Just bought it and it’s 100% flicker-free as advertised. Manufactured on November 2019.
I haven’t noticed any flickering at all (I am very sensitive to it), so I did a simple test:
Prepare black screen with 1px wide vertical line in the middle. Set camera (RX100 v1) to manual mode (iso 200, F2.5, manual focus) with exposure 1/25. Quickly drag camera horizontally and shoot while dragging.
On U3219Q gray rectangle is perfectly even so light has the same intensity throughout the shot (brightness at 30%): https://ibb.co/J3bYQmn
If your statement would be correct in 1/25 of a second, at 200 hz there should be exactly 8 brighter and darker vertical areas evenly distributed over gray rectangle.
