This is a question about calibrating a Canon Realis SX80 projector using Spyder2Pro.

We (our photo club) calibrated the projector last fall and the profiles we built seemed to be an improvement on the generic profile that came with the projector.

However, we are now getting images that are high in contrast, saturated and with exaggerated reds. This is true with both an HP Windows laptop and a MacBookPro (we built profiles with each) running the projector. 

I reset everything and made a new profile for the Mac. The new profile produces images with pretty much the same problems. In fact, now the generic profile looks better than the profiles generated with the Spyder2.

Is there anyone who can offer some advice or suggest some things we could try?

The projector should be in sRGB mode. From your description, it sounds like 
somebody changed the projector's mode to something other than sRGB, such as 
presentation mode or gaming mode.

See if there is any way to reset the projector OSD controls to factory  
defaults. Or see if there is a color mode such as sRGB that improves  
the balance. Do whatever you can with the projector controls to  
improve the base state of the device before profiling.

Thanks for the suggestions.

I think I've done (almost) all of this so am still looking for a solution.

Summary:
- the SX80 is set to the sRGB mode
- the images have been converted to sRGB
- all colour settings were returned to defaults before building the profile (using the reset option in the menu -- I checked and all were at zero settings)
- the projector was using the Canon supplied profile (without adjustment) before running Spyder2Pro

Questions:
1. What are OSD defaults? (I'm assuming that the reset option does this)
2. Would using a Spyder3 give noticeably better results?
3. You suggested that manually adjusting the projector (running with the Canon supplied profile?) prior to building the profile may help -- that's opposite to the advice on page 45 of the Spyder2 user guide which advises using factory defaults. Can you explain further?
