    Unhappy 1080p / nvidia / DVI-HDMI - NO WORKIE RIGHT!

    Soft-n-Hard: JVC 47" 1080p LCD : NVIDA 6800GT AGP : mythbuntu 7.10 : restricted drivers

    Problem: Incorrect detection of resolution ( twelvesomthing X 720 )
    want full 1080p resolution.

    I know: Dual boot to Windows XP works fine (the screen resolution!)

    I've tinkered with xorg.conf all I care to.

    Anybody got 1080p working ???? Tips ????

    Sincerely,

    Take a look and see if it will help you too.
    (There are some xorg.conf there that you can look at).

    Hey,

    I got 1920x1080 working from setting Nvidia to Auto and it goes for the top resolution my display can handle.

    Another site worth checking is the Knoppmyth forums and wiki - many of the posts there work with Myhtbuntu.

    Also, I think there is setting about NoEID (or something similar) setting in xorg that tells X11 to ignore what the display says it can show and just display it.

    Cheers,
    Steve

    The problem solved itself.

    The JVC 47" LCD, was at certain times rebooting, over and over again.

    I took the JVC LCD back and traded "up?" for an LG.

    Mythbuntu booted right up into 1080p thru the DVI/HDMI.

    Apparently, if your going to use an HDMI port for a PC, look close to the specifications, it may ease your pain.

    Now onto other issues.

    Thanks for the tips.

    I had several issues trying to get several 42" lcd tv working. I finally took my computer to Best Buy and tested several HDTV's. I found that the LG brand was the best as far as automatic resolution, picture quality and price.
    Thanks

    It took adding my refresh rates manually and the
    Code:
     Option       "ModeValidation" "NoDFPNativeResolutionCheck"
        SubSection "Display"
            Modes        "1920x1080_60"
    otherwise I was getting shoved into 1280x700 .. I bought the vizio I did specifically because the specs gave 1920x1080 as a valid resolution.

    I hope this helps ..

    Re: 1080p / nvidia / DVI-HDMI - NO WORKIE RIGHT!

    I haven't got my flat panel showing any more than 1024x768 yet and I think the clue might be in the "NoDFPNativeResolutionCheck" option.

    I don't have a great understanding of xorg.conf (yet) but I was surprised that all your modelines are commented out. I didn't know it would work without at least one modeline.
