Im just wondering whether i can connect my ps3 to my laptop and use it like an ordinary monitor. Before you say anything I have a Dell Inspiron 9400 and I have DVI and VGA input. Im pretty sure I have a HDMI port too but i dont know if thats for input or output. I have tried connecting the ps3 to the DVI port using a HDMI-to-DVI cable. I dont know how to make my laptop act like a normal monitor. I have a max resolution of 1920x1200 on my laptop and an Nvidia GeForce 7900 GS Go graphics card. Is there some other software i need? Is what im trying to do even possible?

Other PC specs (I dont thing theyre nescessary but here anyway):

Windows XP Pro SP2
2GB RAM
1.83GHz Intel Core 2 Duo
50GB free HD space
