    i had bought a PCI- HDMI cable recently
    to see a movies from my computer into my tv
    and i have 2 problems.
    1) i have awful noise when i turning on my tv. the only way i could handle the problem is to put on the TV mute.
    can it be a problem on the TV or on the cable?
    2)when i use XP windows i can see both (tv screen and computer screen)
    but when i'm using windows 7 i can see just 1 screen. it is just the tv. if i'm trying to use both, my computer screen turning off and i see just the tv screen,and to see the computer screen over again i would have to disconnect the HDMI cable.
    what should i do to see the windows at the both screens?
    maybe can i use some software to makes things easier?

    regards roman
