Hi, I am new to this forum. I have couple of questions. I connected my Dell dimension 8250 PC (XP Prof) to Samsung Plasma TV via DVI to HDMI. I can not make out any difference between VGA to VGA connection and DVI to HDMI connection in the picture quality. Do I need to adjust any settings to make it better? My second problem is that there is no audio coming out of this DVI to HDMI connection. I thought when connected via HDMI it carries both video and audio. Is there something I am missing or this is how it is. Appreciate any response.
