    I'll repost my question to this page so that it was easy to understand what I am talking about Smiley Happy

    The PWM is for the signal but the backlight does not use PWM.  The backlight uses 5V DC.

     

    Does H226HQL have PWM in backlight dimming/regulation?  No


     The thing is some monitors use "hybrid solution" for brightness regulation:
    Eizo EV2336W: "PWM free down to 20% brightness, but used at 200Hz below"
    Dell U2413: "No PWM down to 20% brightness, but used 19 - 0% at high 8750Hz"

    What about H226HQL bmid? Is its backlight PWM free for 0-100% brightness?

     

    I would like to get an answer because I have severe myopia and I want to make sure this monitor is as safe for the eyes as possible Smiley Happy

    Phen1, I don't see where your uncertainty lies.  Assuming the Acer engineering people are telling the truth (and why would they not?) there is no PWM used in backlight dimming/regulation.

     

    I've been using the monitor.  I too have a visual impairment that requires me to be close to the screen.  I have to use it at low single digit brightness -- I think almost any sensible person would.  It does seem to be a little easier on the eyes than my previous LCD monitor.  Such things are hard to tell.

    This monitor has a glossy screen.  I do wonder what the material is.  Not likely to be glass.  Is it plexiglass?  Polycarbonate?  Some other plastic?

     

    This is not just curiosity.  I can easily imagine an arrangement where that information might be important.

    Since I own one, I can say for sure that it is plastic of some sort. I know of no way for me to determine the type of plastic, but I do worry a bit that one day it might need to be cleaned and some plastics are extremely easy to scratch even with a very soft cloth. So far I've been using air to clean it since I only needed to get rid of dust.

     

    And using the online chat/help thing here is of no value because they told me it was glass, which it is not.
