    Translating resolution from Win to Linux


    OK, it's a little bit more complicated than most cases. I have a monitor that is actually a TV (it's a Syntax LT27HV 27" LCD TV). It has a VGA input, which I currently use under windows and have it set to 1280x720, 32bit color and 60Hz refresh rate. So my problem is that there isn't enough info on the TV to set horizontal and vertical refresh rates in the xorg.conf file. So I went searching for it, and found that a lot of people us PowerStrip in Win to adjust the TV using these settings:
    1280x720p=1280,48,160,200,720,24,10,48,81000,2052
    or:
    Horizontal
    Active:1280
    Front Porch: 48
    Sync Width: 160
    Back Porch: 200

    Vertical
    Active: 720
    Front Porch: 24
    Sync Width: 10
    Back Porch: 48

    I also know that the TV can supports 24-bit natively, so this shouldn't be a problem. So far, I've only been able to run X at 16-bit, at 24-bit I get no signal to the TV, I figured this is due to the refresh rate problem.

    Bumping this back up! There's gotta be a way of doing it...

    I currently have it set up at 1024x768, which means I can only use 4:3 view instead of full screen (or else the screen looks really stretched. I put the 1280x720 mode in there but the xserver still starts with a 1024x768 (which I'm guess is because it's having problems with the 1280x720). Currently this is what my xorg.conf looks like:
    Code:
    # nvidia-xconfig: X configuration file generated by nvidia-xconfig
    # nvidia-xconfig:  version 1.0  (buildmeister@builder3)  Wed Dec 14 16:39:22 PST 2005
    
    # xorg.conf (Xorg X Window System server configuration file)
    #
    # This file was generated by dexconf, the Debian X Configuration tool, using
    # values from the debconf database.
    #
    # Edit this file with caution, and see the xorg.conf manual page.
    # (Type "man xorg.conf" at the shell prompt.)
    #
    # This file is automatically updated on xserver-xorg package upgrades *only*
    # if it has not been modified since the last upgrade of the xserver-xorg
    # package.
    #
    # If you have edited this file but would like it to be automatically updated
    # again, run the following commands as root:
    #
    #   cp /etc/X11/xorg.conf /etc/X11/xorg.conf.custom
    #   md5sum /etc/X11/xorg.conf >/var/lib/xfree86/xorg.conf.md5sum
    #   dpkg-reconfigure xserver-xorg

    I would just like to say, I have succeeded! I was able to find this site (if someone else in the future needs help):
    http://www.linuxis.us/linux/media/ho...iguration.html

    Which pretty much was what pushed me to success. Turns out I had to do set the Modeline option in my monitor section.
