Dynamic display resolution management for an immersed information handling system environment
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.
