7300GT - how to disable VGA output?

[mcjam]

Hi,

 

OS X 10.6.4 detects a second display on the VGA output of my 7300GT even though there is no display attached.

Is it possible to disable the VGA output by editing the EFI string?

 

Thanks in advance!

I used the following .plist to generate my current EFI string:

 

				<key>@0,compatible</key>
			<string>NVDA,NVMac</string>
			<key>@0,device_type</key>
			<string>display</string>
			<key>@0,name</key>
			<string>NVDA,Display-A</string>
			<key>@1,compatible</key>
			<string>NVDA,NVMac</string>
			<key>@1,device_type</key>
			<string>display</string>
			<key>@1,name</key>
			<string>NVDA,Display-B</string>
			<key>NVCAP</key>
			<data>
			BAAAAAAAAwAMAAAAAAAABwAAAAA=

			<key>NVPM</key>
			<data>
			AQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA==

			<key>VRAM,totalsize</key>
			<data>
			AAAAEA==
			</data>
			<key>device_type</key>
			<string>NVDA,Parent</string>
			<key>model</key>
			<string>Nvidia GeForce 7300 GT</string>
