I have looked for hours upon hours of all the forums. So here goes... I have a Black Macbook running Snow Leaopard with a mini DVI to VGA adapter. I have the VGA running to the back of my Samsung LCD 37" HDTV. But when i press the source button on the tv, it says "no input device are connected". I have tried multiple things such as picking a couple random displays (800x600 etc.) I have also tried mirroring displays. The crazy thing is that when i cascade my desktop or show my spaces, it shows the external monitor next to my main screen. I read somewhere that if you get the refresh rate below 60hz that it would work, but thats not an option. My mouse even acts like it goes to the next screen when i drag it all the way to the right. I have called Samsung to no avail, even AppleCare couldnt really help. If you solve this, you should put your application into AppleCare Support. This is urgent that i get this fixed by Sunday Morning, Thanks for your help!!!
