Protocol?

The article claims: "Protocol: 3 × transition minimized differential signaling data and clock" - Wouldn't "6x transition minimized differential signaling and clock" be more correct, as single-link DVI (with 3x TMDS) is only a subset of DVI? 87.189.122.81 (talk) 20:34, 13 April 2014 (UTC)[reply]

Request: could someone add a connector compatibility table?

Could someone who understands this stuff construct a connector compatibility table in the main article?

I found this Wikipedia article when trying to determine whether or not I could connect my Dell G2210 LCD monitor, via a Sandstrom AV S10HDV11X HDMI to DVI Adaptor, to my Android tablet (which has a mini-HDMI socket). The photos in this article are very helpful and allowed me to answer my question with some additional reasearch which I share below.

The Dell monitor is listed as having DVI-D interface with a native resolution of 1680 x 1050 at 60 Hz (it includes HDCP capability). Neither the Sandstrom specification nor the Dell specification go as far as identifying the link capability (single or dual link). Fortunately this can be inferred from physical inspection of the connectors (prior to a purchase being made in the case of the converter, scrutiny of the Sandstrom website product photograph): the Dell G2210 supports DVI-D single link and the Sandstrom converter DVI-D dual link. (The Dell monitor has a dual link DVI female socket and the cable from my PC a single link DVI male plug.)

The $64 million question: are DVI-D dual link connectors pin compatible and functionally compatible with DVI-D single link connectors?

And the answer is: yes to both questions.

My current PC configuration confirms pin compatibility.

With regard to functional compatibility, the single link DVI specification supports a date rate of up to 165 MHz (1680 X 1050 resolution with a 60 Hz data rate requires a 146 MHz link pixel clock speed); a higher resoloution than this requires a second link (hence the 'dual link' reference). I got this answer from the Play Tool website (courtesy of a Duck Duck Go web search): http://www.playtool.com/pages/dvicompat/dvi.html

Video game consoles with DVI?

Although DVI is predominantly associated with computers, it is sometimes used in [...] video game consoles... Does any video game console natively output in DVI? The PS3, Xbox 360 (Post-Elite models), and all eighth-generation consoles can output HDMI, and the Dreamcast, PS2, and Xbox 360 have had first-party VGA cables; but none that I know of can output DVI without use of third-party adapters.
