Spyder with new nVidia drivers

2007-01-27, 10:17 pm

I just installed new nVidia drivers on my machine (Dell
XPS 600 with XP Pro, nVidia GeForce 7900 GTX, dual 2405
flat panels).

I chose, initially, single display to have both monitors
treated as a single large monitor (nice to have the task
bar span both screens). This caused Spyder to lose its
profile, as the profile was not associated with the dual
monitor setup.

Do I need to go back to the dual display mode to have spyder
work, or would a new calibration in the single display mode
associate itself correctly?

Hope this was not too confusing, I have certainly gotten a lot
of very useful help here.

Thanks,

Hi.

I can't quite remember, but there is something in the Spyder instructions
about it not being able to profile 2 monitors on a Dual Card, except in
Macs.

If you need both Monitors profiled individually, you need to use 2 Cards.

What worries me is using 1 Profile for 2 Monitors. Can you be sure they
both handle colours in an identical manner. I know they are both the same
model - but manufacturing tolerances ain't all that good.

Yes, because Windows only uses one profile per video card.

This question was more about the interaction between nVidia driver settings
and Spyder. The drivers allow you to treat both monitors as one large one,
which I initially did, but that broke the association between the profile and
the monitor.

I guess I will try to calibrate in that mode, and see if the Spyder target is
on just one monitor (or big enough on one) to properly calibrate that monitor,
and to see if the new profile remains associated with the monitor.

I am good just having one, as I can have the actual image there, and use the other
for palettes and email...

Mine are definitely different. To the naked eye it is quite noticeable.

Hi again.

When you say using both as one big one, I presume you mean "Extend My
Desktop onto this one" in 2nd monitor settings.

The instructions are not exactly specific. It is very clear that it cannot
profile both individually, but not clear if the profile will be applied to
both at the same time or to none.

I have 2 Monitors and 2 Cards. The second card is a 32Mb cheapo.

Maybe, maybe not. I would not expect two completely different monitors to
match. OTOH, if the monitors are the same model, made at about the same
time on the same assembly line, etc, I would expect them to match within a
few percent. The remaining difference, if any, can be accommodated using
the monitor's own controls.
