I have a new mid-2009 Macbook Pro hooked up to a 20" Samsung 2033sw LCD with a native 1600x900 resolution using a mini Displayport to DVI adapter that I bought off of EBay. No matter what I've tried I can't get anything to display on the external Samsung LCD higher than 1024x768. I tried switching between GPU's and that made no difference. Any ideas.?

It's an aftermarket adapter cable made in China. I have no idea if it works or not.

I pulled out an older LG LCD that is fairly generic, .e.g. it has DVI in at 1280x1024. Same problem on that LCD ... nothing (that is legible) higher than 1024x768, but this time at 1280x1024 I get major noise and screen distortion. The displayed image is jumping all over the place, but at least there is something displayed. Just to be thorough, I am going to try another DVI-D cable next.

Edit: I tried a different DVI-D signal cable, and now the display on the LG LCD is fine at 1280x1024. Next I'll swap the Samsung LCD back.

This is solved. It was the DVI-D cable. The original Samsung LCD now works fine at 1600x900. Thanks for the help.
