ASUS A7000-X/T/32 Radeon 7000 32MB 64-bit DDR AGP 2X/4X Video Card

I just bought a ASUS A7000-X/T/32 Radeon 7000 32MB 64-bit DDR AGP 2X/4X Video Card offline. I bought this because i have a extra computer in the house and figured I would put it in the bedroom to watch AVI's. So i needed a video out. The problem is i can't seem to get it to stay just video out. Everytime i restart my computer if won't go back to the video out. I am really tired of dragging my monitor in the bedroom. Does anyone know anything about this video card or the setting to make it stay video out and with no monitor. Thanks!
