DVI to HDMI on geforce4 ti 4600
So I recently got a new HDTV (a Panasonic PT-47X54). I am currently using an s-video cable to run the tv off of my visiontek geforce4 ti 4600. I was looking to upgrade my picture quality. The TV does not have DVI input but has component and HDMI inputs. After reading a lot about DVI to component transcoders, I was wondering if I could just use a simple DVI-D to HDMI cable to achieve my goals. It seems that this is my cheapest option, I was just wondering if it would work and if it would be of high quality. Also, will i still need to play around with PowerStrip to get everything to work? Thanks for your advice.

Monster Cable has a dvi to hdmi cable, but it is expensive...

I'm having a similar problem, except I want to connect my GF4 Ti 4200 DVI output to my Panasonic PT-AE700 projector's HDMI input.
Before bying an expensive cable, I have tried to check if this should work. And as far as I can see, it seems as if your DVI must support HDCP (a copy protection), to be able to connect to a HDMI device. Futhermore, it seems as if the GeForce4 series doesn't support HDCP. At least I've read a document (http://www.dvhardware.net/article2470.html) that claims that some of the news in NV40 (GeForce6 series) was support for HDTV and HDCP:

"The Inq reports that NVIDIA's NV40 will have some additional video capabilities. It looks like that all the NV4x cards will feature these options.

As for HDTV, Nvidia claims Transport stream handling, HDTV output (720p, 1080p, 480p CGMS) and HDCP - High-bandwidth Digital Content Protection as well as HDMI High-Definition Multimedia Interface support."

But I don't know how reliable this source is, so I'm still looking for some evidence that it should work!

I have now got some clarity in this issue, and this is how DVI/HDMI and HDCP works:

If the source is HDCP coded, the receiver (in my case the projector) must support HDCP. If the source is DVI/HDMI without HDCP, it doesn't matter. You can connect it to any receiver that can handle DVI/HDMI. (xmasgrin)

I have a Panasonic PT-AE700 connected to a DVI PC card. I use Power Strip to set the correct resolution, but the image do not fit well. Someone known the correct setting of the time parameter?
