What is "FixEDID"?

With "FixEDID" you are able to apply EDID patches, display model overrides and add scaled resolutions.

How to use "FixEDID"

Using FixEDID is very simple!

1. Start "FixEDID".

2. Select display if needed.

3. Open the EDID binary file with the "Open EDID Binary File" button.

4. Select the display panel override

5. Optionally disable the IODisplayPrefs check so that it checks on which

    display adapter the monitor is connected

6. Optionally add / fix the monitor ranges (if your EDID doesn't have them or they are bad)

7. Optionally add scaled resolutions by entering the resolution and clicking add.

    For adding them to the list click the "Add Resolution" button.

    You can remove entered resolutions by the "Remove Resolution" button after selecting it.

8. Click the "Make" button and it generates the overrides on the desktop!

NOTE: You need to install either the display override in /System/Library/Displays/Overrides or install DisplayMergeNub.kext in /System/Library/Extensions. It will also generate an EDID binary for checking afterwards...

You can also enter parameters manually...

The app also has quick select buttons for displays (open display menu press 1 - 9, these are listed).

The app also determines aspect ratio based on the first detailed descriptor block in the EDID when you open the EDID.
