CRTs used to always give me headaches, so LCDs won out personally.
85 hz on crt is the non-flashy point..
LCDs don't flash, but due to ULMB, it turns out Flashing is necessary, so we need to flash LCDs now at 100+ hz..
But non-PWM monitors don't flash amiright? Or is some sort of flashing inherent to the LCD tech? Anyway, my Iiyama's were between 100-120 hz and that felt better than most LCDs
CCR does not flicker
PWM flickers.
BUT..... the issue is actually not as pervasive, because MOST people do not see the flicker of PWM monitors.
It depends on what rate the pulse is being pulsed at..
@ 120hz, it's not really perceptible.. on moving images..
__in fact, the ULMB operates by pulsing, and it Clears up the moving image by going dark during the lcd transition states where the color is WRONG, removing ghosting and pixel transition blur..
@ below 100hz, the pulsing is a bit more obvious, and cannot be utilized for ULMB.
ULMB is necessary for clear motion clarity..
For office work, ULMB is not necessary, therefore, if you turn the monitor backlight all the way up , the pwm stops.. In this way, the monitor can perform double duty..
But VERY FEW people see flicker of PWM, it's those same silly people who says OMG my keycap is slightly bent, who are championing anti-pwm monitor..
IF YOU didn't even know what PWM was, odds are you're not someone who is susceptible to pwm-flicker, because assuming you've encountered computer monitors in your life prior to your new purchase and didn't notice flicker, you're in the clear.
