DVI-D is all-digital. DVI-A had a similar formfactor, but used 4 pins above & below the horizontal bar on one side to carry the analog signal. DVI-I has the pins for DVI-D, and also has the pins for DVI-A.
As far as I can tell, there's no official mapping for DVI-A pins to a HDMI connector, even as alternate signals (which would seem to be the most sensible way for it to be implemented... kind of like how most new cell phones can temporarily repurpose the USB clock and data lines and use them to carry analog stereo audio to a pair of headphones, avoiding the need for a new jack (I think the iPhone goes a step further, and sticks a LED within view of the USB port's interior cavity, so you can even connect SPDIF via the same physical micro-USB connector using a special Apple cable, but I could be wrong about that one).
For what it's worth, I bought the cable pictured in my post above, but it doesn't work, and I'm trying to figure out at this point whether it's a configuration issue with the laptop and/or my TV, or whether it's a fundamentally lost cause that physically can't work. I deleted the HD-DVD player from NetCommand, and replaced it with a "PC" connected to the same physical port, but when I select it I just get a black screen that says "PC" if I hit the info button on the remote.
Thought: does the TV support just about any reasonable vertical and horizontal resolution that a normal multisync monitor could handle (even if it did it badly), or does it LITERALLY support ONLY timings that would be valid for TV use (1080p60, 720p60, 480p60, etc)? If it ONLY works with a few SPECIFIC timings, and you feed it an invalid signal, will it at least tell you it sees an invalid signal? Or will it just stupidly sit there in silence, giving you no clue that it IS actually seeing a signal, but it's invalid (I've learned the hard way that this TV's designers don't seem to have been very fond of useful error messages... or error messages at all, for that matter).
Alternatively, does anybody happen to know whether the Intel 945GSE is one of the chipsets capable of outputting YPrPb to the RGB pins on the VGA connector, and if it does, whether it's a capability that needs extra hardware and explicit support from the manufacturer to work, or whether it's something that can be forcibly enabled, even if the OEM doesn't support it, by using the OEM driver instead of the "official" one, then adding/changing a registry key or using a program like Powerstrip? I know SOME new computers & laptops have the ability, so you can skip the active RGB->YPrPb converter and get away with using a cheap cable like the one below... but I can't find any info one way or another about the MSI Wind itself (it's not for HTPC use... it's to let me extend the desktop onto the TV when I'm using my laptop in the living room).
