I am building a computer and started to watch the videos on newegg. They told me to do an external build first to make sure everything is in working order. I got to the part when I hook my video card up to my monitor and turn everything on. I used hdmi to my tv. I shorted the power to turn it on and nothing comes up on my tv. I am using a xfx radeon hd 6850 and an 1080p hdtv. Is this an issue with using a tv as a monitor right off the start or a problem with my motherboard/graphics card?
