Hardware specs for RM PMA 1407 monitor

[Geoff]

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

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...

[Geoff]

My defaults are fairly sane, they are as follows.

 

SCREEM_RESOLUTION="800x600"

SCREEN_COLOR_DEPTH="16 | 8 | 24 | *"

SCREEN_HORIZSYNC="30-64 | *"

SCREEN_VERTREFRESH="56-87 | 60 | 56 | 70 | 72 | 75"

[kmount]

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

[Geoff]

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

[kmount]

Wishful thinking

[Geoff]

Might have to resort to trying random numbers.

[Geoff]

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.

[kmount]

HKR,"MODES\1024,768",Mode1,,"48-60,59.0-61.0,+,+"

 

Should set it straight!

 

Fingers crossed.

[Geoff]

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

So I'm all set it seems.

[kmount]

Fingers crossed for tomorrow then!

[Geoff]

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.

 

# --- 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

[kmount]

Ahh, a happy ending...
