Abstract
Apparatus, and an associated method, selects parameters determinative of video display characteristics of video displays displayable upon a video monitor. The parameters, such as brightness and contrast parameters, are stored at the video display monitor. The video display monitor is connected to a computer system unit. During booting operations, the video display parameters are retrieved by the computer system unit and selectably used to determine the video display characteristics of video displays displayable upon the video display monitor.
Claims16
In a system having a computer system unit and a video display monitor connectable to the computer system unit, an apparatus for alternately selecting a first video display parameter and a second video display parameter, said apparatus comprising:
- video display parameter storage device positioned at the video display monitor, said video display parameter storage device for storing the first video display parameter and the second video display parameter thereat, the first and second video display parameters stored at said video display parameter storage device accessible by the computer system unit;
- a convergent device alternately operable in a computer operational mode and in a non-computer operational mode;
- and
- a comparator coupled to receive an indication of the first video display parameter stored at said video display parameter storage device and accesible by the computer unit, said comparator for comparing a value of the indication of the first video display parameter with at least one threshold value, the video display parameter selected to be used to determine at least one characteristic of the video display if the value of the first video display Parameter is in a selected relationship with the threshold value,
- wherein the video display monitor is operable to display a first image according to the first video display parameter responsive to the convergent device operating in the computer operational node, and wherein the video display monitor is operable to display a second image according to the second video display parameter responsive to the convergent device operating in the non-computer mode.
The apparatus of claim wherein said comparator is positioned at said computer system unit.
A method for alternately selecting a first or a second video display parameter responsive to a convergence device being in either a first operational mode or a second operational mode, the first and the second video display parameter each determinative of at least one characteristic of a video display displayable upon a video display monitor, the video display monitor connectable to a computer system unit of a computer system, said method comprising the steps of:
- storing the first video display parameter at the video display monitor;
- storing the second video display parameter at the video display monitor;
- responsive to the convergence device being in the first operational mode, retrieving the first video display parameter, stored during said step of storing the first video display parameter, from the video display monitor;
- responsive to the convergence device being in the first operational mode, configuring the video display monitor to be operable according to the first video display parameter associated with the at least one characteristic;
- comparing the first video dislay parameter retrieved during said step of retrieving the first video display parameter with at least one threshold value and determining the at least one characteristic of the video display when the first video display parameter is of a value in a selected relationship with the threshold value;
- responsive to the convergence device being in the second operational mode, retrieving the second video display parameter, stored during said step of storing the video display parameter, from the video display monitor;
- and
- responsive to the convergence device being in the second operational mode, configuring the video display monitor to be operable according to the second video display parameter associated with the at least one characteristic;
- wherein the at least one characteristic associated with the first video display parameter and the second video display parameter includes one of brightness, contrast, horizontal positioning, vertical positioning, horizontal size, vertical size, tilt, audio and color.
A computer system comprising:
- a display device alternately operable according to a first display parameter and according to a second display parameter;
- a storage device integrated with the display device, the storage device for storing the first display parameter and the second display parameter;
- a convergence device connected to the display device, the convergence device operable in a computer functionality mode and a non-computer functionality mode;
- and
- a comparator coupled to receive an indication of the first display parameter, said comparator for comparing a value of the indication of the first parameter with at least one threshold value, the first display parameter selected to be used to determine at least one characteristic of the display device if the value of the first display parameter is in a selected relationship with the threshold value,
- wherein the display device is operable according to the first display parameter stored on the storage device when the convergence device is in the computer functionality mode and wherein the display device is operable according to the second display parameter stored on the storage device when the convergence device is in the non-computer functionality mode.
