I have a MacBook Pro, bought 3 years ago, I'm not sure of the model, but the processor is a 2.66 GHz Intel Core 2 Duo, with 4 GB of RAM, nVidia 9400M 256M. I am using MacOS 10.6.6.

Next week I will do a presentation in a conference, and they suggest to use a 1280 x 720 resolution, as the conference will be recorded using the 16:9 format.

Unfortunately, when I want to change the resolution of my screen on my laptop (System preferences > Displays > Screen resolutions), it does not provide this resolution. I can use 1024 x 768 which is the "backup" resolution for the conference, but not the suggested resolution.

So my question: is there a way to force such resolution on my MBP?

If you connect it to a display that offers 1280 x 720 as a resolution, then it should give you that as an option. You need to test it with the display that you will be using at the conference, which is always a good idea.

Ok, so if I understand well, even if my MBP can't display (or at least does not provide) 1280x720 on the laptop screen, it will be able to output such resolution? – romaintaz Apr 13 '12 at 9:11
Correct. As Mike says when you connect to another display or projector the computer will offer different resolutions for you to choose from when that display is chosen. – Richard Apr 13 '12 at 10:47

edit /Library/Preferences/SystemConfiguration/ add these lines, save & reboot.

<key>Graphics Mode</key>

to edit you may have to copy it to your desktop first, edit it and then put it back to where it was, overwriting the original file
