I used the Asus PA248Q supplied profile as a starting point.

I think that is where the person I'm trying to assist made the error. They were using the i1 to first re-calibrate the hardware (which worked fine) and then created a profile without using the supplied profile as a starting point. When they then loaded the i1 software to create a profile it completely messed what was displayed on screen. If the hardware is calibrated correctly I'm not sure there's even any need to produce a custom profile as the sRGB and aRGB modes would then be accurate using the canned profile. No? I really prefer my Dell monitors and its custom i1 software calibrates the monitor hardware AND also creates a custom profile that's saved in the appropriate system folder. The documentation suppled with the Asus ProArt montor is lacking detail. Russell
