So i just bought this tv this weekend (Insignia™ 55" Class / 1080p / 120Hz / LED-LCD HDTV Model: NS-55E560A11) but i'm having problems with it lagging a bit behind the controls on my PS3. I put in Guitar Hero to see and it was about 150 ms off. i tryed a HDMI and Component cables and both are the same and also when i tryed to watch a Blu Ray the pictured would speed up at times along with the the sound being slightly off. I have my display on my ps3 set at 1080 p and have the others checked, is there any other settings i need to change to fix this?
