Cory, Although both LProf and ArgyllCMS create and use CGATS files there are differences between the ArgyllCMS and LProf measurement sheets in terms of how the data is represented. Also the CGATS code in ArgyllCMS and LProf is different and ArgyllCMS does put some things in some of it's CGATS files that LProf does not handle very well. Actually LProf CVS should work fine with the DTP-92Q to generate it's own measurement and calibration sheets as well as creating profiles with a VCGT. I have tested it with a serial DTP-92 as well as a Huey, EyeOne Display 2/Lt and a Spyder 2. It should also work with the DTP-94, EyeOne Display, EyeOne Pro and SpectroLino meters as well. But as far as I know these are untested at this point. However the algorithms used to create the video card LUT calibration curves and to do the display profiles in LProf are currently on the simplistic side compared to ArgyllCMS. But these will still result in significant improvements to the display calibration for most users as well as useful display profiles. As a side note for those interested in getting a measurement device my current recommendation for those who want to do this but also want to minimize the cost is to get a Huey (around $50 plus shipping on ebay). This device works nicely with both LProf and ArgyllCMS and only has a few minor issues. The most significant of these is that it can give false readings of dark patches when there are high levels of ambient light. The solution is to calibrate and profile in a dim or dark room. The other issue is that the ambient light sensor does not correctly report the color temperature and always reports 5001K no matter what kind of light you are sampling. Of the meters I have tested I like the EyeOne 2/Lt the best but it is more expensive than the Huey. Since ColorVision has a very bad attitude toward the open source community you should stay away from their products.
