    Default GTS450 and HDMI Out

    Aloha,
    Sorry if this has been discussed before. Tried doing a search not only here in the forums but all over the net and have come up empty. I can't get my TV to work with my video card in windows 7.

    I have a Gigabyte video card (GTS450 series)

    1st monitor Samsung 24" DVI Connection
    2nd using the HDMI out to a SONY 40" LCD TV

    In windows XP it would display no problem on the TV. Until I did a cleam install using Windows 7 Ultimate 32bit. TV won't be dectected in properties (Display) nor in the NVIDIA control panel.

    Also if I have the HDMI cable plugged in the computer and reboot. The dvi (Samsung) monitor will show the windows display but won't get any further. So I can't log into windows and have to unplug the HDMI cable and reboot.

    other notes: I have not tried DVI to HDMI cable yet. I would have to order that as my computer to tv is about 30 feet away.

    Any help is appreciated.

    Mahalo

    Have you tried the latest GFX drivers, and or old ones?

    If not I'd give that a shot, and also be sure you have the latest chipset drivers installed

    Odd to hear you have issues in win 7 but not XP, makes me think it's a driver issue more than a cabling issue.

    Thanks for you response

    update:
    1) Tried another HDMI cable problem still exists
    2) updated nvidia graphics drivers no change


    My Gigabyte motherboard might not fully be supported for HD. IF anyone knows?
    Model# GA-EP45-D-S3R/DS3

    The board definately has support for HD Sound. But like stated previously it might be a chipset issue. Will look into this when I get home

    Thanks again. Any other help please chime in

    I have found a few interesting things using the HDMI output first not related to you question. I will get to that.

    I have to identical screens Samsung 2494hs I connected one using the DVI and the other using the HDMI and they are totaly different pictures. both color wise and size wise. Dont know how that works.

    Any way back to your question make sure you give the HDMI plug a good push and wiggle into the socket I have to do this every time I use it. I hooked up a HDMI TV that was in another room as a multiple display. It was nearly impossible as the drivers kept defaulting it to the main screen and the screen near the PC was blank. I had to bring the TV in the room with the PC where both displays were so I could set up the drives so the the PC screen was the master and the TV would just be a copy of the PC screen and not an extended screen or anything else.

    Good luck the latest drivers also helped me. now I can just plug the tv in and it remembers the last set up.

    Good news almost there....

    I guess the MINI HDMI Slot is really a tight fit and close to the back wall part of the computer case. For some reason I pushed in the MINI HDMI Adapter and pluggged in the HDMI Cable to the video card and PRESTO.... I get video on my SONY TV screen.

    Have to do some adjustments on the television as it seems a little dim compared to the monitor.

    Other notes....NO SOUND going to the TV....lol

    Any suggestions or am I asking for too much and should be counting my blessings? haha

    Unless you have connected the spdif output on your mother board to the video cards input you wont have any sound through the HDMI port.

    Two options are available connect the mother board connector to the video card input. or use the back panel sound output from your mother board to connect to the audio in of your tv or amp.

    this is no longer true for 400 series cards. The GTS450 GTX460, 465, 470, 480, 570 and 580 all use onboard HDMI audio components which are independant of any soundcard you may have installed in your system. It does however require the correct driver installed to work. This should be included in the Forceware driver package. The latest audio driver version is 1.1.9.0. Look in device manager under Sound, Video and game controllers for entries (usually around 8 of them) all Marked nVidia High Definition Audio. If they are missing then you don't have the correct audio driver installed.

    Interesting I have just upgraded from the gigabyte 260 to the Gigabyte 460 and you are correct I can not see the audio connectors on the board. I have been using the latest Nvida drivers but never had sound out of the HDMI card. I normally go into the MB sound drivers and change from the speaker output which I have connected to headphones for use in front of the computer or change to the optical output which is really the co axial output for connection to my surround sound amp when watching movies on the TV.
