    Hello, I'm trying to set up an hdtv for a friend right now. I dont really know much about it, and I'm having some problems.

    I'm fairly certain that I have the right cords in their places. I have an hdmi cable coming from the tv to the cable box. I also have some red/green/blue cables connected as well, though I hear they are not needed if you have an hdmi cable. The problem comes from not seeing any hd channels. Everything just looks junky and low res. I have changed the input settings to hdmi 2 which is where I have it connected. He is using Comcast cable with an hd box so I'm assuming he has access to hd cable.

    Do I have to change some settings within the menu systems of the tv and cable box? Do I have to call the cable company to activate them. I'm really confused, I have turned off both the tv and the cable box and turned them back on but it still looks horrible. Will the hd channels automatically work on their designated channels or do you have to go to a different channel. Like fox is on channel 6 but hdfox would be on a different channel?

    Sorry this post is a little convuluted, I'm finding it hard to put things into words. If anyone has any ideas of what I can do, they would be appreciated.

    First Name:
    check the tv setting - 576 - 1080 P
    most broadcasts in UK if in HD are 1080i

    also check the cable box for those settings
    is the user subscribed to receive HD ?

    Don't assume. Comcast charges extra for HD. If your friend isn't paying for it, he's not getting it.
