    Hardware specs for RM PMA 1407 monitor

    Does anyone have any info on this monitor?

    I'm trying to set it up on a old Dell PC converted to be a thinclient with Thinstation. However the Xorg.0.log complains the monitor does not support DDC and cannot get it to run in anything other than 640x480. Here's the relevant snippet from the Xorg.0.log

    Code:
    (II) TRIDENT(0): VESA VBE DDC supported
    (II) TRIDENT(0): VESA VBE DDC Level none
    (II) TRIDENT(0): VESA VBE DDC transfer in appr. 0 sec.
    (II) TRIDENT(0): VESA VBE DDC read failed
    (--) TRIDENT(0): Revision is 106
    (--) TRIDENT(0): Found CyberBlade/i1 chip
    (--) TRIDENT(0): RAM type is SDRAM
    (--) TRIDENT(0): Using SW cursor
    (--) TRIDENT(0): VideoRAM: 8192 kByte
    (--) TRIDENT(0): TFT Panel 1024x768 found
    (--) TRIDENT(0): Memory Clock is 57.27 MHz
    (==) TRIDENT(0): Min pixel clock is 12 MHz
    (--) TRIDENT(0): Max pixel clock is 230 MHz
    (II) TRIDENT(0): Monitor0: Using default hsync range of 28.00-33.00 kHz
    (II) TRIDENT(0): Monitor0: Using vrefresh value of 60.00 Hz
    (II) TRIDENT(0): Clock range:  12.00 to 230.00 MHz
    (II) TRIDENT(0): Not using default mode "640x350" (hsync out of range)
    (II) TRIDENT(0): Not using default mode "320x175" (bad mode clock/interlace/doublescan)
    (II) TRIDENT(0): Not using default mode "640x400" (hsync out of range)
    (II) TRIDENT(0): Not using default mode "320x200" (bad mode clock/interlace/doublescan)
    (II) TRIDENT(0): Not using default mode "720x400" (hsync out of range)
    (II) TRIDENT(0): Not using default mode "360x200" (bad mode clock/interlace/doublescan)
    ....
    ....
    ....
    ....
    (II) TRIDENT(0): Not using mode "800x600" (no mode of this name)
    (--) TRIDENT(0): Virtual size is 640x480 (pitch 640)
    (**) TRIDENT(0):  Default mode "640x480": 25.2 MHz, 31.5 kHz, 60.0 Hz
    (II) TRIDENT(0): Modeline "640x480"   25.20  640 656 752 800  480 490 492 525 -hsync -vsync
    (==) TRIDENT(0): DPI set to (75, 75)
    I really need it to run at a higher resolution. I specifically need the horizontal and vertical refresh rates.

    Nothing here sorry, might be worth comparing it to a monitor of the same size/rough age and nicking those values...

    My defaults are fairly sane, they are as follows.

    Code:
    SCREEM_RESOLUTION="800x600"
    
    SCREEN_COLOR_DEPTH="16 | 8 | 24 | *"
    
    SCREEN_HORIZSYNC="30-64 | *"
    
    SCREEN_VERTREFRESH="56-87 | 60 | 56 | 70 | 72 | 75"

    Screen is mispelt, maybe its not being read because of that?

    Ah so it is, I fixed that, but it doesn't affect anything.

    Might have to resort to trying random numbers. :P

    I tracked down an windows inf file for the monitor (and some other RM monitors) here:

    http://fsc.feis.herts.ac.uk/images/198/mon_rm.inf

    Seems it's known as an 'RM14' ?

    Anyway, if you know how to read inf files, there's a section on refresh rates further down. So I'll give it a go.

    Should set it straight!

    Fingers crossed.

    Indeed. There's info here on how to 'decode' these lines.

    So I'm all set it seems.

    Works fine now. Here's my thinstation group file for the monitor, if anyone else needs it. Just uncomment the resolution section you want if you don't want to run in 800x600.

    Code:
    # --- RM PMA 1407 (aka RM14) Monitor configuration
    
    #SCREEN_RESOLUTION="640x480"
    #SCREEN_HORIZSYNC="31-32.5"
    #SCREEN_VERTREFRESH="59-60"
    
    SCREEN_RESOLUTION="800x600"
    SCREEN_HORIZSYNC="37-38.5"
    SCREEN_VERTREFRESH="59-61"
    
    #Alternate 800x600 Settings (72Hz)
    #SCREEN_HORIZSYNC="47.5-48.5"
    #SCREEN_VERTREFRESH="72-72.5"
    
    #SCREEN_RESOLUTION="1024x768"
    #SCREEN_HORIZSYNC="48-60"
    #SCREEN_VERTREFRESH="59-61"
    
    #Monitor doesn't support DCC
    X_DRIVER_OPTION2="noDDC On"

  13. Thanks to Geoff from:
