DVI Cables

[NightShadeKW]

Okay, I have a projection HDTV and a CRT moniter, both with DVI ports. My video card has a DVI port as well, and I am hoping to have DVI cables to connect my video card to my HDTV and my video card to my moniter (obviously one at a time). I'm not sure about the differences between DVI-A DVI-A and DVI-D cables, but the ports on my video card and moniter look the same (the part to the side of the grid thing looks like a + with dots in each corner), but the port on my TV looks like just a -).

For my video card to my moniter, I happen to have a DVI cord that has the - like my HDTV, but it's too short to go to the HDTV and it doesn't seem to work with the moniter. Would a longer version of this cord work for my HDTV/Video card connection (I figure it'd have to be since it's the only kind that would fit in the HDTV port)? And do I have to get another cord with the + and the dots for my Video card to the moniter?

Another question, is the video card/HDTV connection even possible due to the differences in the ports?

Thanks for the help.

I dont know if that would work. DVI-A is an analog signal just using a DVI cable, it shouldnt work with regular DVI-I or DVI-D. DVI-I is the one without the dots. I remember when i tried to get DVI to work on my computer when i got a new LCD i had to install some new drivers and even then i had to play around with the Nvidia settings program before it worked. I know my vid card was DVI-D and the monitor was DVI-I, but ive heard that it doesnt work the other way. It might work with ur tv, but i have some doubts, I would try to make it work with ur monitor first, then if your vid card has a regular tv out, try that too, then try the DVI connection on the HDTV.

hope that helps

Which is which? the DVI-I is the one that looks like a minus, DVI-D is the one with the plus with dots? And what's DVI-A?

Also, If it wasn't clear, the HDTV and the CRT moniter are different ports. The CRT port and the Video card port are identical, I figure if I find a cord that fits exactly it should work, right?

As far as the TV, it's the one with the "-", so it'd be different than the video card I guess. I think the only one that would even fit between the two is the one like the TV, the other ones wouldn't even fit in the TV I believe.

Didn't read through the whole post, but this might help clear up some confusion.

Yeah, thanks, that helps. It looks like I need a DVI-I cable for my moniter to video card, and a DVI-D cable from the HDTV to my video card, if it's even possible.

Does anybody know if it's even possible to connect a HDTV with a DVI-D socket to a computer with a DVI-I socket?

I think a DVI-D cable should work fine. I think the analog part of the DVI output on the computer end is for use with DVI to VGA adapters and shouldn't be needed when using just the Digital signal. I've never done this though, so I'm not certain.

One more question - If I were to use an extension cable with a regular DVI cable for added distance (say, like 20 feet), would I lose video quality?

 

[NightShadeKW]

The reason I ask is that I had to get a really long audio wire a while ago, and I had to attach two cables together and the audio got a little fuzzy. Does anybody have any idea if a DVI cables with an extension DVI cable would lose quality?

 

[NightShadeKW]

I hate to keep bumping this, but I would really like to know if it loses quality over distance. I read that somewhere that it loses quality at 50 feet, but I'd only use maybe 20. Thoughts?

With digital audio cables, as long as you get a signal it should be fine. I'm not sure if this works for video though... only VGA experience here.

Heh, that was random.

Yeah, the center channel is especially large @ 46 pounds.

I don't think the floorstanders are unusually large though, just pretty heavy. (A lot heavier than my future housemate's Paradigm Phantoms anyway)

N64 and NES action is indeed sweet.
