3690.0. "Gray Scale Question" by CIM::GARTNER (Jack Gartner) Mon Nov 19 1990 14:46

       I've a problem with the Startup Screen (the initial DECwindows
       screen that shows up before you login) that I hope someone can
       help me with.  I'm using a black and white monitor.  When I
       modify my DECW$PRIVATE_SERVER_SETUP.COM to turn off color
       (decw$color == "F") the Startup Screen turns a washed-out shade
       of gray (with decw$color set to T, it looks OK).  Does anyone
       know how to modify the gray-scales of this screen?

       
       Thanks,

What kind of hardware is this?  A GPX or an SPX?

Also, what is washed out?   The login box, the logo, or the funny fishscale
background?

I think that the fishscale uses BlackPixel and WhitePixel, so I don't understand
why that should be strange.  The logo etc, on the other hand allocate colors.
If you tell the server that it is a grayscale unit, it will convert color
requests to grayscale requests via the NTSC algorithm (i.e. a weighted average
of the RGB request is used for the gray).  That could very well end up being
some sort of pale color.  If the contrast is poor and hard to read, you should
probably QAR it.

    I've seen this particular system, so I'll add more info.  It's a VS2000 with
    4 plane graphics board, but with a monochrome monitor.  It's got decw$color == "F"
    and decw$bitonal == "F" in the private server setup file.  Running XCMAP on
    this system shows color map 0 as black (0000,0000,0000), but color map 1 is
    not white, it's gray (7777,7777,7777).  Running the customize window option
    from session manager shows the single color selection slider box where the
    16 shades of gray can be selected.  We've looked all over for something
    that munges color map 1, and can't find anything.  This is further complicated
    by the fact that this system was created from an image backup of another
    system on which everything works as expected.
