hdmi doesn't have enough bandwidth to transmit 1080 picture @120Hz, while dual-link dvi does.

according to wiki
HDMI version 1.0–1.2a 1.3 1.4
Date initially released December 29, 2002 June 22, 2006 May 28, 2009
Maximum clock rate (MHz) 165 340 340[53]
Maximum TMDS throughput per channel (Gbit/s) including 8b/10b overhead 1.65 3.40 3.40
Maximum total TMDS throughput (Gbit/s) including 8b/10b overhead 4.95 10.2 10.2
Maximum throughput (Gbit/s) with 8b/10b overhead removed 3.96 8.16 8.16
Maximum audio throughput (Mbit/s) 36.86 36.86 36.86
Maximum color depth (bit/px.) 24 48[A] 48
Maximum resolution over single link at 24-bit/px 1920×1200p60 2560×1600p75 4096×2160p24
Maximum resolution over single link at 30-bit/px[C] N/A 2560×1600p60 4096×2160p24
Maximum resolution over single link at 36-bit/px[D] N/A 1920×1200p75 4096×2160p24
Maximum resolution over single link at 48-bit/px[E] N/A 1920×1200p60 1920×1200p60

they have the same throughput.

1.4 supports 3d stuff with "the frame packing 3D format at either 720p50 and 1080p24 or 720p60 and 1080p24, side-by-side horizontal at either 1080i50 or 1080i60, and top-and-bottom at either 720p50 and 1080p24 or 720p60 and 1080p24.[123]" but no 120 hz

Hmm, interesting. And here I always thought HDMI was the superior cable. Would I be able to watch blu-ray with a Dual-link DVI? I thought there was some DRM issue and you had to use HDMI. How would I watch 3D blu-ray movies if I can't use HDMI?

Best solution

afaik you dont need to have 120Hz to watch 3d bluray, so hdmi 1.4a will work just fine.
and hdcp works over dvi on most 'newer' monitors as well
