BenQ’s latest monitors which come with the bluelight function are apparently great for eyecare and have the ability to reduce the risks of experiencing headaches due to prolonged eyestrain from staring at PC screens for long hours at a time. Besides that, one of BenQ’s flagship models (the BenQ EW2440L) does not come with the inferior PWM technology. One of their best monitors would be the BenQ XL2420Z, which boasts a response time of less than 4 ms when cranked up to 144 Hz of refresh rates. Of course, there are other similar gaming monitors that perform just as well and you can use this table to compare your options. Just in case you didn’t know, PWM is most commonly used in lower cost LED monitors, which essentially turns the backlight of the display on and off periodically in order to maintain a lower brightness level that supposedly helps reduces eyestrain.
