    摘要: Circuits, methods, and apparatus that allow a DisplayPort compatible host device to control data transactions over an I2C bus when communicating with a legacy monitor. One example includes an adapter having a compatibility register that may have a number of locations, where at least some of the locations correspond to I2C bus speeds. Values stored at these locations can indicate whether the adapter is compatible or incompatible with the corresponding I2C bus speed. Another example includes an adapter having a speed register that may have a number of locations, where at least some of the locations correspond to I2C bus speeds. A defined value written to one of these locations dictates the corresponding I2C bus speed.

    摘要: Circuits, methods, and apparatus for registers to store information that may be used by devices in a display system. One example provides control and data registers in a display to store information pertaining to a display system that includes the display. The registers can store attributes of the display, a host device, and a branch device. The information may include an organizationally unique identifier, chip identification, major and minor chip revision information, and firmware major and minor revision information.

    摘要: Circuits, methods, and apparatus that allow a host to determine the capabilities of a new display that has replaced a previous display in a display system. In one example, a host determines capabilities of a new display after the host exits a sleep state. After exiting the sleep state, the host wakes an adapter. The adapter determines the presence of a display and sends a hot-plug detect interrupt signal to the host. Following this, the host reads information stored in the display and determines whether the adapter has been connected to a new display. If the adapter is connected to a new display, the host reads capabilities such as supported resolutions and refresh rates from the display and make adjustments to graphics output data as necessary.
