Crazy contrast ratio result in report on calibrated display

[mat a]

Hi

I have the following monitor with a contrast ratio of 3000:1

https://www.benq.com/en-ap/monitor/stylish/gc2870h/specifications.html

I did a report on uncalibrated monitor after resetting its settings and it came back with a contrast ration of 5100:1

I have done the test several times and there are not any dynamix brightness or contrast settings enabled in the monitor

Many thanks

Disable dynamic contras ratio on OSD, try again. Usually you want a device that behaves always the same.

Dynamic contrast is off (if on, brightness and contrast are not available).

Could my profile correction be wrong? Displaycal seems to overestimate the contrast ratio on both my monitors…

5000:1 on the GC2870h (a 3000:1 panel) and 1250:1 on the GL2760h (a 1000:1 panel).

Very confused.

Thanks
