I recently purchased a Macbook, and am currently trying to use it with my external display (Olevia 30" 720p HD-ready LCD, via DVI). My computer cannot find the manufacturer information for this display, and I guess as a result the Macbook has determined the external display is 4:3 aspect ratio. If I set it to mirror using a resolution with a 16:9 aspect ratio, the image is stretched on the external display, leaving black bands top and bottom. If the resolution is set to a 4:3 option, it stretches to fit the screen. Is there any software that can allow me to use this unrecognized display at the proper 16:9 resolution? Ive tried all of the obvious options messing around with settings already on the computer. Any help with this would be greatly appreciated.
