Is there a setting I can change so that the video is always being seen? Or, should I just output audio via motherboard toslink, and send the video right to screen? If the latter, will I be losing anything? (I am running a 5.1 system for now)
I'm doing the same thing, and have the same problem. As far as I know, the problem is due to the fact that the BIOS screen resolution likely doesn't match HDMI specifications. It's not until Windows loads and pops over to 1920x1080 resolution (or whatever) that the HDMI port starts to work. I'm using a NVIDIA GT430, BTW.
You can use the Toslink if you want, but you won't get the HD multi-channel sound. You'll be limited to dolby digital/DTS or uncompressed 2-channel PCM.
In my setup, if I just use the HDMI connection, the video card freaks out when the AVR switches input or is turned off (it doesn't think the monitor is connected any longer) and this causes problems with my HTPC software (SageTV). This is an EDID problem you can read about in the HTPC forum. You may or may not see the same problem. Here's what I do:
I have an HDMI cable connecting my GT430 to the 1021K and another HDMI connected from the 1021k output to HDMI1 on my TV. This is the primary cable that all sound and video runs through.
I then have a second connection using a DVI---->HDMI cable connecting my video card to HDMI2 on the TV. I don't use this connection to view any video. However, I set my video card to clone the display over the DVI port. When the receiver switches inputs or turns off, it has the DVI connection to fall back to and my video card doesn't flip out. If necessary, I can switch to HDMI2 on the TV to access the BIOS.
