SKU CH-46KJ-6PNA0

A DisplayPort dummy plug that emulates a 4K display at 17 Hz so headless systems can use GPU acceleration for remote desktop, mining, rendering and streaming

  • Enables GPU acceleration for remote desktop and rendering via virtual display emulation
  • Plug-and-play headless operation on Windows, macOS and Linux without drivers or external power
  • Supports 4K at 17Hz maximum resolution on any graphics card with DisplayPort output
  • Solves macOS headless display issues for stable remote access and server management
  • Compact adapter unlocks full GPU potential for mining, streaming, VR and headless server deployments

What this adapter does

The Fervit DisplayPort dummy plug emulates a connected monitor so the GPU stays active on headless systems. It presents a virtual 4K display at up to 17 Hz without drivers or external power. The plug-and-play dongle works on Windows, macOS and Linux.

Who it suits and who it does not

It suits operators of remote servers, mining rigs, render nodes or streaming boxes that run without a physical screen. It does not suit users who need higher refresh rates, multiple virtual displays, or EDID configurations beyond the single fixed profile this device provides.

The deciding specification

Maximum emulated resolution is 4K at 17 Hz over a DisplayPort connection. If your headless workload requires a faster refresh rate or a different video interface, this adapter will not meet that requirement.

Questions about this item

What does the 17 Hz limit mean when I use this plug for remote desktop?

The adapter reports a 4K virtual display at 17 Hz so the GPU stays active, but the remote session will refresh at that rate making fast motion appear choppy.

Does the DisplayPort connection need a specific DP version to work?

It plugs into any DisplayPort output and negotiates the link automatically; no particular DP revision is required.

How much space does the dongle need next to other ports on the graphics card?

The compact body sits flush against the port adding only a few millimetres of depth so it fits alongside adjacent connectors.
