I hope you get to test the M437-G0 eventually, because I was very disappointed with the headaches it can cause. The backlight PWM is much slower than the tested 240Hz. When brightness isn’t set to 100%, I can clearly see side effects. I suspect it’s 120Hz but I haven’t found a reliable way to measure that yet.
Even weirder, even with brightness at 100%, motion handling itself seems to be poor somehow. With BFI off and regardless of Film mode, I see a strong stroboscopic effect not visible on my good old Sony.
Too bad I finally installed it after the return window…
