HDCP is not required or implemented for 480p in most cases.  So, if you are set at 480p (Lowest rez, PS3 video settings, not AUTO, or 720p), then it could be the adapter.  You need a Dual Link DVI to HDMI adapter, but even then, it's not guaranteed to work.

I had this problem with a DVD player with DVI out, it would not work above 480p with the DVI to HDMI adapter, HDCP was not working with the adapter.  Component was fine up to 1080i though.  I turned HDCP off (hack) for the player, but the TV still requires it, and it still did not work.  It was the ADAPTER, it is a Dual Link, but for some reason, it just did not work above 480p.

WELL what about a thing which can give you 1080p on a simple crt i use it its called a vga converter box and a dvi to hdmi converter works well on lcd,s giving 1080p i dont know why you are having a problem

u dont need a dual link dvi cable a single link will display 1080p and i can post the proof if it is needed

Single link DVI is able to transfer 1920 x 1080 resolution vs dual link at 2048 x 1536, but the dual-link uses additional wires, which distributes bitrate per wire, increasing the overall bandwidth.  However,  few devices that use dual link. Using a dual link cable for single link offers no advantage.   DVI does not carry AUDIO either.  IF single link works, then fine, but HDCP is still an issue.

u need a mac compatible video input must be hd if u want hi res but it will be difficult to do

@powerslave:

your r right sir but i just didnt have the money for a dual link cable so i got a single link but i might upgrade when i get the cash:P
