I just had a friend give me his pc it is only 2 years old and in great condition. There is nothing wrong it. But I dnt have monitors and only have a 1080p TV. New to pc gaming and only know the basics. The card is a radeon hd 8570. It has a dvi out and hdmi out. But the hdmi does not work. Have used a dvi to hdmi adaptor with no success. Does this I have to buy a monitor with dvi ports on it. Or can I just replace the video card for a new one. My friend has mentioned he never used the hdmi only the dvi ports from card to monitor.
