Again, how do you measure Native Gamma using Spyder2 Pro? You seem to be using it and that's exactly what I'm trying to achieve right now.

Here - put this into your \Colorvision\Spyder\Targets -folder:

[a href=\"http://www.loadusfx.net/linear.tgt]http://www.loadusfx.net/linear.tgt[/url]

... and calibrate using that as a target. It's D65 G1.00.

Edit:
Or, with the Pro version I guess you can make it manually too?

Edit Part II:
OR: Are you referring to the 2.5 gamma? You really don't need to measure it - it's a standard measure for CRTs. Engineering tweaks. You can safely calibrate your monitor to 2.2 to have it ready for sRGB or AdobeRGB.

I meant to measure Native gamma. I know that I can put 1.0 as a target.

I mean how do I know what's my monitor's Native gamma? I have several LCDs and CRTs.

Haa. Well, you'll have to do a basic visual test using a gamma test card (can be found all over the net) one place is here: [a href=\"http://www.aim-dtp.net/aim/evaluation/gamma_space/index.htm]http://www.aim-dtp.net/aim/evaluation/gamma_space/index.htm[/url]

The estimate is never accurate, ie. I tried to figure out the native gamma of the BenQ FP731 monitor (really REALLY poor quality monitor although recommended by micro$oft) and when the viewing angle of this monitor is really narrow the gamma was extremely difficult to evaluate. I came up with 1.5 - 1.7 being close to the native sRGB setting (in the settings menu).
