How can I connect my ps3 to a Samsung SyncMaster 931bw and what do I use for sound?

Answer 1

You need a HDMI 1.3 to DVI-D cable. The PS3 has a smaller than typical HDMI connector (hence the 1.3) so make sure that you get a cable wiht a connector that will fit.

Your monitor supports HDCP encryption, so there is no problem when you put in a Blu-Ray disk and the encryption gets enabled.

For audio you need to connect separate speakers to the regular audio outputs of the PS3.
