Ok, so I'm ordering my Mini in a few weeks once my tax refund shows up. I'm wondering if there are any advantages between Mini DVI to VGA or Mini Displayport to VGA adaptors. Also I already have a mini dvi to VGA adaptor.
I'm also thinking about running dual displays. One with the mini dvi to VGA adaptor and the other with the mini display port to VGA.
Also, what are the advantages to running a dual display set-up?
One basic technical difference between DVI (and mini-DVI) and the DisplayPort is that the DVI interface provides both digital and analogue video signals whereas the DisplayPort is a digital video interface only.
I assume you know that VGA is an analogue interface.
To provide a Mini-DVI to VGA adapter only requires straight remapping of the individual connecting points of each standard, for a DisplayPort to VGA adapter electronics are required within the adapter to convert the digital only signals of the DisplayPort to the analogue signals required by VGA.
That increases the cost of the adapter and theoretically at least could also degrade the video signal somewhat due to the extra conversion.
Ok, so then I'll use the adaptor I already have then. But, is there any advantage to using a two display setup? I'd have two 17" CRT monitors hooked up. I'm not too sure what I would use them both for, but for some reason this sort of seems appealing. Any thoughts?
There are a number of different VGA to analog video converters available but many don't work very well. So read up on reviews before you buy a specific one or make sure you can return it if it's not suitable.
But that concept (MDP > VGA adapter, then VGA > analogue video converter) seems to be the only reasonably priced solution.
