qb74 not some random videos.
Main issue of modern monitors not in dithering or FRC, issue is vcom adjustment which prevent pixel sticking
Looking in my vids you will see different vcom in each monitor, you dont need microscope to record vcom: 60hz monitor, 60p camera and good zoom is enough ( the main rule - camera should gives you high res picture and much more FPS record than monitor did, better to sync record speed )
There are many influencing factors that can be listed, but to check each of them, you need to take measurements.
I believe that monitor problems can be reduced by following these rules:
1) No more than 60/75Hz (I saw a hard vcom in all high-frame rate monitors)
2) Without HDR and excessive brightness (<= 250 nits)
3) Year of manufacture 2014 ... 2020
4) IPS or VA panel does not matter
5) wled backlight without quantum and other technologies of extended coverage, giving sRGB coverage of about 90 ... 100%
6) Monitor coating - very light matte (hard-matte blurs the structure of RGB subpixels and strains the eyes)
7) Almost all monitors are now without low-frequency PWM (> 10 kHz)
8) Almost all monitors have a blue peak at 446 ... 460 nm, this is safe
9) BASIC color temperature - around 6500k, when looking at the monitor there should be no be cold shades
10) DP or HDMI port - does not matter. Both can dither, depending on the EDID settings
