Video: EDID Management - With Connected Display or Projector

Last updated 6 August 2026

Steps

Left alone, a GPU output takes its timing from whatever the connected display advertises. That is convenient and it is fragile: swap a projector, lose a signal at power-on, or put a splitter in the chain, and the output can come back at a different resolution — or not come back at all.

Emulating the EDID in the GPU removes that dependency. The output then presents a fixed, known timing regardless of what is plugged in. This page builds that EDID from the display you already have connected, which is the best possible starting point because it is guaranteed to be a mode the device really supports.

Before you start

  • The display or projector you want to copy must be connected and detected on a GPU output.

  • Sign in as Admin. The GPU section is admin-only.

  • Know the frame rate of the media you will play. It decides the refresh rate you build into the EDID.

  • Outputs that are part of a mosaic, or removed from the desktop, are locked here. Return them to the desktop or clear the mosaic first.

1. Open the server's EDID page

In the Hub, select the server and click System Management to open its Web Console.

Under Configure, choose GPU, then the EDID tab. Everything to do with EDIDs — and every other GPU action — lives in this section.

2. Read the current state of the outputs

EDID override per output lists every output on every GPU, with the display's own name beside it and its Current source. A freshly configured server reads Default · Default on all of them, meaning the output is using the monitor's own EDID and nothing is being emulated.

That is the state this procedure replaces.

3. Import the EDID from the connected display

In the EDID editor panel, pick the output whose display you want to copy from the dropdown, then click Import from display. The other two routes — Import from file (.bin) and Create generic (generator) — build an EDID from a saved file or from scratch instead.

The editor reports what it read — the display's name, the EDID size, and how many modes it found — and lists them all under Modes to keep.

4. Keep only the mode you actually want

A real display advertises a lot of modes. This one offered fifteen. You almost never want to carry them all forward: the point of emulation is that the output presents one known timing.

Untick everything except the mode you are standardising on. In the video that means keeping the 3840x2160 @60.00Hz base DTD and unticking the 30 Hz one.

The VIC entries are HDMI modes — ignore them on a DisplayPort link. They make up most of the list and none of them apply when the display is connected over DisplayPort, which is why the video passes over them without unticking each one.

5. Fix the refresh rate

Displays quite often report a slightly imperfect refresh rate. Tick Override base DTD rate under Options and type the rate you want into Rate (Hz) — the mode keeps its resolution and gets the clean figure.

Pick the rate from your media, not from the display. The output frequency should be equal to the media frame rate or an exact multiple of it. 60 Hz carries both 60 and 30 fps content cleanly; choosing 50 Hz for 60 fps material guarantees judder no amount of playback tuning will fix.

6. Preview and save it to a slot

Click Preview EDID to build the EDID from your selection, give it a name, and Save to slot. Use a name that describes the timing — UHD_60 — because that name is what you will see against every output later.

Saved EDIDs appear under Saved EDID slots, where they can also be downloaded or deleted. Saving does not change any output — it only makes the EDID available to assign.

7. Assign the slot to the outputs

Back in EDID override per output, choose the saved slot from the Assign EDID dropdown for each output that should use it, then click Apply on that row. Apply all pushes the selection to every output at once, which is what you want when the whole GPU should present the same timing.

Loading an EDID onto the outputs takes a while, and the displays will re-sync while it happens. Outputs drop and come back as the GPU re-reads the forced EDID. Do not do this during a show, and let the page finish before judging the result.

Done when

Every output you assigned reads File (Forced) with your EDID's name as its Current source, and the output names themselves change from the display's model to your EDID's name — DisplayPort(4) DP UHD_60 rather than DisplayPort(4) DP ASUS VP28U. That rename is the visible proof the emulation took: the GPU is no longer reading the monitor.

To go back to the display's own EDID, use Clear override on a single output or Clear all override for every one.

What this depends on

Depends on

Why

A connected, detected display

Import from display reads the EDID off the device. Without it, build a generic EDID instead.

The media frame rate

Determines the refresh rate you build in — equal to, or an exact multiple of, the content.

Outputs on the desktop, not in a mosaic

Mosaic members and outputs removed from the desktop are locked against EDID changes.

Admin role

The GPU section is admin-only.
