I recently bought a Mac mini but I still haven't been able to connect my monitor. The Mini-DVI to DVI adapater doesn't work with my PC DVI adapter (all to do with the variations in DVI-I and DVI-D etc). So I need to buy another adapter. I noticed there's a MiniDisplay to VGA as well as a Mini-DVI to VGA adapter. Is there any reason, other than price, to chose one over the other. I'm connecting to a fairly old TFT monitor with 1280 x 1024 resolution.
