I've tried to solve this question on my own but I haven't been able to get a solid answer.

I'm looking at a few Asus monitors that boast "flicker free eyecare technology." Now to me, "flicker free" means no PWM, however according to measurements i've seen from RTINGS these displays are still using PWM dimming, just at a very high frequency. (Far above 2000hz, i've read 20Khz) For their part, RTINGS says the frequency is so high that there's no flicker, is that really true? Asus refers to this page on their site that has info about their eyecare monitors: https://www.asus.com/Microsite/display/eye_care_technology/

This is where it gets even more confusing. Under the Flicker Free tab it says: "ASUS Flicker-Free technology uses Smart Dynamic Backlight Adjustment to reduce flicker for a comfortable viewing experience. Smart Dynamic Backlight Adjustment avoids low brightness levels that lead to high-speed LED backlight flashing."

Which means what, exactly? To me this sounds like some kind of automatic brightness adjustment that just prevents the display from getting dim enough to cause flicker. The wording on this is poor and I can't find out any specific info on what this "smart backlight adjustment" actually does other than what i'm assuming from the name.

I just bought an Asus VG27AQL1A with that feature. I haven't noticed any flickering with general desktop usage or gaming.

I am returning it though because with displayport connected to a 1080Ti, it is so slow when booting the computer that you never see the BIOS screen and the motherboard vga error light comes on and stays on. If you want to enter BIOS, you have to use the home connection. It wouldn't be as big of a deal if I didn't have a tempered glass case. It works really well, but for almost $500, I shouldn't have to compromise on crap like that.
