Could you please list the rest of your PCs specs and relevant driver versions (most importantly the OS and whether its 32 or 64-bit, the AMD driver number and the iz3D / DDD driver numbers). If you run the DDD AMD checker
, do you pass? Are you running Crossfire or anything weird? Are you running dual monitors? Sometimes you might have to have the TV as your sole output (primary display with no secondary monitor). Did you try switching which HDMI port it was plugged into on the back of the TV (sometimes only 1 works for 3D). Though I have neither an AMD card nor a 3D HDTV, so I can't really help you further.
