Do i need to keep the box if i have a problem with the lcd to send it back or can i use any box? When I run dual screens on my lcd and big screen through s-video on the big screen the big screen turns to crap, it won't stop scrolling black streaks. is it possible to run the big screen as a second monitor or should I just leave it alone with my 2005. I tried messing with the settings on my x600 (it sucks but i am getting a gtx512 soon) but nothing changed with the big screen, and I am afraid to set it as a primary because I might not be able to set it back because I won't be able to see anything. Anyone know?
