Fervit DisplayPort Dummy Plug 4K@17Hz LED Blue

SKU CH-GC90-7HSCF

A DisplayPort dummy plug with a blue LED that emulates a 4K@17Hz display for headless GPU operation

  • LED indicator shows real-time status
  • Emulates 4K display at 17 Hz for headless GPU operation
  • Works with any graphics card that has DisplayPort output
  • Plug-and-play on Windows, macOS and Linux without drivers
  • Enables remote desktop, mining, rendering and game streaming headless

Fervit DisplayPort Dummy Plug 4K@17Hz

The Fervit DisplayPort dummy plug emulates a connected monitor so a system can run headless while keeping the GPU active. It supports a maximum resolution of 4K at 17Hz and draws power directly from the DisplayPort output. A built-in blue LED indicates the link status in real time. The adapter works plug-and-play on Windows, macOS and Linux without any driver installation.

Suits headless servers and remote GPU workloads

This adapter suits administrators running remote-desktop sessions, rendering farms, mining rigs or streaming boxes that need the GPU enabled without a physical display. It also resolves the macOS headless restriction that otherwise disables hardware acceleration. Buyers who require higher refresh rates or resolutions beyond 4K at 17Hz should look at an active emulator or a real monitor instead.

Maximum emulated resolution 4K at 17Hz

The single specification that decides suitability is the maximum emulated resolution of 4K at 17Hz. If the target application demands a higher refresh rate or a higher pixel count, this plug will not satisfy the requirement. For workloads that only need the GPU to initialise at standard 4K resolution, the limit is adequate.

Questions about this item

Will the LED on the Fervit dummy plug need replacing after continuous use?

The LED is built into the adapter and draws power from the DisplayPort connection; no separate bulb or battery is fitted, so there is no user-replaceable part.

What resolution and refresh-rate ceiling does the adapter enforce during long rendering or mining sessions?

The plug reports a maximum of 4K at 17 Hz to the GPU, and that limit remains fixed regardless of workload duration.

Does the adapter produce any audible noise or noticeable warmth when powered all day?

It has no fan or moving parts and draws only the small DisplayPort auxiliary current, so it runs silently and stays at ambient temperature.
