DVI & HDMI are the same DIGITAL signal but HDMI incorporates sound along with video. As others have said, if you are running a 30' video cable, you want to go with a digital signal, not an analog one as with VGA. Finding a 30' VGA cable won't be easy or cheap (should be made with high quality low impedance cable), but a 30' HDMI cable (purchased locally) will probably take your breath away. For cables such as that, Ebay is your friend. You might also try <a href="http://monoprice.com">monoprice.com</a>. I haven't scouted them for HDMI, but have purchased hundreds of 3 wire fan extension cables from them. BTW, you do NOT need a Monster Cable or other such premium cable for HDMI. In fact, from what I have seen, the cheaper cables have performed as well as or better than the high dollar HDMI cables in head to head tests. Basically, the noise that is such a problem with an analog signal is ignored in digital signal and either the cable works or it doesn't. One further note, HDMI devices have a communication link that "tells" the source (video card, DVD player, etc.) what the display is capable of so you get something on the order of an auto-configuration. Finally, HDMI cables have a pretty weak connector that is easily broken if bent. I have noticed some HDMI cables that have a swivel on the end which should help prevent breakage. <br>

</div>I have a VIZIO 22" and tried with an existing VGA (8ft) cable that I had<br>
and the result was my top and bottom panels and open windows moved to<br>
the 2nd screen, the VIZIO while the desktop icons stayed on the 1st<br>
screen, my Viewsonic 22". The specific models are on my original post,<br>
"Using a HDTV for 2nd monitor" with links to mfg web pages related to<br>
the model specs. The VIZIO does not have DVI inputs only 2 HDMI (1 type<br>
1 and the other type 2), VGA, composite, S-Video and RF. I wasn't able<br>
to try the HDMI as my current setup the viewsonic uses the HDMI output<br>
from the MoBo and I can't use the HDMI at the same time leaving only the<br>
VGA output, that is why I was wondering if I should leave my Viewsonic<br>
alone and install my HD3650 PCIe x16 for the VIZIO, this way I could go<br>
with HDMI or as you mentioned DVI-HDMI for the VIZIO. I could probably<br>
try it tomorrow, I think the VIZIO did come with a short HDMI cable.<br>
<br>
I had also seen something about the limitations of Compiz-Fusion is<br>
restricted to a combined resolution that I had figured would be smaller<br>
than my 2 screens side by side, but was fine with one over the other.<br>
What effect would that have on my virtual display? Also what would<br>
happen if I were to set one over the other?<br>
