HDMI not recognized on Asus mobo
I've built a PC using an Asus P5G41T-M mobo w/ an HDMI connector. I'm currently using an nVidia GT220 hooked to a Dell monitor at 1920x1080 (VGA). I can't seem to get the PC to recognize the HDMI port. The manual is pretty slim and only mentions that an HDMI port exists. On the Asus web site (after filling out lots of extraneous info) I was able to register and check out their 'support' forum. Not much help there. There was a small article about the HDMI working only if there was nothing plugged into the (onboard) VGA or DVI. I'm not using any onboard video, I'm using the nVidia. Is there some setting in Win7 that I need to check? I generally use Linux, but this is a PC I will be using for video editing (converting old VHS tapes to DVD).
