Hi All, I'm new to display calibration. For the longest time I have wanted to calibrate my Panasonic TX-P42ST50B plasma television, but the expense has been putting me off. I will be purchasing a 27" iMac soon and already own a mid-2012 Retina MacBook Pro. With at least three devices to calibrate I have decided to take the plunge. After considerable internet research I have settled on buying an i1 Display Pro, specifically from here http://www.nativedigital.com/xrite-i1-display-pro/ because they are one of the few retailers that list it's software compatibility. I understand the difference between the retail and OEM versions of the i1 is what software they will work with. I have read direct conflicting reports from users about what software works with what, so if you can enlighten me from your own use of the i1 please do. What software should I use? It would need to work with both plasma televisions and my iMac/rMBP displays. I would like it to be easy to use but with all the necessary readings (I understand this is colour, grey scale and gamut). My preference would be a native OS X application but I can use Windows. It would need to be free or very cheap, I am at the upper range of my budget with the i1. The i1 I am looking at includes the (X-rite?) i1 Profiler software. I am also considering ColorHCFR because I have found a guide here http://www.curtpalme.com/forum/viewtopic.php?t=10457&start=0&postdays=0&postorder=asc&highlight= without which I doubt I could figure out how to use it unless it has a good manual. Another option would be CalMAN ColorChecker. For test patterns on my plasma I am looking at either the 2nd Edition Spears & Munsil HD blu-ray or HD Basics DVE. Please feel free to comment on either of these choices and their ease of use with your recommended software. Thanks.
