I've been running a Benq G2400W on my MacBook Pro since December 2008 with no problems. I recently has my logic board replaced due to a power issue. I got the computer back a few weeks ago. For some odd reason, my monitor refuses to accept the signal from my MacBook Pro over DVI. I can use the DVI to Analog converter and it works just fine. I did find a thread over at Apple Support Discussions outlining the exact issue I am having. The solution is to remove a pin from the DVI cable. I shouldn't have to destroy a cable to get this to work again. I might order a new cable/adapter from monoprice.com and destroy it if that is my only option though. I just can't figure out what changed except for the logic board swap...but I don't remember if it has worked over DVI since I got it back. I deleted the windowserver plist for my user and the system one with no change in behavior. Are there any other settings I could try resetting? I've unplugged the Benq and reset the monitor via the OSD to default settings. I did read over at anandtech that it could be HDCP related...but I'm not trying to watch a video. I plugged the laptop into a Dell 1905 at work via DVI and it worked perfectly fine. I'm completely baffled. Thoughts?
