Hi, I recently got my retina macbook pro with the LG display, not problems so far. One problem I have noticed is connecting my external display (dell) to it. I cant go over the 1024x768 resolution and it just looks horrible! I have tried the "detect displays" trick with no new resolutions appearing. On my older 2009 macbook pro it looked good and the res went way higher than that. What can I do? Thanks!
