I bought an ACHIEVA Shimian QH270-IPSI 27" and it arrived fast. I hooked it up to a mid-2011 27" iMac using a mini-display port to dvi-d adapter. It is in dual screen mode. The iMac detects the monitor and its 2560x1440 resolution and let's you drag windows over to it, but the problem is nothing shows up on the QH270 monitor. The monitor is slightly lit (not totally dark black) but totally blank. In my imac control panel in the display section when you select "Gather Windows" it shows a window for DVI monitor but doesn't have any resolutions listed.
What do I need to do to get this monitor working on this iMac? Even if it's complicated, please tell me. Thanks.
