I am the IT guy for a company and I had another employee ask me to give him some min specs for a new pc he was getting for his office. Long story short, he bought 2 19" Coby Tv's as displays rather than regular monitors like I would have liked. I bought a dvi to hdmi cable off amazon and hooked it up but the second display wont come up under windows 7. It's a brand new hp6510f with a Radeon HD 4200 onboard card in it. Any help would be appreciated.
