    EDID Modelines Direct From Your TV/Monitor.

    If you are having a mountain trouble with the published (usually incorrect) modelines, then get correct lines directly from your TV/Monitor.

    Your TV/Monitor stores this data in PROM (programmable read-only memory) or EEPROM (electrically erasable PROM).

    EDID stands for "Extended Display Identification Data".

    You can get the modelines from your TV/Monitor's EDID information by running the command:

    startx -- -logverbose 6

    from the console. The EDID information should then be in /var/log/Xorg.0.log (or /var/log/XFree86.0.log). This works for the proprietary NVIDIA driver. I am not sure if other drivers display as much information.

    Using any -logverbose level greater than or equal to 6 will give all the EDID info you need.

    In particular, it checks all the EDID modelines and inbuilt X-server modelines (which includes various standard VESA modelines) to see if they are valid. If a modeline is found to be invalid, it states the reason why.

    On my amd64 box with a Philips 170S I get something like this:

    EDID from a Philips 170S LCD Monitor

    Code:
     --- EDID for Philips 170S (CRT-0) ---

     --- End of EDID for Philips 170S (CRT-0) ---
    And in the "Validating Mode" section:

    Code:
     Validating Mode "1280x1024":
       1280 x 1024 @ 60 Hz
       Mode Source: EDID
         Pixel Clock      : 108.00 MHz
         HRes, HSyncStart : 1280, 1328
         HSyncEnd, HTotal : 1440, 1688
         VRes, VSyncStart : 1024, 1025
         VSyncEnd, VTotal : 1028, 1066
         H/V Polarity     : +/+
       Mode is valid.
     
     Validating Mode "1280x960":
       1280 x 960 @ 60 Hz
       Mode Source: EDID
         Pixel Clock      : 108.00 MHz
         HRes, HSyncStart : 1280, 1376
         HSyncEnd, HTotal : 1488, 1800
         VRes, VSyncStart :  960,  961
         VSyncEnd, VTotal :  964, 1000
         H/V Polarity     : +/+
       Mode is valid.
     
     Validating Mode "1152x864":
       1152 x 864 @ 70 Hz
       Mode Source: EDID
         Pixel Clock      : 96.76 MHz
         HRes, HSyncStart : 1152, 1224
         HSyncEnd, HTotal : 1344, 1536
         VRes, VSyncStart :  864,  865
         VSyncEnd, VTotal :  868,  900
         H/V Polarity     : -/+
       Mode is valid.
    
       AND MANY MANY MORE.

    What I propose, is that everbody collects the EDID
    information from their TV/Monitors and publishes it here.

    So Jade still has a thread running.

    Not bad for someone who was buried some time ago.

    Just noticed that the horizontal frequency of the above modeline is out of range. So, try this one with a lower HSync:

    ModeLine "1600x1200" 202.50 1600 1664 1856 2160 1200 1201 1204 1250 +HSync +VSync
    # 1600x1200 @ 70 Hz (VESA X-Server) HSync: 87.5 kHz

    Hope this works.

    Yeah, I copied the wrong specs.

    The Compaq P700 crt monitor has the following modes:

    1600x1200 75Hz
    1280x1024 60Hz 85Hz
    1152x864 75Hz
    1024x768 85Hz 110Hz
    832x624 75Hz
    800x600 85Hz 120Hz
    640x480 60Hz 85Hz 120Hz

    Clock speed 189 MHz
    Horizontal frequency 30-92 kHz
    Vertical frequency 50-120 Hz

    http://www.monitorworld.com/Monitors.../QSMONPERF.pdf

    Just match these up with modelines from above, eg,

    1600x1200 @ 75 Hz would match with:

    1600x1200 @ 75 Hz (VESA X-Server) HSync: 93.75 kHz
    ModeLine "1600x1200" 202.50 1600 1664 1856 2160 1200 1201 1204 1250 +HSync +VSync

    Looks like Jade has already been there.
