2854.0. "VRC16 and interlaced" by WOTVAX::HILTON (Save Water, drink beer) Tue Mar 18 1997 07:39

    I'm trying to use a VRC16 with a Orchid Kelvin video board. I can't get
    1024x768 in Non-Interlaced mode, it always switches to interlaced.
    
    I can't find anyway under Win95 to force this to use NI, the card
    manual says it supports 1024x768 NI.
    
    Any ideas?
    
    Cheers,

    As well as the capabilities of the video card, Win95 also looks at what
    (it thinks) the monitor is capable of.  Microsoft doesn't ship
    information files for the VRC16, so you must be using either a
    home-grown info file, or telling Win95 that the monitor is something
    else.  Check whether whichever info file you're using allows
    1024x768NI.

	There is a VRC16.inf file in the Windows95 notesfile. It's in
	Note 905 someplace. Use this to tell Win95 what the monitor is
	capable of.

	Right-click background, Properties, Settings Tab, Change
	Display Type, Change Monitor Type, Have Disk, etc.. Point
	it at the VRC16.inf file.

    Be a bit careful with this file.  There were two different versions of
    the VRC16, which differed in their bandwidths.  The VRC16.inf in the
    conference only describes the newer (better) version, and if you usew
    this file with an older VRC16, you might end up driving it faster than
    it can handle (which isn't a good idea with the VRC16 - it seems to be
    quite easy to kill it).
    
    If you do have an older VRC16, you'd be safer editing the VRC16.inf to
    reflect the true capabilities of your monitor.  The format of the file
    should be fairly obvious, and you can probably find the purchase specs
    of the original VRC16 in the DECstation conference.

    I tried the .inf, it didn't make any difference.

    Well I found the specs, I had the -HA model, and it appears the
    settings used in the .inf that's floating around are way to high,
    setting them lower means I can now run at 1024x768 with 70hz.
