Mike,
I know your opinion about calibrating:
But I have after long thinking about it, bought me a Spyder2Pro.
I have 2 systems with 2 DVI-LCD monitors.
One is a Medion system and the other is a made assembled my self.
Thew monitors are also different.
In the past , I have spent a lot of time to make both monitors visible the same.
Why ? Because I have on both systems nearly the same photo's.
they look different on both systems.
I am experimenting a couple of days now with the spyder to make both monitors visible look the same.
But I come together, but I stay See differences./
This also when I gave the same input for dark luminance  and black luminance on both calibrations.
Also the same Kelvin.

I have place a message on several dutch photo newsgroups, but I get no response.
What can be the course of the differences?
They look , nearly the same but not on the whole.

I know from the early days , When I was electronic hobbyist, that CRTs have different phosphor qualities.
Is this on some Way also with the LCD pixels too?

I think you know much of this calibration phenomena !

By the way , seen of a electronic standpoint, the Spyder2 Pro is extremely expensive.
There is only a small chip in site with a opal glass deck.
I think the really cost of this thing is about 25 dollar or so, perheps less, when you order 10.000 or more.
Then there is also the software.
I pay for the whole thing 298 euro.

Do you now to handle on the best with 2 different monitors and the photo's look the same ?

Hi Frits,

First, experiment with any manual settings that may be available for the two monitors.  Monitor calibration software generally trys to match the color and saturation, but not the overall brightness.  If your monitor provides manual adjustments, see if you can use them to bring your two monitors closer in line with one another.

Mike , I have experimented in the past a very very lot times to make the monitors visible with a lot of software prgr's.
It not succeeded.
Now I bought Spyder2 Pro.

the principle of the chip in site the spyder is very cheap.
It can only see light, no color at all.
The prgr generated a set of black and whites an of course a set of colors.
But the chip sees only light. That he measures. and gives output in candelas.
You can also set the program to  special  input candelas for black and white.
When I do that for instance black 0.80 and 134 for white on both machines and with the same gamma and whitecolor and 6000 gr Kelvin, then the two machines or Monitors must give the same output in my opinion.
But it is not so.
I see differences.
When i do it manually, what you suggest, then I have that done a lot  of times in the past.
When you do that you change  everything.
The gamma curve and so on.

to get monitors give the same output is difficult.

Therefore I made a comparing in maximum and minimum setting of both monitors.
See picture.
the problem is , when you set for instance one monitor to a blackpoint of 0.80  the same cannot reached on the other.
the Medion monitor can reach about 0,65 on blackpoint and the other monitor to 0,94.

the strange thing is, that to make both the same, my decision was a blackpoint of 0,63 ( o,64)
But the whitepoint can 't reached high. The maximum is  about 114 with one monitor.
It cost me a lot of time.
the medion monitor is relative new and few used, the other monitor the Flattron is used 8500 hours.

The last part of your table shows that you have very similar black and white points.  Does this mean that you have solved the problem?

Mike,

till know i did n't know yet.
It was late yesterday. I look totday  to the two monitors! I let you know.

Mike,

For comparing I used the computergenerated Gretag-chart. And comparing both pictures I can say it is about 98 % right.
I see a slightly difference, but I think with working with normal photo 's I do not see it.

mike,

I made the previous picture bigger!

Is the picture available online?

I made the picture bigger or changed the picture of reply 3!
