DVI output Primary, HDMI output Secondary?

I am trying to extend my desktop to my tv...which is across the room. So I opted for the use of the HDMI output on my EVGA GTX 460 so i wouldnt have to run an extra audio cable as well. I tried this and am getting nothing on my TV screen. In the control panel, the display isnt showing up. Just so I dont miss the obvious. Is it possible to have HDMI output as a secondary display while still having DVI port 1 for my monitor. If so. Any guesses on what I'm Missing?

also, I know the HDMI port works. Used it for my monitor for awhile just to test it out....switched back to DVI...better picture it seemed.

so i got it to show up finally....but it keeps cutting in and out like a bad cable. im having to run a 24 foot cable so doyou think the length is an issue?

or possibly the fact that teh stock mini hdmi to hdmi cable sucks?

thanks for the advice. I THOUGHT i was getting good cables. I work at best buy and get our Rocketfish brand really cheap. but they look and feel solid. also I'm having to use the "out-of-the-box" mini HDMI to regular HDMI cable from my GPU, then an HDMI coupler to connect to the larger rocketfish cable to make it to my tv (all this run under the house.) im guessing the coupler doesnt help anything.

so i spent most of the day looking at signal boosters and reading about them and when you need them. Thought I needed one but they say that they are rarely needed for HDMI runs less than 50 feet which im WAY below. Also, it says that a signal booster would be needed if the picture wasnt there at all or is pixelated which wasnt happening for me. So i continued with my troubleshooting. I am currently using a Rocketfish 4-way HDMI switcher because my tv only has 1 hdmi input. I bypassed this just to try and everything worked fine! which is awesome...but I still want to have an HDMI switcher. So I guess I need to front the extra money for a nicer switcher and try that. thanks for all the info though.

ok....so unfortuantely...the issue is not resolved. after too much time working...i got to use my "fixed" set-up again. Before. Since I had little time to test it, I called it fixed because the video no longer cut in and out like before. (So on that note the Rocketfish switcher still sucked.) the video remains constant and looks amazing, BUT the audio is cutting in and out now.

I spent a few hours looking through forums and EVGA and Nvidia help chats and noone seems to have the problem with the switcher....probably because most people don't need to use them, BUT i did find many people had the same issue when having the HDMI hooked up to run through a receiver, which is KINDa like a switcher in a sense.

Many people experienced the same audio cut out and noone yet has seemed to fix the problem who has MY GPU.

So again. Im open to ideas. it still baffles me that it works fine without the switcher or receiver. Something about the receiver and/or switcher messes things up.

I thought i needed a signal booster. tried that. same issue.

I would REALLY like to use my switcher if possible. It appears that nvidia has to do some Driver updates from what I read.

ANY NEW INFO WOULD BE GREATLY APPRECIATED!

thanks so far
