My 2010 MBP is connected to an external 27"1080p external monitor via mini display port to HDMI (with adapter). The screen size fits in the monitor, but the resolution is very low (definitely not HD and definitely much lower than the standard resolution on the MBP). I've messed with various settings and am not sure what the problem may be. Any help? Okay, correction. Here's my connector set up: mini display to DVI (adapter) > DVI to HDMI cable.
