Default Screen Resolution Choices

Hi,

I'm running Mavericks (10.9) and I have a bvu165lt connected to a Dell U2412M monitor. This monitor is capable of 1920x1200 but I'm only able to run it at a maximum of 1920x1080 - the OS gives me no other choices. Is there a driver or OS problem here, or am I doing something wrong?

Thanks.

I forgot to mention the computer in question is a 2013 Macbook Air.

On Diamond's website I read that this product should support resolutions up to 2048x1152.
However the product name is "BVU165LT" which seems to imply that it is using our DL-165 chip. The maximum resolution for this product is 1920x1080 and this would explain your findings.

You would need a DL-195 based device or better to drive 1920x1200.

We'll contact Diamond to raise their attention on this inconsistency. You may want to do the same.

Thank you for your reply. I suspected as much, as I found the original packaging which does not agree with the maximum resolution information posted in the product site. Since I have only one external monitor at 1920x1200, it is a simple fix to switch to a cheap passive mini displayport to displayport cable. I'll reconsider a DisplayLink option should I ever add a second external monitor.
