I purchased MBP to use it, among other things, for VJing. A lot of great VJ software is available for both OS X and Windows platform and i use it both. I purchased DVI to S-video adapter and connected MBP with projector and it worked perfectly well.. Then I switched to Windows and tried to get the same thing but I couldn't get anything on projector. I guessed that it could be something wrong with adapter so I tried to connect regular monitor directly to MBP DVI out and it didn't work as well... Got back to OS X and it worked perfectly. Under windows, when i plug DVI adapter to DVI out, it recognize "something" and it allows me to add secondary display in graphic card settings but doesn't output anything. I tried to replace original ATI drivers with Omega alternative but that doesn't make any difference... Anybody had similar problems? Is this driver/compatibility problem or it's just my MBP? Any solutions? Thanx!
