You do not need another card. HDMI video is the electrically the same as DVI with out the audio signal. You should be able use a DVI to HDMI cable or adapter to drive a TV. I have not done it this way but I have done the reverse with my Sharp Blu-ray player HDMI output into my Sony (1920 by 1200 resolution) DVI input monitor. Google (dvi plus audio to hdmi).
Sorry I should have mentioned that I have a dual monitor setup. Both of the DVI outputs will be used for my computer monitors. I will not have an extra DVI to connect to a TV.
I am just guessing but I think your suggestion will not work for what I want. I think it would display my desktop on the TV. I want to 'preview' the video on the TV.
If the Decklink wont work i doubt anything will.
this is a common issue with cheap motherboards especially MATX.
if the Dell bios was more open you could probably get it to work.
you could try adding a 2nd video card but this creates other issues and rarely works right.
this is the only option you have if you cant buy a new system.
Add another cheap graphics card and set up in your "Playback settings" the other monitor. Here is a picture of my Timeline on monitor 1 and Playback of HDV on monitor 2. My computer desk does not have room my playback monitor horizontally only vertically I assume this is the type of thing you are trying to accomplish
You can also try Matrox option :
MX02 Mini desktop is a PCIe card with a real breakout box, with a very good rendering engine with HDMI,components and composite output.
It's around 400 $ without the MAX option. For Dell compatibility, you must go to Matrox forum (MXO2 mini pre-purchase section)
Hope this helps
We are also using Intensity Pro and recently purchased an Osprey 700e HD. Here is how you hook them up to your computer and some demos:
