HDMI output stop working. please help

my graphic card is Asus ENGT430. it has HDMI, DVI , and VGA output.

on my old computer, dell inspiron 531, I have 2 monitors ( one using dvi, another using VGA), HDMI connects to my 60'' LCD TV. If I open up NVIDIA control panel, all three monitors are listed there. I can pick which two I want to use (this graphic card only supports 2 monitors).

Now I got a new rig. its sandy bridge 2500k. I did the same thing, using same graphic card. but I only see 2 monitors in the NVIDIA control panel. 60'' LCD tv cannot be detected. I have latest driver installed. what else should I check?

  1. I had problem like that with one of my computers connected to LCD TV, it would not detect it unless i have turned on TV switch it to HDMI mode, and then powered on computer, but im guessing you already tried that
  2. ye, already did that. I guess I just use my xbox 360 to stream videos.
