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.
