So, I tried to hook my macbook pro up to my Dell LCD display last night and had all kinds of problems. I used the adapter that came with my macbook pro. When I hooked it up the picture on the Dell looked horrible. I tied adjusting the settings which made it a little better but still not great. When I tried to mirror the monitor and clamshell the MBP the monitor was all choppy and almost unusable. Any ideas how to fix this problem? I had this Dell display hooked up to my old G4 tower and it looked and worked great.
