I have a iMac 2.4 GHz Intel Core 2 Duo and a Bush TV that also hase a PC option on it i have used a DVI or Mini DVI cable cant remember to a VGA port that then goes into the back of my TV. But i cant get the right resolution for the TV. The TV says it is 1600x1200 but it gives me a 4:3 size screen and is really pixilated. How can i solve the issue please help. And if there isn't a way do you know of any cheap external monitors that work well with mac & are around 23" Any help will be truly appreciated.
