  • The Warm setting (and thus also the User default) might not be all that warm. It's hard to tell what the "color temperature" is. It does appear to be warmer than the default with the fluorescent backlit monitors I've used, but it might not be any or much warmer than high noon. I haven't fiddled much with it, but I did turn…
  • 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.
  • 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…
  • According to the information in the link that you provided, the H226HQL (they got no more specific than that) was PWM free for the full brightness range.
  • Acer-Tommy wrote: * The H226HQL uses 5V DC for the back light and it is not related to the brightness. Brightness is controlled by the OS. This I do not understand. My assumption was that in such a situation the backlight was dimmed or brightened by altering the DC voltage. Are you saying that no matter what the brightness…
  • Hooray! And two kudos expressed. (And interest in learning more about PWM in monitors stimulated.)
  • I haven't marked the thread as "solved" because I haven't been able to reconcile the fact that two apparently reliable sources have come up with contradictory statements. There's got to be a deeper story somewhere. Datacons seems to have a probing tack.
  • Thanks Acer-Tommy for looking into this. I must say I'm disappointed, and confused also. I thought I'd found something that might be helpful as far as preserving eyesight.
  • I found this article by a site that tested the monitor thoroughly and ascertained that, indeed, it did not have PWM. (Google Translate is at our disposal.) Encouraged, I went ahead and bought it. However, it occurred to me afterwards that the article was written in February and the monitor I received was manufactured in…
