I am a user of an iPro and was using Eyematch on Win7 Pro. However, this software (latest version here: http://xritephoto.com/ph_product_overview.aspx?action=support&id=1014) does not work on Win 8.1. I tried using iProfiler but it doesnt even see the colorimeter. So I tried ArgyllCMS 1.6.1 and the dispcalGUI front end. It did the calibration fine but i didnt get any icc or icm files out of it. I did get a .cal file and 2 batch files- one named XL2420TE.all.cmd and another named XL2420TE.dispcal.cmd What do I do with these files and how do I get an icc/icm file? Sorry for the basic question but the argyllCMS website is sparse on helpful hints. Before you go nuts telling me my monitor is not a good one, I realize the BenqXL2420 is a TN panel and my main monitor on my production system is a 30" HP running on win7 pro. But before i move to win 8.1 I am testing my software on another pc running on this cheaper monitor (and hoping to get a better appearrance from this aweful panel as well)
