Monitor Calibration?

Q. Can an LCD computer monitor be calibrated? I had a Spyder Pro2 and went through the whole process three times. Each time, everything turned a not so lovely shade of blue. I gave up and sold the Spyder on eBay. I have since read that you can't really calibrate an LCD monitor.

What's your experience with this?

Thanks.
I didn't think about the pressure sensitivity issues. My monitor is "nearly" upright - like about 89 degrees to the desktop - but it was resting on the screen. The directions tell you to insure contact, if I recall, but I had it over a year ago and maybe the LCD issues had not surfaced yet. Thanks.

A. The Spyder should work on an LCD. There are reviews on the we b of it working well on LCD monitors and notebooks.

LCDs are pressure sensitive, so you need to make sure that the sensor is not pressing on the surface of the screen, or anything for about a half inch around it. Alternatively maybe it was a defective unit.


The colour range of LCDs is less than that of CRTs, which is less than that of what you can see. So while you can calibrate your monitor to produce more accurate colours within the range it can produce there is no way to reproduce a really deep blue, or other highly saturated colours.

It would be very interesting for LCD manufacturers to start publishing their colour gamut figures.

Monitor Color Calibration?
Q. what type of monitor color calibration do you use, or do you just leave it alone?

A. I use the Spyder3 Elite. http://spyder.datacolor.com/product-mc-s3elite.php It has good reviews and the price is decent. It does monitors (both CRT & LCD), laptops, and projectors.

Every now and then the question "why doesn't an image look the same when I put it on a friends monitor?" or "when I had photos printed, they don't look like they do on my computer" appears on Y!A...the answer is always monitor calibration.

Some key tips on calibration:
1) have the monitor on and in use for at least 30 minutes
2) avoid direct light on the screen when calibrating (can you see any light reflecting on the screen?) I turn off overhead lights and shut the shades on the windows.
