Aquila The input doesn't make a difference for me, unfortunately!
Fakir35 In my own case I can use the Asus VS247H-P 24" monitor all day without strain, it is my main monitor that I'm using right now and have been using for the past 10 years. Three points to consider though: (1.) It is 6 bit + FRC (FRC = temporal dithering!- gasp!); (2.) I've tested it myself and it does use Pulse Width Modulation to control brightness (PWM- gasp!); and (3.) It simply doesn't have gaming monitors specs- it's a basic 60 Hz 24"TN panel with no VRR. That being said, it functions just fine, the response time is probably 1-2 ms. Interestingly, the fact that this monitor uses a form of temporal dithering and PWM has always made me discount flicker as being my main issue, however, after having a painful recent experience with a 4k pixel-shifting DLP projector that uses a lamp (no LEDs at all!) but does flicker, I'm wondering if newer LED backlights have some other kind of inherent imperceptible flicker. Also I've experienced an LED desk lamp that caused the same exact symptoms- so I'm wondering if maybe the LEDs themselves now pulse in some way that they didn't use to.
