EDID Management

Extended display identification data (EDID) is a communications protocol or instruction set for the identification of a monitor to a source computer that is using the DDC (Display Data Channel) transmission standard. EDID information consists of the native resolution, the vertical interval refresh rate, and pixel clock information about the connected monitor. After receiving this information, the source device outputs the optimal video format for the display based on the provided EDID data, ensuring proper video image quality.

When you are using the QGE 100 with DVI connections, the system manages the EDID differently, depending on whether or not a local monitor is connected.

QGE 100 connected with a local monitor

When the QGE 100 has a local monitor connected to its DVI Out (loop-out) connector, the highest resolution you are able to set on the connected PC is determined by that of the monitor.

In the example illustrated below, a computer capable of producing a UXGA (1600x1200) DVI-D output is connected to a QGE 100. Attached to the Out connector of the QGE is a flat panel LCD monitor capable of displaying signals up to SXGA (1280x1024).

In this case, the maximum resolution that the computer allows you to set is SXGA, because the EDID of the monitor has communicated with the graphics card and has designated SXGA as its maximum supported resolution. Therefore, the output of the computer is set to SXGA.

QGE 100 connected with no local monitor

When no local monitor is connected, the maximum resolution of the computer is selectable.

In the example illustrated below, a computer capable of producing a UXGA (1600x1200) DVI-D output is connected to a QGE 100. No monitor is attached to the DVI Out connector of the QGE.

In this case, the maximum resolution that the computer allows you to set is UXGA, because the EDID of the QGE 100 has communicated with the graphics card and designated UXGA as it maximum supported resolution. Therefore, the output of the computer is set to UXGA.
