So, I have the 2.0 Aluminum MacBook and I have an old 15" HP LCD Monitor. I connected it to my MacBook using the Mini DisplayPort to VGA adapter and it works great. No problems at all. But...when I tried to connect my MacBook to my 42" Samsung Plasma TV (has a VGA port), my TV screen reads, "Check Signal Cable." I don't understand. I've connected a Toshiba and an HP laptop to this TV in the past with no problem. Why won't my MacBook connect with it? Anyone know what to do about it?
