VEF-FHH-110
HDMI Emulator, EDID Copy, EDID Emulation
The VEF-FHH-110 is an HDMI EDID Emulator that can store and copy EDID information from a display device and present it to a source device. EDID is a set of data that informs the source device about the connected display, including its name, size, colour capabilities, and supported resolutions. This allows the source device to adjust its output to match the display and deliver optimal video quality.
If the display device’s EDID is unavailable or incorrect, the VEF-FHH-110 can provide either a default or a copied EDID. The device also supports HDCP pass-through, allowing it to handle encrypted content from the source device without modification.
EDID Feeder: EDID Emulator (DDC Ghost)
This HDMI emulator supports two EDID functions: EDID Auto Learning and EDID Copy. These functions allow the device to read and store EDID information from an EDID-compliant monitor or projector, ensuring accurate display output. The device supports EDID feeds from HDMI-compliant displays and offers both Permanent (EDID Copy) and Temporary (EDID Auto Learning) EDID configurations.
Note: EDID Auto Learning records the EDID information temporarily; the stored EDID data will be erased after a hot plug event or when the device is powered off.
When is it appropriate to use the EDID simulation function?
Bridging: When the EDID signal cannot be fully communicated between the AV source (PC or DVD player) and the AV display devices (monitor, projector, extender, switcher, or splitter) due to system limitations or signal interruption, an EDID emulator intervenes to establish proper EDID communication.
Set Screen Resolution (Limiter): Prevents the AV source from outputting resolutions that exceed the capabilities of downstream display devices or the overall AV system.
System Startup: Front-end devices such as PCs or media players may fail to boot or play video normally when no display is detected. EDID simulation emulates a connected display, allowing the source devices to complete normal startup and operation without requiring a physical monitor.
Engineering Test: High-end displays or projectors are costly, and EDID compliance testing typically requires multiple displays and repeated cable connections. The EDID simulation function eliminates frequent plugging and unplugging, avoids moving bulky monitors, and significantly reduces testing time and cost.
