[0003] When used With a computer (for example), such SUMMARY kinds of display devices commonly have an OSD function. [0010] An exemplary on-screen display (OSD) system The OSD function is for displaying information relating to includes a display device and a computer connected to the adjusting of display characteristics of video signal transmit display device. The display device includes a micro process ted from the computer, as Well as information about the dis ing unit (MPU) con?gured for providing a plurality of play device itself. The display device and the computer coop instruction signals according to a user’s instructions. The eratively constitute an OSD system. The OSD activated on the computer includes a memory and a central processing unit screen of the display device generally includes an OSD menu (CPU). The memory includes an external OSD unit con?g for altering information associated With parameters of the ured for generating an external OSD menu. The external OSD display device. The OSD menu is typically composed of menu is colorfully and dynamically displayed. The CPU is single-colored characters, Which generally shoW the display con?gured for identifying the instruction signals from the parameters in the form of numerals Within ranges or in the MPU and providing control signals corresponding to the form of scale bars. Thus, the display device can achieve a instruction signals. The external OSD unit is capable of set preferred display performance by a user adjusting the settings ting and assigning data to generate the external OSD menu on of the display parameters via the OSD menu. receiving the control signals from the CPU, Whereupon the [0004] Referring to FIG. 4, a typical OSD system 1 external OSD menu is displayed by the display device. includes an inputting unit 10, a display screen 12, and a [0011] Other novel features and advantages Will become controlling circuit 14.
