Does your vizio provide edid information? When you press the Guide 
button on the remote what does the vizio list as the resolution?

I had a similar problem with my vizio but it wasn't providing edid info 
for the vga input and I had set a modeline in X whcih seemd to work OK 
but wasn't right. The resulting display was squashed horizontally and I 
had to stretch the display to make it look right. Ultimately I was able 
to tweak the modeling to get it to use the native resolution. My vzio is 
720p resolution so my experience may not be applicable to your situation.
