An active adapter? I am supposed to buy and use (instead of a simple cable) a device that actually eats power and reprocesses the signal? I assume that the resulting image quality can't be great, particularly at high resolutions (1920x1200). Might even be worse than with VGA connection.
Which probably means I'd better stay away from monitors with only DisplayPort inputs as long as I use Linux.
Not quite, the Dell adapter has a good link up from the looks of it, and the Apple has some issues with non-apple monitors (lol, figures). It would be risky indeed, and maybe saving up for a 5xxx series would be better
