EDID (Extended Display Identification Data)

EDID is the exchange of capabilities between a source and display. This handshake ensures the audio and video signals sent are supported by both source and display.

The AT-HD4-V41 has 3 EDID modes. Internal picks the highest common audio/visual signal between the devices and the available supported EDIDs within the switcher. External selects the highest common resolution between the current input and the display. Learned saves the EDID from the current display and locks it to the output.

When switching between EDID modes the unit will need to be power cycled. To power cycle the power cord will need to be unplugged and plugged back in.

Internal EDID

The Internally loaded EDID settings are the most common A/V signals that come standard in most TV displays and computer monitors. The AT-HD4-V41 will pick the highest common resolution between the devices.

External EDID

External EDID is the highest common audio/video signal between the current source device and display. It is useful for devices with uncommon resolutions that are not stored internally. When switching from internal to external EDID modes, press the EDID button so the external LED illuminates, then power cycle the unit. When the AT-HD4-V41 is turned back on it will sync with the display and determine the EDID.

Learned EDID

Learned EDID allows for a display’s EDID to be saved to the switcher’s nonvolatile memory. To learn the EDID from the display you first need to be in external EDID mode. Once you’re in external EDID, power cycle the unit then press and hold the EDID button until the red copy LED illuminates. Power cycle the AT-HD4-V41 again and the display’s EDID will be used.

AT-HD4-V41 specifications

The Atlona AT-HD4-V42 and AT-HD4-V41 are advanced HDMI distribution amplifiers designed to cater to the needs of professional AV environments. Both models offer robust solutions for distributing high-definition video signals over long distances without compromising quality.

The AT-HD4-V42 is equipped with four HDMI inputs and two HDMI outputs, allowing users to connect multiple HD sources to a single display or send signals to two separate displays. This flexibility makes it ideal for conference rooms, classrooms, and other environments where multiple sources need to be managed seamlessly. It supports resolutions up to 4K at 60Hz, ensuring that users experience crisp, clear, and vibrant visuals, even with demanding content.

One of the standout features of the AT-HD4-V42 is its advanced EDID management capabilities. By allowing users to control the Extended Display Identification Data (EDID) settings, it ensures that connected devices communicate effectively with one another for optimal performance. This is particularly important in setups where various HDMI sources and displays may have different specifications, as it helps prevent compatibility issues and ensures a smooth signal flow.

On the other hand, the AT-HD4-V41 offers a similar array of features but with a slightly different configuration. This model includes four HDMI inputs and one HDMI output, making it perfect for scenarios where only one display is required. Like its counterpart, the AT-HD4-V41 supports resolutions up to 4K, along with deep color and 3D pass-through capabilities, enhancing the viewing experience for users.

Both models are designed with ease of use in mind. They feature plug-and-play installation processes, enabling quick setups without extensive technical expertise. Additionally, these devices are built with robust aluminum enclosures for durability and thermal management, which are essential in maintaining performance over long hours of operation.

In conclusion, the Atlona AT-HD4-V42 and AT-HD4-V41 HDMI distribution amplifiers are exceptional tools for professional AV needs. Their support for high-resolution formats, advanced EDID management, and user-friendly design make them versatile solutions for any audio-visual setup. Whether in a corporate environment or educational facility, these devices provide reliable and high-quality signal distribution, catering to the demands of modern technology.
