Hello, I am trying to build an home theater computer, but I am having a problem with the HDMI. I need HDMI because I will be using a TV tuner card (in Japan) and they require HDCP.
The problem is that when I hook up my computer to my TV with HDMI the video is is limited to 1024x768. My tv is a 720p (1366x768) LG 32-lc2d . This tv has a restriction in the manual that says that VGA (D-sub) is limited to 1024x768. I can understand that, but why is HDMI also restricted? If I hook up an Xbox 360, PS3 or any other electronic video equipment by HDMI, I can get full screen with no problems at 720p or 1080i.
My computer is a Japanese Sotec(Onkyo) barebones. It is an unlisted OEM mother board, but it says ASUS on it. It is an NVIDIA 630i/ Geforce 7100 chipset with an HDMI port on the motherboard.
If I go into the Nvidia Control Center and change the resolution to TV: 720p, the image is overscaled( It doesn't all fit on the screen). 480p is the same also.
So the question is: Why does the 720p HDMI signal from my computer differ from the 720p output from say an Xbox 360 or such?
I am thinking of purchasing a new video card. Is there one that will put out a perfect HDMI signal? Is this chipset just too old? I can't output by component because I need HDCP for digital television. (True in Japan, but I don't know about the US)
So how can I fix this problem?
Thank you
