Abstract

An information handling system communicates visual information to a display in a first pixel value format and the display converts the first pixel formation to a native format with a graphics processing unit. The graphics processing unit adapts its programming to convert various input pixel values into desired native formats, such as by converting High Definition input into Ultra High Definition native format. The information handling system and display coordinate through configuration information to identify and program the display graphics processor to perform desired pixel conversion.

Claims (47)

1. An information handling system comprising:

a housing;

a processor disposed in the housing and operable to execute instructions to process information;

a memory disposed in the housing and interfaced with the processor, the memory operable to store the information;

a graphics processor disposed in the housing and interfaced with the processor and memory, the graphics processor operable to convert the visual information into pixel values having a first or second transport resolution for presentation as visual images at a display, the first and second transport resolutions different from each other;

a cable port interfaced with the graphics processor and operable to communicate the pixel values in the first or second transport resolutions to the display;

the display coupled to the cable port by a cable and presenting visual images in a native resolution;

a graphics processor unit integrated in the display and interfaced with the cable to accept the pixel values in the first transport resolution and to convert the pixel values to the native resolution;

a scalar integrated in the display and interfaced with the cable, the scalar operable to accept pixel values in the second transport resolution and to convert the pixel values to the native resolution; and

a timing controller interfaced with graphics processor unit and operable to forward the pixel values to pixels in the native resolution for presentation of the visual information as visual images;

wherein pixel values are communicated to the graphics processor unit if in the first transport resolution and communicated to the scalar if in the second transport resolution.

2. The information handling system of claim 1 wherein the first transport resolution comprises High Definition resolution and the native resolution comprises Ultra High Definition resolution.

3. The information handling system of claim 1 wherein the graphics processor of the housing and the graphics processor unit of the display communicate configuration information through the cable defining the first transport resolution and native resolution.

4. The information handling system of claim 1 wherein the graphics processor of the housing communicates a conversion algorithm to the graphics processor unit of the display, the graphics processor unit of the display applying the conversion algorithm to convert the pixel values.

5. The information handling system of claim 4 wherein the graphics processor of the housing retrieves the conversion algorithm from a network location.

6. The information handling system of claim 1 wherein the graphics processor of the housing has plural transport resolution formats available to send the pixel information, the graphics processor of the housing selecting one of the plural transport resolution formats to use as a transport resolution based upon capabilities retrieved from the graphics processor unit of the display.

7. The information handling system of claim 6 wherein the graphics processor of the housing selects the transport resolution based upon capabilities retrieved from the scalar.

8. A method for presenting visual images at a display having a native resolution with visual information received from an information handling system, the method comprising:

generating pixel values at graphics processor of the information handling in one of a first or second transport resolution, the first and second transport resolutions different from each other;

communicating the pixel values to the display in the one of the first or second transport resolutions;

if the pixel values are in the first transport resolution, receiving the pixel values at a graphics processor integrated in the display;

if the pixel values are in the second transport resolution, receiving the pixel values at a scalar integrated in the display;

converting the pixel values received at the graphics processor with the graphics processor from the first transport resolution to the native resolution;

converting the pixel values received at the scalar with the scalar from the second transport resolution to the native resolution; and

presenting the visual information at the display with the pixel values in the native resolution.

9. The method of claim 8 wherein the first transport resolution comprises High Definition and the second transport resolution comprises Ultra High Definition.

10. The method of claim 8 further comprising:

communicating a conversion algorithm from the information handling system to the graphics processor of the display;

programming the graphics processor of the display with the conversion algorithm; and

converting the pixel values with the conversion algorithm.

11. The method of claim 10 wherein communicating a conversion algorithm is performed in response to the display communicating incompatibility with the first transport resolution, and the conversion algorithm converts from the first transport resolution to the native resolution.

12. The method of claim 8 further comprising:

exchanging configuration information between the information handling system and display;

applying the configuration information at the information handling system to select the first transport resolution from plural transport resolutions based upon conversion capabilities of the display in the configuration information.

13. The method of claim 12 further comprising:

selecting the first transport resolution for compatibility with the scalar; and

selecting the first transport resolution for compatibility with conversion algorithm programmed on the graphics processor of the display if a scalar is not available on the display.

14. The method of claim 13 further comprising:

selecting the first transport resolution for compatibility with a programmable conversion algorithm if the graphics processor does not have a compatible conversion algorithm; and

communicating the programmable conversion algorithm from the information handling system to the display to program the graphics processor of the display.

15. The display of claim 14 wherein the native resolution comprise Ultra High Definition and the plural different transport resolutions comprises High Definition.

16. The display of claim 14 wherein the graphics processor accepts a conversion algorithm from the external pixel source and applies the conversion algorithm to convert pixel values from the selected of the transport resolutions to the native resolution.

17. A display comprising:

pixels that present a visual image at a native resolution;

a timing controller interfaced with the pixels and operable to forward pixel values to the pixels in the native resolution that define the visual image, the pixel values received through a cable and having a selected of plural different transport resolutions;

a graphics processor interfaced with the timing controller and an external pixel value source, the external pixel source providing the pixel values in a first of the plural different transport resolutions, the graphics processor programmed to execute a conversion algorithm that converts the pixel values from the first of the plural different transport resolutions to the native resolution; and

a scalar that converts a second of the plural different transport resolutions received from the external pixel source to the native resolution.
