Yes you can. I used to have the VooDoo 3 3000, excellent card. Unfortunately I have forgot the procedure, but this will bring your request back to the top of the page, and someone will be able to advise.
From what I can remember, you will need to right click on your desktop, choose properties from the drop-down menu, then click on the settings tab, then advanced button, this will take you to another window, click on the adaptor tab, this will show your card and it's settings. From there you will be able to set your display to the TV.
That's about all I can remember, but someone else will hopefully pick up on this and fill in the missing bits. j.
