I'm trying to use my Samsung flat-screen (not plasma, just good ole flat-screen) as an external monitor. I bought the much-maligned Dynex mini-dvi and am running a VGA cable from the dynex to my tv. Like everyone else, I'm getting sweeping images in black-and-white and it looks like my tv is stuck between stations. I get close to a decent (still black and white) image at 600x480 @ 60hz, and I've read that 50hz will solve it, but 50hz isn't an option on my Macbook.

Does anyone have any suggestions?
