A properly shielded VGA cable will provide excellent video quality at high resolutions.
Yep: BNC > VGA. There's a
reason that it comes standard on the back of good CRTs.
I, of course, prefer displayport.
Thunderbolt is some good tech. If it were pushed by everyone else besides Apple it would currently be a lot cheaper and ubiquitous right now.
but it will always be expensive. No matter how ubiquitous it gets.
VGA should be dead by now. I have no clue why it still appears on anything.
VGA is very useful as a sort of legacy connection you can use. With HDMI and DP being common, and DVI still appearing somewhat, you may or may not have the proper connection, so it's worth it for a lot of people to just use the legacy VGA port that they know will work. It might not be full resolution, but sometimes it just has to work.
Of course dual-mode displayport solves this. I really enjoy it and would like to see it on more devices. After a significant amount of looking, it turns out you can't actually get it on a computer that's under like $700.
