Barry, It is worth knowing about the "internal calibration" capabilities of this monitor. If, indeed, this monitor has built-in LUT capabilities, as Eizo or NECs, it would be worth experimenting with using that first, and only use the Spyder to build a ICC profile *on top* of that calibration. It's been a while since I used the Spyder software myself, perhaps there is a some kind of option to test gamma or other calibration scheme? So that the user would be able to judge how good is the monitor calibration to begin with. I believe Argyll offers this capability (among its extensive set of analytic capabilities), if it can't be found in the Spyder software. My two cents... / Roger -----Original Message----- From: colorsync-users [mailto:colorsync-users-bounces+graxx=videotron.ca@lists.apple.com] On Behalf Of Barry Rudick Sent: Monday, March 26, 2018 5:01 PM To: ColorSync Users Mailing List <colorsync-users@lists.apple.com> Subject: Asus monitor calibration I think you should start over with the Spyder. I have calibrated many Windows driven monitors. The first thing to do is turn off all monitor control software, or better said perhaps is to put the monitor in it’s native state. If you can determine how to do that then running SpyderPro or equivalent with the Spyder Calibrator you will get to where you want to go. The controls on the monitor should allow you to choose which state you want. If you can put it in native state with no internal calibration that would be ideal. The calibration will be supplied by the Spyder calibration and the ICC profile created will be the one to point the system to as the monitor profile. You can not have two profiles working at once. It is important to set the parameters as: brightness between 100 and 140 depending on how bright your office is. The software will measure the brightness and while accessing the monitor controls you adjust the brightness down until you get a very close confirmation.
