BrishenThank you, I wasn't aware of the limitations with an active DP->DVI adapter, I thought those were limited to the passives, but it appears as though I was wrong. Removed the incorrect post.
SeanCA dual-link DVI to HDMI converter will be active (if they ever make one). Due to the architecture differences, you need to multiplex the 2 DVI links into a single one at twice the frequency, so that requires a powered chip. There's a whole ton of fun issues with transcoding video, bringing DP into just becomes frustrating.
