What you probably want is a flicker-free dimming monitor, so the backlight can dim without PWM.
I cannot state how strongly I agree with this!!
I have astigmatism, and that flicker just loves to scream at my eyes!
ASUS / BenQ (they seem to really be competing against each other) make monitors with the DC dimming, and are VA panels. I'm not aware of other monitors that strongly promote the DC / anti flicker dimming like they do.
