Continuing with the clean out - I have a Colourvision Datacolour monitor calibration device. From memory its a Spyder.
I haven’t used it in many years and don’t have the software for it but have no reason to believe that it won’t still work. I use a Mac so plugging it in and testing it seems to be an issue
The current models sell for over $200. If you think you can use it and would be willing to pay what you think is appropriate, it’s yours. Buyer pays shipping or pick up from Inner West, Sydney.
