c'mon Monkeychees, you should know this by now... although 90% of LCD's have DVI input, they don't all support HDCP.
Before you all rush out and buy this cable, check your monitor manufacturer's website, or the manual, and see if your monitor supports HDCP. If it doesn't you can't connect your PS3 to it, although a 360 will work.
I can confirm a ViewSonic VA1912W doesn't work with a PS3, nor does the LG L172WT.
