Abstract
An electronic device with a connector supporting multiple connection standards includes the connector, a processor, a controller, an EDID (Extended Display Identification Data) ROM, a first multiplexer circuit and a second multiplexer circuit. The first multiplexer circuit is coupled to at least one signal pin of the connector, the processor and the controller. The second multiplexer circuit is coupled to the EDID ROM, the first multiplexer circuit, the processor and the controller. Under an update state, the controller is electrically connected to the EDID ROM through the second multiplexer circuit, and updates EDID in the EDID ROM with update data.

An electronic device with a connector supporting multiple connection standards, comprising:
- the connector, comprising at least one signal pin;
- a processor;
- a controller, coupled to the processor;
- an Extended Display Identification Data (EDID) read-only memory (ROM), for storing EDID;
- a first multiplexer circuit, coupled to the at least one signal pin, the processor and the controller;
- and
- a second multiplexer circuit, coupled to the EDID ROM, the first multiplexer circuit, the processor and the controller;
- wherein in an update state, the controller is electrically connected to the EDID ROM through the second multiplexer circuit, and updates EDID ROM with respect to EDID therein using update data through the second multiplexer circuit.
An update method for an electronic device with a connector supporting multiple connection standards, the connector, comprising at least one signal pin, the electronic device comprising a processor, a controller, coupled to the processor, an Extended Display Identification Data (EDID) read-only memory (ROM), for storing EDID, a first multiplexer circuit, coupled to the at least one signal pin, the processor and the controller, and a second multiplexer circuit, coupled to the EDID ROM, the first multiplexer circuit, the processor and the controller, the update method comprising:
- in an update state, updating the Extended Display Identification Data (EDID) read-only memory (ROM) using update data by the controller through the second multiplexer circuit.
