my laptop has the following ports- USB iLink S-Video (tv out) express card slot pc card slot RGB Monitor modem port network port can I use any of these to make my laptop the screen for my playstation 3? which i think uses hdmi? Do i need to buy anything?
That will only accept a normal composite or s-video signal at crappy normal PAL resolution of 576(625) lines - not what you want out of a fairly sophisticated device like a PS3 which can give HD images!!. The lag will be horrendous and the pictures unwatchable.
Trust me, it ain't worth it - buy a cheap LCD tele from Ebuyer or ASDA or somewhere - you will get much much better results.
