I purchased a Display Pro HL a month or so ago to use with ColourSpace. It seemed to work pretty well, but recently it's been providing inconsistent results. I measure a patch, then measure it again and get a rather significant difference. I did a 21^3 profile yesterday and several of the measurements were significantly out of line with what I had measured on the same device previously. Is there any way to check the device? I'm also contacting Xrite, but it's much harder to separate the performance of the probe vs the performance of the software. Any suggestions would be appreciated.

You can use 'Measurement Log' to repeatedly measure the same patch, and record the results in a .csv file.
But, any variation is either a wrong setting for the display being profiled, such as not enough Extra Delay, or the Integration Time set too short, or a defective probe.
It cannot be an actual issue with ColourSpace.

I figured it wasn't actually colourspace, but wasn't sure if it could be a physical problem with the probe (or how to figure that out) or something else. The timing makes sense. I'll check that.

Thank you
