Re: Getting the right monitor profile

Very odd!
Video ringing is usually due to 'overshoot' of the waveform due to high
capacitance in the cable, or reflections back down the cable due to poor
impedance mismatching, neither of which should be a problem with modern kit,
unless you've added an extension to your video lead.
The only alternative which comes to mind is if the same sort of thing is
happening on the databus with your new RAM, but that would usually result in
system crashes, unless the problem is in the I/O buffers on the video card
itself. If your video system uses shared RAM on the motherboard, consider
swapping it with a controller which uses on-board video RAM.
You might also try moving the video cable, and checking that it's attached
securely. Using a lower refresh rate might also help, as it reduces the
bandwidth, but you might notice some flicker if your lighting is
fluorescent. This may also help if the cause is overheating chips on the
video controller.

curiouser and curiouser.  I use a 1GHz Athlon and W2000 Professional.  I
used to get a profile association problem message, ('could not find
device')and the profile would not show up in the appropriate directory(s),
but was clearly operating. That went away sometime after i got the newer
Photocal update, and the profile showed up correctly in the /WINNT etc.
folder, and could be associated correctly under Devices.  Then i got the
Wacom interaction problem, which is easily solved.  No specific problems
now, except i get video ringing since i installed more memory.  seems to be
associated with heavy disc hitting.  It starts out clean, then gradually
accumulates, and is often clean again once i do a cold reboot.  I checked
all the video setting that are civilian accessible, and recalibrated the
monitor profile (i use 5000K and have no trouble getting the individual guns
set, and achieving 85-95 lumens per instruction).  The ringing doesn't seem
to affect anything except my poor annoyed eyes.  Any chance this is a timing
issue too?
