Im looking to display some images at a church to some three 1080p tv's. I have a hp pavilion p7-1512 with a 1600x900 monitor. Im wondering what kind of setup can do this. More preferably maybe wireless like the chrome cast but just displaying a image or slideshow maybe. If that's not possible what other setups are available though like wires to one computer like a video splitter or something of that sorts. Help would be appreciated. This is the computerhttp://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c03632804 also does the computer need any hardware upgrades to to just that?
