Abstract

A display device presents visual information with native and non-native resolutions stored in EDID and provided to a graphics controller. Non-native resolutions are generated in response to an object detected that interferes with the presenting of the visual information, such as an object between a projector and projection surface or an object placed on a capacitive mat display. The non-native resolutions present the visual information to avoid the object and are stored in EDID in association with object characteristics to allow re-use of the non-native resolutions when visual information at the display is blocked by an object with similar characteristics.

Claims

1. An information handling system comprising:

a processor operable to process information for presentation to a user as visual images;

memory interfaced with the processor and operable to store the information;

a graphics system interfaced with the processor and memory, the graphics system operable to generate the visual images at one or more display devices;

a display device interfaced with the graphics system and operable to present the visual images at a display area, the display device storing extended display identification data (EDID) that defines display device performance characteristics including at least one pre-existing EDID having a native resolution of the display device;

a resolution engine associated with the graphics system and operable to retrieve the EDID from the display device and apply the EDID to format the visual information as pixel values compatible with the display device; and

one or more sensors interfaced with the processor and operable to sense one or more conditions proximate the display device, the one or more conditions including at least an object disposed on the display device;

a resolution mapping engine interfaced with the one or more sensors;

wherein the resolution engine responds to one or more sensed conditions by defining a new non-native resolution having non-standard timing for presentation of information by the display device at less than all of the display area, storing the non-native resolution in EDID of the display device in association with the one or more sensed conditions, and applying the non-native resolution to present visual information as pixel values, the pixel values adapting the visual information to compensate for the one or more sensed conditions;

wherein the resolution engine defines non-native resolutions having non-standard timing by defining at least some pixel values to have black values and translating content to pixels other than those with black values; and

wherein the resolution mapping engine detects the one or more sensed conditions and compares the one or more sensed conditions stored in association with non-native resolutions to identify and apply in response to the one or more sensed conditions.

2. The information handling system of claim 1 wherein the one or more sensed conditions comprises an object detected in an image captured by a camera, the object place on a portion of the visual images presented by the display device.

3. The information handling system of claim 2 wherein the display device comprises a projector aligned to project visual images at a desktop and object comprises an object placed on the desktop in projection area of the projector.

4. The information handling system of claim 1 wherein one or more sensed conditions comprises an object detected on a capacitive mat by a capacitive touch sensor disposed in the capacitive mat.
