That's not input processing.
Example of a 9 year old "office" monitor: https://www.prad.de/testberichte/test-monitor-dell-u2412m/6/...
Example: https://www.rtings.com/monitor/tests/inputs/input-lag (Scroll down to the non-gaming monitors)
The gray-to-gray response time for the physical pixels is in the neighborhood of 2-4ms, so the additional latency comes from the processing.
