View Full Version : Will Apple ever adopt HDMI for their displays?

I'm wondering if Apple has been looking at HDMI (http://www.hdmi.org/consumer/faq.asp) as a means of connecting their displays to Macs, especially the 30" and any bigger displays Apple makes in the future. Not only is HDMI backward-compatible with DVI (and DVI forward-compatible with HDMI!), it has enough bandwidth to drive a 30" display without needing two links. Plus, HDMI cables (http://www.hdmi.info/) are quite a bit smaller than DVI cables (http://www.laaudiofile.com/tadvi30.html).

HDMI and DVI have completely different plug designs.

HDMI is a digital video interface just like DVI. It is infact compatible in the sense that you can get an adpater plug that allows a purely digital DVI to HDMI or vice versa conversion. I believe other than the actual pin configuration of the two interfaces the video portions are identical. HDMI also has extra pins for audio. I believe the OP is trying to suggest such a change, because HDMI is becoming a standard for home theater applications and apple could market the 30" display as a HDTV monitor because several cable boxes, newer DVRs, and most new HDTVs are moving to this interface. In my mind, this may be unecessary because cinema displays don't have audio support. And you could simply use a HDMI to DVI adapter to hook up a HDMI cable box, etc to the cinema display. Also, DVI single and dual link connections have the exact same pin configuration, dual link just uses all 24 pins and single link uses just 12 of those pins.

However, its resolution is too low to be used as a replacement for my 23" Cinema Display. OTOH, the number of pixels available on a 30" Cinema Display is massive overkill for watching or even editing HD video. However, it is physically too small to really enjoy the HDTV experience. I come on the side of those who believe that there is no point in targeting the 30" display as HDTV/computer monitor.

I agree with you - that's why I suggested in my original post that if Apple were to use HDMI, it would be purely as a DVI replacement. What I didn't say is that it probably won't happen until even dual-link DVI becomes insufficient.

Even though I do like smaller cables, the DRM is a showstopper for me- http://slashdot.org/article.pl?sid=05/01/17/1825232&tid=196 :o

I read through the article on Slashdot and many of the comments - it looks like HDMI is a complete non-starter, at least for right now. All I want out of a DVI replacement is something that offers the same, or better, quality that DVI has with more bandwidth, a smaller cable, and is easily adapted for older DVI connections - basically HDMI without the frills.
