    I am hooking up my PC to my 47" LCD TV with a DVI to HDMI cable. While watching normal digital calbe I can see these fainst horizontal line scrolling vertically on my screen. If I unplug the HDMI PC cable the lines go away. Would a better cable fix this or is there another solution or reason for these? Thanks

    A different cable would be a good place to start since it's the cheapest fix. Give it a go! :toast:

    You may have a broken wire in the cable you have

    When I am using the PC on the TV it is fine but the DVI/HDMI cord seems to cause interference when I am watching cable on the TV.

    I hope you're not serious. Overpriced "high-end" HDMI cables are nothing but a gimmick. Get a regular HDMI cable.

    +1 to what erocker said monster cables are the same as your normal cable just have a shiny coating to make it look pretty

    Go to your local cable provider and tell them the HDMI cable they supplied you with isn't working right. I did this and got a high quality cable for free!
    erocker says thanks.

    Ahhh! My cable box is hooked up to my TV using Component Video. My PC is hooked up to my TV using a DVI to HDMI cable. While watching cable TV i get the faint horizontal 'floating" lines that seemed to be caused by my PC being hooked up to my TV. If I unhook my PC they go away. Is this a problem with the HDMI/DVI cable, PC, perhaps I shouldn't use component video from the cable box?

    I had this same problem when I first started using an hdmi cord. I got a new cord but the problem persisted. The problem is probably not with the hdmi cord but with the graphics settings. Here is the solution. If your using windows 8 (and it is probably similar with windows 7), right click on the desktop. Go to "graphic options" then "output to" then "clone display". Finally, select "digital television + built in display" By making this change the horizontal line went away.
