I just installed Parallels 8 on my Retina Macbook. I have a 30-inch Dell monitor connected via a Dual-DVI Link. The resolution on the large monitor seems stuck at a 1024 x 768 resolution. I tried changing the monitor settings in Windows and while the change appears to start out correctly (the login screen is at the new resolution), as soon as it logs on the resolution switches back to 1024 x 768. If I drag the VM window to the Retina Macbook display it seems to work much better. Parallels makes the proper adjustment on the Retina display to upscale the objects on the screen to appropriate resolutions. But it does not seem to handle external monitors correctly. Any suggestions would be appreciated.
