Hi Guys, Thanks for even just looking at this thread! I bought a Gateway FPD2275W 22' external display about a year ago to work with my Xbox 360. Since then I have been trying to hook up my macbook (intel core 2 duo) to it with bad results. I have OS X 10.5.5 installed and am unable to run the Display at its native 1680*1050 at 60Hz resolution. The highest resolution I can get it to run at is 1360*768 at 60Hz. It wont display anything when I set the resolution to 1680*1050. The monitor doesnt go into sleep (which im guessing means it is receiving a signal). I am using a mini DVI to DVI converter attached to my macbook and the DVI input goes directly into the monitor. HELP! Thanks again!
