The following are non-pursuit photo compilations of the Test UFO Ghosting test with each monitors back-light or brightness setting set to the maximum.  The AOC and Sony are completely PWM/Flicker Free while the Samsung uses low frequency PWM when the back-light setting is set to 49/50 and lower.  LED PWM Dimming or flicker reduces motion clarity and makes content in smooth camera pans appear to judder and blur significantly more than PWM/Flicker free displays like the AOC and Sony.


In this comparison the Sony is the fastest except in the top UFO which shows a bit more ghosting than the AOC, which along with the Sony has vastly faster pixel response times than the Samsung which along with the others is overshoot ghosting free, but has very slow pixel response times resulting in very obvious color streaking and smearing of black, brown and grey shades.  Even when the back-light is set to maximum to prevent PWM blur, the Samsung offers very poor overdrive performance since it has very slow pixel response times, especially compared to VA panels in similarly priced 32" 4K VA panels like the BenQ EW3270 which is PWM/Flicker Free.

The Sony 43X750F offers both overshoot ghosting and PWM blur free overdrive, and fast pixel response times competitive with the fastest 60hz AHVA/IPS/PLS panels like the Acer XB321HK I tested in 2017, AOC AG271QG, and unlike almost all TV competitors, the Sony is free from PWM blur.  The Sony still suffers from a bit of color streaking, but only slightly more so than the fastest 60hz TN panels like the BenQ Zowie RL2460.
