Modular peripheral display power adapter power allocation and arbitration

A method for presentation of visual images at a peripheral display, the method comprising:

• coupling an external AC-to-DC adapter to a first DC cable port of the peripheral display to power presentation of the visual images at a display panel of the peripheral display;
• identifying a type of the AC-to-DC power adapter connected to the first DC cable port;
• applying the type to allocate power to the second DC cable port;
• and
• powering an external device with power provided from the second DC cable port.

A peripheral display comprising:

• an AC-to-DC power adapter, the AC-to-DC power adapter packaged to operate as an external power adapter with an AC cable plug port to accept an AC cable and a DC cable plug port to accept a DC cable;
• a display assembly having a display panel operable to present information as visual images, the display assembly having a processing resource and being interfaced with a first DC cable port to accept DC power from the AC-to-DC power adapter when external to the peripheral display and a second DC cable port to output DC power to an external device;
• and
• a non-transitory memory interfaced with the processing resource and storing instructions that when executed on the processing resource identify a type of the AC-to-DC power adapter connected to the first DC cable port and apply the type to allocate power to the second DC cable port.
