I am looking for the best video card to use 3, 32" led tv's in an office environment where the same information is displayed on 2 tv/monitors and then the 3rd tv/monitor will only be seen by me for costumer privacy. 2 of the displays will be for me and my customers working environment and will have the same information displayed while the 3rd is for my in process research that that my customer cannot see. I would like to use hdmi or dvi.
