Dual Calibration Step by Step

Dual Calibration Step by Step

2007-04-18 by rasrtw

I have a dual Dell 2007WFP monitor setup with an NVIDIA Quadro PCI-E
Series video card.  I recently purchased the Spyder2Pro.  I purchased
the calibration device in hopes of matching the two monitors.  I have
gotten them close but not as close as I thought possible.  I have read
through many of the discussions on the Spdyer2Pro and dual monitor
calibration.  Nearly all of them are geared toward the hardware.  Is
there good documentation of how to actually perform the calibration
for matching two side by side monitors?  I don't see anything specific
in the provided documentation nor the software interface pertaining to
monitor matching procedures.

Any help or suggestions are greatly appreciated.

Cheers,
Rob

What are you envisioning beyond whats there? You define a custom target that both can meet, with a black luminance value matching the weaker (higher) black, and a white luminance value below both native whitepoints (way below, if they are bright LCDs). Then you calibrate both to this target, and you are done. Beyond that its a matter of using a color managed application to display two copies of the same image on both screens. If the gamut if each is different, then there might be a few fringe colors one can reach, but the other can't. Otherwise, thats about as matched as monitors get. Given that most LCDs have few controls there is little tuning that can be done.

I just did this, but you should have it easier.  I have a Dell 1907FP 
and HP LP2065.

Pick a monitor to be first.  Process it to your taste.  It is a little 
easier, I believe, if you use measured luminance.  That means you will 
need to determine appropriate luminance levels.  I turned on ambient 
light measurment to see what the software would recommend.

Based on my lighting, I chose black level of 0.5 candela/square meter 
and white level of 150.  Calibrated to these levels and desired color 
temp -- I chose 5800 K.  Then, calibrated the other monitor the same 
way.  Since your monitors are identical, this should not be a problem.  
After calibrating, click on Tools then Information to see the quality 
of your calibration -- check the delta-E values, shoot for between 1 
and 3, closer to 1 is better.

If you Google this you will find some sites that can help.  Search for 
dual monitor calibration.
