I just got Direct TV into the house and went ahead and got a second hd receiver for my upstairs computer that has a haup. 1600 tv tuner that is supposed to do HD. I see that my receiver only has an hdmi out and my card only has a coaxial in. That worked fine with cable that went through coaxial but how do I get a HD signal into my tv card? Am I going to have to buy a tv monitor? thanks for any help.
