[QUOTE="bobtomay, post: 1498687, member: 24160"] There are no converters "from" VGA "to" displayport (or mini) that I am aware of. There are a few VGA "to" HDMI converters. The first problem there is that the accepted input resolutions are well below the resolution of that cinema display. The second problem is that most of them have a fixed output of 720p (1280x720), not only well below the accepted resolution of the monitor, but a 16:9 aspect ratio while the monitor is a 16:10 aspect ratio. And, I've heard that Cinema display will "only accept" a total of 3 resolutions - all of which are 16:10 ratios. The 3rd problem, there are no HDMI "to" displayport adapters that I am aware of. The Cinema Displays are probably the only displays on the market that only have a single input option. You may find a better VGA to HDMI converter - probably $200+ price range that could take care of the first and part of the 2nd problem. But don't know of anything to overcome the 3rd. Best solution to use that monitor may be to look for a modern switch that has all digital connections for video (with displayport output) rather than analog. Something like this - [URL="http://www.amazon.com/dp/B002S96MRQ/?tag=macforums0e4-20"]link[/URL] - and after reading the couple of reviews of this particular unit, I'd probably order direct from the manufacturer to make sure you get one that has the latest firmware already.
