Thread: vga and dvi usage

this may be the wrong place for this question, so mad please move as necessary.

the question.

i have on my computer a vga output and a dvi output,now not knowing anything about dvi i persume its a better video output. but as i have both on my comp. can i use them for dual monitor.

by either buying a

1.dvi ts screen and a vga screen
2.vga ts screen and a dvi screen
3.convert dvi to vga adaptor then a vga to rca cable
4.vga to rca cable on vga and use a dvi ts screen

the idea is i have 2 standard rca screens and i want to put 1 in the back of the car and the ts in front.

thanks
