Got a 3D LG Plasma. Got 3D game - Crysis 2. Got a PS3. What I haven't got is the 3D working. Crysis says I need HDMI 1.4. Is this as simple as getting a 1.4 HDMI cable or is my big, fat old style PS3 out of date too?
Your PS3 will be fine. You need a particular standard of cable because the older ones aren't capable of the data speeds needed for 3D. Old Category 1 (aka "Standard") cables can transmit data at upto 2.25Gbps, newer Category 2 (aka "High Speed") can transmit up to 10.2Gbps.
