[SOLVED] Raspberry pi works on every TV but my 42" Vizio (device_name=VIZ-VS420LF1A)

[akevit]

FINALLY FIXED

I had to set hdmi_group=1 then had to specify hdmi_mode=31 (1080p @ 50 hz)

Modes 4 and 5 also worked (720p and 1080i respectively), though have not tested playback with these. So far playback in 1080p @ 50hz is working fine though.

Edit: I should add that it was defaulting to mode 6 which was 1080p @ 60hz, for whatever reason this wouldn't work.
