Ok, I have a Xenarc 700TSV in the front and thinking about adding 2 monitors in my headrests. 7" monitors are too big for my BMW headrests and I think I have to go 5.6" or 6.5" to get the job done. I am not going to add another video car, just split the VGA output to the two monitors. Since I am splitting, I am guessing that I will need go with widescreens to get the same resolution as the front monitor correct? Any idea of what i should do? It seems that most headrest monitors are not VGA and the resolution numbers are funky.
