Hey,
im trying to set up a triple monitor display with my XFX HD-577A-ZNFC Radeon HD 5770 but my main monitor, a cheap LG 26' screen, is not reading anything through the VGA port. I pluged it into my PS3 component to see if it works, and it did. I also tried other computers in the VGA and nothing.... different cables and all.

Why would just the VGA port not be working and is there a way for me to fix this?

Thank you,
Nick
