As you maybe know, some displays, especially laptops displays, are not recognized by System Preferences or System Profiler.

Result is "unknown display" message.

If you're perfectionnist, and have some time to spend, here how to solve this question.

 

You need to inform about Display's VendorID and DeviceID.

- Go to System Preferences -> Displays -> Color,

- check "show profiles for this display only",

- Then Open Profile.

- Scroll to "tag" "mmod",

- You will see 'Manufacturer' and 'Model' fields.

 

Now, create a folder named DisplayVendorID-XXXX

where XXXX should be your Manufacturer infos, All firsts 0 need to be skipped.

 

i.e: my manufacturer is: 0000320C

So the folder should be named DisplayVendorID-320c

 

 

Then, onto this folder, create a file named DisplayProductID-XXXX

where XXXX should be your Model infos, All firsts 0 need to be skipped.

 

i.e my model is: 0000027D

So the file should be named DisplayProductID-27d

note: if the model is 00000000, DisplayProductID-0 should works.

 

This file is a plist, but without .plist extension.

Copy and paste this code inside your DisplayProductID-XXXX:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>DisplayProductName</key>
<string>Your display name here</string>
</dict>
</plist>

 

Save the file, without any extensions (even not .plist or .txt)

 

Now copy folder to System/library/Displays/Overrides.

Done.

 

- If your Display is already recognized, but you wish to modify the name, scroll the Overrides folder until you find the folder matching your manufacturer, then create a new file inside following 'DisplayProductID' instructions above and add plist entries to override name.

 

-I f you don't understand any step above, download SwitchresX and modify display informations.
