    I'd like to know if it's possible to transmit things like Youtube video, or whatever is showing on my computer screen, to my big HD TV in the other room. So many devices these days, I'm sure something like this exists? My TV doesn't have any wireless ethernet or anything like that. My new motherboard has an HDMI output on it, but then I'd have to get a 25 ft or so HDMI cable to go from the computer to the TV..

    Search for "wireless HDMI transmitter". You will need a receiver to match for the TV.

    A good 25 foot HDMI cable would be cheaper and more reliable. http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10240&cs_id=1024001&p_id=...seq=1&format=2

    With the HDMI cable connected from my motherboard, directly to the TV, if I'm watching for example, a Youtube video and click the full screen button, will it display properly on the TV?

    That usually works, if you set things up correctly, but you will see the whole window, including borders, if there are any.

    Configure the video card to use the native resolution and refresh rate for the TV. You will have to experiment to see if cloning the PC desktop or extending the PC desktop works better. If the desktop is extended, the window that contains the video will need to be dragged to the desktop area assigned to the TV. PC audio should be set to use HDMI. Note that some video cards (onboard video in particular) only allow one digital output to be used at a time. If that is the case, the PC monitor needs to use VGA.

    The TV should be set up to use "just scan" or whichever setting configures it for pixel-to-pixel mapping, so there is no overscan compensation. If that isn't enough or isn't available, there are usually a few picture adjustments available on the PC side to correct the problem.

    Hmm seems confusing already. If it helps, these are my mobo and video card:

    Motherboard:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16813131730

    Videocard:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814161315

    And my TV is an older 720p HDTV with HDMI inputs

    The thing I don't get is that the mobo and the video card both have HDMI ports. Which would I use to to connect to the TV?

    And another thing, what's up with HDMI with ethernet? How is that possible? What does one have to do with the other.?

    Yet another thing, I see that blu ray players come with wifi built in. What is the point of that? If you have a blu ray player, then aren't you going to play discs on it? Why does it need wifi?

    I don't know what settings your TV has to permit pixel-for-pixel mapping. You will need to consult the manual for that information.

    If you have a discrete video card installed, you need to use the conections on the video card. Based on what I saw at AMD's website, it looks like your video card lets you connect any two of its three connections that you want to use.

    AMD Vision Engine Control Center (the successor to Catalyt Control Center) has HDTV mode support for 720p60 (fine for most 720p TVs), but if your TV's resolution isn't a perfect 1280 x 720, the "HDTV Support (Digital Flat-Panel)" section permits you to set a custom resolution.

    HDMI audio would be configured using Control Panel->Sound->Manage Audio Devices

    100 Mb/s Ethernet capability was added to HDMI with version 1.4. so the devices connected by the HDMI cable can share an Internet connection. I don't know if this new ability is currently used by any devices.

    Blu-Ray players have wifi because some can connect to the Internet and stream content from Hulu, Netflix, Youtube and other sources supported by their firmware.

  7. I connect my computer to my TV with a 30' HDMI cable & my computer talks to my TV sort of & says what resolution to use & no borders. What you see on your computer screen you see on your TV.....I have a 720p plasma.

    Ok here's a good example, I want to watch the pres debate tonight on TV, I don't get Bloomberg channel on my cable, but it's going to be on their website: http://www.bloomberg.com/tv/ If I buy the HDMI cable, would I be able to click the full screen button on the computer and watch it on my TV?

    At 25ft you need a good quality HDMI cable.

    Best to set it up first with a short cable. Then if you can't make the long cable work, you will know it is the cable. Return it for a better one.

    You will save money buying online (e.g. Monoprice) but that won't get you a cable tonight.

    Buying tip: Long cables work best with thicker gauge wires (e.g. 24 or 26 AWG gauge) but the cable itself gets thick and stiff. 28 AWG cable are more flexible but also more subject to problems at long length. 26 AWG is a good compromise.

    The tech guy at that site said I'll probably need an extender/booster because of the distance, but told me to contact my video card manufacturer to ask what the max distance is before I need the booster..

    Ok, cable arrived in the mail today! I hooked it up to the graphics card and my TV, set the TV to the HDMI 1 input port. But cannot figure out what I need to do in Windows, or whatever other settings to output to the HDMI port on the card.. Any suggestions to take me the rest of the way?

    Nope, this is a 35 ft cable, bought it from Monoprice. I halfway figured it out, in the display settings in Win 7. The resolution is kinda funky though..

    Try a short cable first to separte encoding vs cable issues.

    The cable is working fine. I'm just trying to figure out how to have 1680x1050 on my computer monitor and 1280x720 on my TV Right now I can only pick one resolution for both screens.

    Video looks fine, the AUDIO is screwy! See screencast I made showing weird things happening with audio:

    http://screencast-o-matic.com/watch/cX62VxT7a

    A youtube video is playing and there is audio for the duration, but for some reason the audio plays for a second or so, then cuts off for several seconds, then back on for a second...

    In my experience with clone mode: ATI drivers limit you to the same resolution on both displays. Nvidia drivers let you run different resolutions on each display -- the smaller res display is a scrollable window onto the larger displays desktop. That probably wouldn't work for you -- you'd be missing a lot of the picture on the TV. The best setup is to have 1920x1080 displays on both the monitor and HDTV.

    To set different resolutions for the TV and monitor using an ATI video card, you need to set up the TV and monitor in an extended desktop. You must then drag the window over to the part of the desktop assigned to the TV to watch it on the TV.

    I downloaded this ATI Radeon Catalyst Control Center software which is ridiculously confusing to use. If I use the extended desktop option, how does that create the different resolutons? And if it's extended, what happens if you click a full screen button for video, does it fill up both screens as that would not be good...

  24. Two monitors as one desktop (ie a single app can be enlarged to fill both screens) requires both be the same size. Two monitors as two desktops allow different sizes on each screen (an app can only fill one screen).

    Extended desktops can be different resolutions. I tried an experiment where I had Monitor 1 set at 1920x1080 and Monitor 2 set at 1280x1024. If you drag a window all the way over to the TV side of the desktop and enlarge to full screen, it should only fill the TV. At least that was my experience.
