Using the Downstream EDID

By default, the (downstream) EDID from the display, connected to the Receiver unit, is used. If the internal EDID is being used (see Using the Internal DVI EDID), then use the following procedure to revert to the downstream EDID.

2.Click the Functions tab.

3.Make sure that the Copy EDID of Connected Display box is checked. This is the default setting. Click this box if it is not checked then click the Save button.

NOTE: Clicking the Load Internal EDID button, under the Sender unit, will override the status of the Copy EDID of Connected Display check box.

4.Click the Save button within the Video over IP group.

5.The following message will be displayed, at the top of the page, indicating that the new Serial over IP options have been applied.

6.Click the Reboot button at the bottom of the page.

7.The Sender unit will now use the EDID of the downstream sink device.
