Using the external display only

[Light49]

Hello i would like to use the external display only on this early 2007 macbook 13 , i tried this method but it didnt work im running lion 10.7.1

Can i get some help with this

To disable the internal screen for OS X Lion based laptops, launch the Terminal and enter the following command:

sudo nvram boot-args="iog=0x0"

You’ll need to reboot for changes to take effect, and the internal display will then be completely disabled regardless of whether the Mac is open or closed.

To undo this, you can go back to the Terminal and enter:

sudo nvram -d boot-args

Then reboot again, or you can just zap PRAM by holding down Command+Option+P+R during reboot, which clears out the boot-args as well. If you were to disconnect the MacBook Pro from an external video source, zapping the PRAM would be how you’d want to reenable the internal display.

You have two ways to setup it for external

1) Connect your/monitor or tv to macbook, and connect external usb keyboard, and close macbook bottom. It works well

2) move your menu bar in monitor settings to external monitor, and get off all brightness from laptop.

Sorry for bad english.

There is a third option you just remove the internal display: use this guide

And just don't put the display back.

But basically what mazahakato said is correct.

it's stupid to remove display cable from motherboard!
Because, if you have any situations, when you need it, and also, graphic card work ass well, and get of all brightness from macbook display, then he get off automatically. You don't need to remove this.

I know which is why i wrote at the end that what you said is correct as these are the normal ways of doing this. but his choice and honestly it doesn't harm the laptop in any known way.
