Have this adapter to operate the sole purpose 3 identical monitors with a HD5870 Vapor X. This is ideal. No problems in the 2D / 3D mode. Connected: 2x DVI and 1x DisplayPort to VGA Super product. Does what it should and is not qualitatively inferior, what you can expect from HP yes.
(What could be more important: to date Best Displayport> VGA, then both can follow DVI runs during the PC. First, then let PC with the highest / biggest resolution that follow with the smaller resolutions The VGA monitor in the middle set)
