My Mac Pro 1.1 has two DVI ports which seem to be the only ones that I can use for display. I'm using one port with a VGA adaptor to a Viewsonic monitor. Will the other DVI port on the Mac support a 1080p output through an HDMI adapter to the Sony video monitor? If so, is there a DVI to HDMI adapter available for this Mac and will it support 1080p?


Thanks for your help. I'm working with Snow Leopard 10.6.8.

Will the other DVI port on the Mac support a 1080p output through an HDMI adapter to the Sony video monitor? If so, is there a DVI to HDMI adapter available for this Mac and will it support 1080p?


Yes. For example this one,


DVI-D Single Link Male to HDMI® Female adapter


Update:

The above is the physical connection. I am not 100% sure your card can handle the hdmi though.

Feb 21, 2012 2:58 PM in response to Barbara Smits

I hate to appear stupid about DVI connectors, but my female end has four squares with a cross in the middle on the right side, not a single link?????? I don't think mine is a DVI-D????


It most certainly must be DVD-D (or-I) and if the monitor resolution is greater than 1920 x 1200 it is a dual link DVI.


I miss interpreted your post where I though the monitor had a HDMI connection. If it is DVI, and your card is DVI, you should be able to plug it into the card without an adapter. Again if the resolution is greater than 1920 x 1200 the card DVI would need to support dual link.


FWIW, you could add a 5770 card to your model.

Feb 21, 2012 3:04 PM in response to Barbara Smits

FYI, I did a little searching and the DVI ports on that card are dual link.


At any rate if the monitor really has an hdmi connection then the adapter I linked to earlier is the proper one. I am still not 100% sure whether the card can supply the full HDMI video signal though (I specifically said "video signal" since DVI does not pass audio).

Feb 21, 2012 3:10 PM in response to Barbara Smits

No, and if you look at the product page comments? I gave you link and recommended with good reason; 'tons' of users of 2006. As is the Barefeats results. And all the threads here. Apple is always saying only supported and not tested in earlier models. And there is a tech note.

The X1900 only worked in 2006-7 and your processors tell us that you have 2006. That is the card that clogs and pulls in dust and is a huge problem with heat, having to be removed 3x a year to unclog, and requires boost of the 3 system fans by an added 300 rpm.


Early 2008 was different animal with 800MHz FBDIMMs, PCIe 2.0, 64-bit EFI firmware finally (64-bit mode).

Feb 21, 2012 3:20 PM in response to Barbara Smits

A bunch of google searching did not turn up any definitive info on whether the apple card can support full hdmi. However I did find the specs for the standard x1900 card,

ATI Radeon™ X1900 Specifications


And there's a line that says "DVI 1.0 compliant / HDMI interoperable and HDCP ready". So it probably does handle HDMI properly. But then there's a footnote on that item which potentially adds a whole new wrinkle -- HDCP. If the card really isn't HDCP complient (it's "HDCP ready", whatever that means) and the monitor is I am not sure it will allow the video even if the card can pass the HDMI.
