I have a mid 2009 15" MBP that I've connected to a Dell U2311H via the Apple Mini Displayport to DVI adapter in clamshell mode. Although it should be a digital to digital connection text looks smudgy and rough. It almost looks like VGA output. Would getting this Mini Displayport to Displayport cable provide better quality video output? The Dell U2311H has Displayport input. I hope so because the current Mini Displayport to DVI output is very disappointing. I know there is a difference in display resolution between the MBP and U2311H but I get better video quality running 10.6 on a Windows machine in VMWare Workstation on a display with even less resolution. Thanks.
