USB-C EDID Detective for 8K Workspaces

The Gefen GF-EDD-UC is a USB-C EDID detective that captures and stores a display's EDID so the source maintains a stable video link even when the monitor is unplugged or switched away. It supports USB-C Alt Mode video up to 7680 x 4320 at 30 Hz and 2160p at 60 Hz with HDR10, Dolby Vision and HLG. The device protects content with HDCP 2.3 and delivers 32.4 Gbps bandwidth for conference rooms, classrooms and hybrid workspaces.

8K@30 Hz and 4K@60 Hz via USB-C Alt Mode

The single specification that decides fit is the maximum supported video mode over USB-C Alt Mode: 7680 x 4320 at 30 Hz and 2160p at 60 Hz with 32.4 Gbps HBR3 bandwidth. If your source or display requires higher refresh rates at 8K, or a different video interface altogether, this unit will not meet that requirement.

Ideal for AV integrators and hybrid-work IT teams

Suits integrators who need persistent EDID emulation for docking stations, digital signage, media players and workstations that regularly lose the display handshake. Not for users who need capture or recording functions, multi-input switching, or support for video interfaces other than USB-C Alt Mode.

Questions about this item

What does the 8K@30 Hz figure mean when the device is connected to a workstation?

It means the unit can capture and replay a display EDID that supports 7680 x 4320 resolution at 30 Hz so the source keeps sending that signal even if the monitor is unplugged.

How does the USB-C Alt Mode interface limit the video bandwidth in practice?

The USB-C Alt Mode link is capped at 32.4 Gbps HBR3 bandwidth which carries 8K@30 Hz or 4K@60 Hz with HDR10, Dolby Vision and HLG.

What physical connection does the detective need to sit between the source and the display?

It plugs inline on the USB-C cable between the host and the monitor so it can intercept and store the EDID handshake.
