Abstract

A remote access appliance is disclosed which provides electronic display identification data (EDID) information associated with a monitor which is communicating with the appliance, to any one of a plurality of remote computers in communication with the appliance, without requiring rebooting of a selected one of the remote computers. A plurality of multiplexers is controlled by a controller for interfacing a selected one of the computers to a display data channel (DDC) interface associated with the monitor. Memory devices are accessible by each of the computers and by the controller which store the EDID information. The controller controls the multiplexers so that any selected one of the computers can communicate with the monitor, and can access an associated one of the memory devices to obtain the stored EDID information, or such that the EDID information can be loaded into each of the memory devices.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 620,142, filed April 4, 2012, the entire contents of which are incorporated herein by reference. technical field [0003] The present application relates to a remote access device and method, and more specifically, to a remote access device capable of bidirectional communication with a monitor's Data Display Channel (DDC, Data Display Channel) interface, and the device also provides specific information on the device used. Non-volatile storage of extended display identification (EDID, Extended Display Identification) information related to the monitor. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] Today, data centers often utilize one or more remote access switches, sometimes referred to as "KVM" switches, to provide remote or server) to the ...
