving a video data stream configured for a single video display of size H pixels by V rows;

splitting the video data stream into a plurality of data streams;

transmitting the plurality of data streams to a corresponding plurality of displays.

11. The method of claim 10, wherein receiving a video data stream includes receiving data according to the DisplayPort standard.

12. The method of claim 10, wherein transmitting the plurality of data streams includes transmitting data to each of the plurality of displays according to the DisplayPort standard.

13. The method of claim 10, wherein the plurality of displays are arranged horizontally and splitting the video data into a plurality of portions includes separating the H pixels of each of the V rows into a group of pixels for each of the plurality of displays.

14. The method of claim 13, wherein a sum of pixels across each of the group of pixels is H pixels.

15. The method of claim 10, wherein the plurality of displays are arranged vertically and splitting the video data into a plurality of portions includes separating the V rows of H pixels into a group of rows for each of the plurality of displays.

16. The method of claim 15, wherein a sum of rows across each of the group of rows is V TOWS.

17. The method of claim 10, wherein the plurality of displays are arranged in an array horizontally and vertically and splitting the video data into a plurality of portions includes separating the H pixels into pixel groups horizontally and separating the V rows into row groups vertically so that an appropriate portion of the vide data is displayed on a corresponding one of the plurality of displays.
