I have a newer thunderbolt display and an older Apple Cinema HD display hooked up to my retina macbook pro (15 inch, early 2013, 1 GB GeForce GT 650M graphics card). The older one is going through a mini-displayport interface to a dvi cable hooked up to a thunderbolt port, while the newer one is on thunderbolt.

However, I've only been able to get as high as 1280 by 800 resolution out of the older monitor. Is there a way to get it to display at a better resolution?

Open sys pref- display

Hold the Option key before clicking the Scaled radio button

Now you will see all resolution profiles that are supported for the display.

Something like I have for my Sharp TV

display resolution

  • Is there a difference with holding the option button? It only shows 1280x800 and 1024x640.

The monitor used dual-link DVI. I was able to get it working using this adapter, and it now displays up to 2560 x 1600:
