I'm planning to give a talk at a conference, and I've been told that slides will be displayed on a screen with a resolution of "2048 x 1080 (16:9 aspect ratio)".
I want to see how my slides look at that resolution. I have a Macbook Pro (non-retina screen) running OSX Mavericks and no external display.
In System Preferences, I can choose between only two "scaled" resolutions: 1280 x 800 and 1024 x 640.
Is there a way that I can use an unlisted resolution?

To see all graphics supported modes use the alt key before clicking on Scaled in display preferences.
To see it in 19:9 use a Thunderbolt cable to a TV. (assuming you have those)
If you have a Mac like I do (MBA 2012) then using the Thunderbolt you can get up to 2560 by 1600 pixels on your HDTV.
