Video: EDID Management - With Generic EDID

Steps

Sometimes there is no display to copy an EDID from — or copying one would be the wrong thing to do. An LED wall is the usual case: the processor wants a specific, non-standard pixel count that matches the physical panel layout, and no off-the-shelf monitor advertises it.

The generator builds an EDID from nothing but the numbers you give it. Where a display is connected and its timing is what you want, the sibling procedure — building the EDID by importing from the connected display — is the better starting point.

Before you start

• Know the exact pixel dimensions the wall or processor expects. This whole procedure is only as good as that number.

• Know what the controller supports — bit depth in particular. Asking for 10-bit from hardware that cannot take it buys nothing.

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

1. Open the EDID generator

In the Hub, select the server and click System Management.

Under Configure → GPU → EDID, find the EDID editor panel and click Create generic (generator).

2. Enter the resolution and timing

Under Resolution & timing, set Width, Height and Refresh (Hz) to what the wall actually needs. The video builds 7800 × 1060 at 60 Hz — an ordinary LED-wall figure and exactly the kind of number no monitor would ever offer.

Connector and Timing are already set sensibly: DisplayPort with CVT-RB v2, which is the reduced-blanking scheme for wide modes. Leave them unless the link is genuinely DVI or HDMI.

3. Set the colour depth

Under Color, set Bit depth to what the processor and panels support — 10 in the video, because that chain handles it. Format stays RGB for a normal LED processor feed.

4. Leave the rest alone

Below that sit Include secondary VICs, the extra Color spaces (BT.2020, DCI-P3, AdobeRGB), DSC and Audio. They exist so an EDID can be shaped in detail when something downstream demands it.

For a straightforward LED wall, none of them need touching.

5. Name it and generate

Under Name, fill in Monitor name — this is the name the GPU will report for the output, so make it recognisable. Then click Generate EDID.

6. Save it to a slot

The generator answers with a green EDID ready box reporting the size — 256 bytes for a single-block EDID. Give it a Slot name and click Save to slot.

The slot name is separate from the monitor name and is not capped at 13, so this is where a fully descriptive label belongs — the video uses LED7800x1060, which says the resolution outright.

7. Assign it to the outputs and apply

The saved EDID now appears in the Assign EDID dropdown of every output under EDID override per output. Choose it for one output and press Apply, or set it on several and use Apply all.

A confirmation names the cost before it starts: roughly 20 seconds per output — about 80 seconds for four.

Done when

Every output you assigned shows the generated EDID as its Current source, marked as forced, and the saved EDID is listed under Saved EDID slots where it can be re-used on any other output — or downloaded as a .bin and imported on another server.

Clear override on a row, or Clear all override, returns the outputs to the displays' own EDIDs.
