EDID Minder

EDID Minder

EDID Minder ensures that the connected source sees the EDID of a display, even if a display is not connected. Depending on the EDID mode selected (by SIS command), the EDID of a connected display can be stored automatically, or the user can manually select from the table of factory loaded EDID files. This EDID is stored on an EEPROM located at the HDMI input.

By default, the HDMI DA2 is configured to store EDID from the display connected to output 1 automatically. The unit reverts to this configuration after a factory reset.

Automatic Mode

In automatic mode, the HDMI DA2 automatically reads and stores EDID from output 1 (a different output can be chosen using SIS commands). This EDID is retained until a different display is connected or the unit is power-cycled. If no display is connected when the unit is powered on, then a factory default EDID (720p @ 60 Hz, 2-Ch audio) is present.

User Assigned Mode

In user assigned mode, the user can select from 46 factory loaded EDID files, each catagorized by rate type (PC or HDTV), video format (DVI or HDMI), audio type (2-Ch or Multi-Ch), and native resolution. The unit retains this setting after a power cycle.

Additionally, four user-loaded slots are available to save the EDID of any connected display. EDIDs saved to these slots are retained after a power cycle. Upon a factory reset, these EDIDs revert to the factory default (720p @ 60 Hz, 2-Ch audio).

A table showing the factory loaded EDID options is shown on the following page. The EDID memory location is labelled X$ for consistency with the value in the SIS commands.

With its advanced signal processing capabilities, the DA2 ensures that the integrity of the signal is maintained, allowing for crystal-clear images and sound.

The DA2 is equipped with two HDMI outputs, allowing users to distribute a single HDMI source to two different displays simultaneously. Each output is capable of driving long cable runs—up to 50 feet for 4K signals—thanks to its robust signal amplification technology. This is especially beneficial in larger environments where displays may be located at significant distances from the source.

For added convenience, the Extron HDMI DA2 features EDID (Extended Display Identification Data) management, which allows the device to communicate effectively with connected displays. This ensures that the source and display can agree on the optimal video settings, enhancing compatibility and performance across diverse equipment.

Another notable characteristic is the automatic input switching feature, which allows the device to seamlessly switch between multiple HDMI sources if used in conjunction with other Extron products. This is particularly useful in situations where multiple devices may need to be accessed without the hassle of manual intervention.

The HDMI DA2 is also designed with ease of use in mind. It includes LED indicators that provide users with real-time feedback on power, input selection, and signal status. This streamlined approach helps in quickly diagnosing any issues that may arise during operation.

In terms of installation, the DA2 is compact and rack-mountable, making it a versatile choice for any AV system setup. With its rugged build quality and reliability, the Extron HDMI DA2 is tailored for professionals who demand high performance and dependability from their audio-visual equipment. Overall, this HDMI distribution amplifier is a critical component for any AV system requiring superior signal management for multiple displays.
