Is is possible to have a second monitor connected to my dell 620? the only port is VGA. I've tired VGA to VGA, I found via internet a VGA to (split)S-Video/RCA (female) cable. I've tried connecting them single and together directly to a second monitor. I also tried using an RF Modulator trying every connection i could think of along with "Display Setting" with no luck. I KNOW SOMEONE HAS THE ANSWER!
