I'm fixing to get a budget rear-projection HDTV. I plan on having 3 devices hooked up to it and it has 2 component + 1 HDMI input. Aside from the usual attractions of typical HD programming, I am also looking forward to having a huge hi-res desktop from my computer. I would prefer to use the HDMI input with my video card to help text and whatnot remain legible just that extra little bit.
My video card has a DVI-I port, yet all the adapter cables I find are for DVI-D ports. From looking at the pin arrangements, the only difference I can see is the DVI-D port lacks the 4 rgb pins that would normally support the analog signal. It seems to me that wouldn't impede the DVI-D cable from being plugged into it and thus transmitting the digital signal. Does anyone have experience with hooking a computer up via DVI/HDMI? Would I have to get some sort of converter box? Will only newer DVI cards work or with just any as long as they support the requisite resolutions and scanrates?
Thanks,
Dane |

Most new HDTVs will only accept a DVI-D signal. My ATI video card had a DVI-I output and even though the DVI to HDMI cable fit, nothing appeared onscreen. I added an NVidia videocard with DVI-D output and it works great.
You can also get a DVI-I to component adapter. They support 1080i, 720p and 480p and run about $20.
To eliminate overscan, I run my videocard at 1200x666. It looks great, Text is easy to read and nothing gets cut off. I use Powerstrip to achieve this resolution. |

What nVidia card did you get? All the newer ATI cards specificially say they're HDMI compliant and advertise a TDMS processor. Is that what your card has? Is it AGP or PCI Express. All of those new ATI cards are PCIX only. I don't and won't have PCIX for a long time.
I really dont care about how fast the card is or anything, as long as it outputs a digital signal. I will fall bac on a 9600XT with that component adapter if all else fails, but I'd prefer the digital interface if I can.
Thanks,

My video card is a MX-440. It is AGP, and is an older card. I found it for about $50 6 months ago. |
