I recently purchased a 22" widescreen LCD monitor from Dell. It has 1 DVI input on the back. My video card has 2 DVI outputs. Currently, I am using the DVI cable that was supplied with the monitor and recently read about HDMI. If I purchase 2 DVI to HDMI adapters and run an HDMI cable between them, is this better or will I notice a difference compared to using a straight DVI cable?

If it even lets you do this (the DVI to HDMI converters may work in only one direction) the image will not be any better, it may even be a little worse going through the converters. What the HDMI converters are designed for is flatscreen TVs that have HDMI input. Very few flatscreen TVs actually have a DVI input, so it is a way of sending a digital signal from your computer to an HDMI equipped flatscreen TV.

Thanks for the info, I suppose that makes sense that it could actually make the picture worse. But, let's suppose I have a 37" LCD TV that has an HDMI port on it. I get the adapter to convert the DVI port on my PC to HDMI and plug that into the TV. I've learned that an HDMI cable supplies both sound and video. How would this work in this situation? Would it know just to supply the video and thats it? I would be running this through a stereo receiver that has HDMI ports on it. I'm assuming that I would have to use the optical or digital sound output on my video card to connect it to my receiver. But, if HDMI supplies both sound and video, would this create a conflict? How would it know which to use for sound?

In my last post, I meant sound card, not video card. I would use the optical/digital port on my sound card.

I read somewhere (I do not remember where, it might have been on a package I have for a DVI to HDMI cable, at home) that with a DVI to HDMI cable/adapter only video is sent. That makes sense in that the DVI standard is strictly a "video" standard, audio is not part of the specification. So yes, you would have to send the audio across a different cable(s).
