I think its possible within Windows, I made a custom resolution of 50hz with the CRU program and it seems to work, I would need someone else to confirm. CRU settings below:
I did play a 50fps video on YouTube and it looked smooth and clear:

Note this mode flickers even more than the 60hz mode! The 60hz mode flicker doesn't bother me but I think this would bother me using it an extended time.
The pulse width adjustments are still available in this mode too.
Checked UFO test and it confirms its 50hz, it also says on the Acer OSD that its running at 50hz.
Thank you!!
I'm selling current ViewSonic monitor... Then I'll buy this Acer monitor in this month...
Best regards.
I wouldn’t buy it for the 50hz mode, I can see why it’s not officially supported.
It has a lot of image retention.

If it's "hardware" strobe, LCD doesn't suffer burn-in because LCD doesn't use flickering. LED backlight is (very) cheap but up to 60k hours of lifespan while LCD is very expensive but fortunately, between 100 and 150 years of lifespan.

Just to clarify, I meant image retention, not burn-in, which is a bit different.
What I'm seeing is that desktop icons stay faintly visible as an overlay when watching video, and it takes a while for them to fade away.

Ok. But 50Hz + HW strobing ( = LED strobing ) won't harm LCD screen because the temperature isn't high - only cooler than 35~40 ºC. But yes hotter than 60 ºC can degrade or ruin LCD.
