I managed to get my PA271W working with the USB-A (monitor) to USB-B cable (computer), with my new M4 Max Studio that arrived a couple of days ago. Spectraview II recognized the monitor and I was able to profile it with the Spectraview II software to a Delta E of 0.4, not bad for a 13 year old monitor with 14K hours!
I just saved some serious money over a new monitor.
