Getting Started 2.1 Quick Start This quick start chart summarizes the basic setup and operation steps.
Overview 3 Overview The Kramer VA-1VGAN is a VGA EDID Capture, with VGA input and output on 15-pin HD computer graphics video connectors. When the VA1VGAN is connected to a display device and the CAPTURE EDID button is pressed, the VA-1VGAN reads and stores the EDID (Extended Display Identification Data) from the display device1. The display can be disconnected and later reconnected without rebooting the operating system.
Your VA-1VGAN EDID Capture 3.1 Defining EDID EDID (Extended Display Identification Data1) is a data-structure that the display provides to describe its capabilities to a graphics card connected to the display’s source. The EDID enables the source, such as a PC, to “know” what kind of monitor is connected to the output. The EDID includes: the name of the manufacturer, product type, timing data supported by the display, display size, luminance data, and (for digital displays only) the pixel mapping data.
Connecting the VA-1VGAN EDID Capture 5 Connecting the VA-1VGAN EDID Capture In the example illustrated in Figure 2, a projector is disconnected from a PC in order to reinstall it at a distance, after the PC has read the projector’s acquired EDID from the VA-1VGAN. The projector is then reconnected, without the need to reboot the system. The configuration illustrated in Figure 3 requires two separate stages: The VA-1VGAN needs to acquire the projector’s EDID information (see section 5.
Connecting the VA-1VGAN EDID Capture Figure 2: VA-1VGAN – Acquiring the EDID from the Display Device 5.2 Reconnecting the Projector To reconnect the projector at a distance from the PC, as illustrated in the example in Figure 3, do the following1: 1. Connect a VGA source (for example, a VGA computer graphics source) to the INPUT VGA connector on the VA-1VGAN. Turn on the VGA source only after connecting the VA-1VGAN, so it can acquire the EDID properly 2.
