I like it. Much more akin to the EW2440L in minimum brightness than the GW2760HS. It still is brighter than the EW2440L, and if 0 brightness was all one could tolerate on the EW2440L I would not recommend it, but I don't have to use any program to mess with the colours, and I kept the OSD contrast at 10. The first monitor I got had a dead HDMI port, so I exchanged it and now this one has bad panel uniformity, especially in 2 horizontal bands, one running through the middle of the screen and the other through the bottom. It seems BenQ does not have good QC.

It does look a bit washed out compared to the EW2440L at 0 brightness. The EW2440L really excels at giving adequate contrast at very low brightness.

Increasing saturation and gamma in the OSD might be helping.

    degen I lost track, which model are you testing right now?

      The EW2750ZL. It's a lot better than the GW2760HS but I'm thinking of returning it anyway because it still puts more strain on my eye than the EW2440L. No headaches or eyegraines but the muscles around my eye tighten up more and my eyes got redder. I'm using the EW2440L now again. It could be a brightness issue, it is brighter. Or something else, I really have no idea. In any case my monitor explorations are over. It's back to the EW2440L and my plasma TV until something better comes along... Someday....

        degen Did you, too, notice that the EW2440L's AMA option causes you eye strain? Every time I tried it I soon got some small eye strain. Maybe you still have it activated since it's on by default. Worth checking it out over time. It's in "Picture" setting, at the bottom.

            KM thank you I have turned it off. hope to see a difference. I usually try to turn off all "enhancements" but this one slipped by me.

              degen Now I bought an EW2775ZH. It has a good picture with much better uniformity of light, but it's still too bright for me at brightness 0, contrast 0, and on top of that in "dark room mode".
              It turned out the newer "Blue Light Plus" modes didn't help at all. The OSD's white doesn't change when selecting such a mode, which tells me the modes don't change the backlight diodes, like some reviews suggested.
              I'll stop buying new monitors, too. Until some promising technology shows up.

                  This review clocked the brightness of the EW2775ZH at 0% at 32.6. Higher than the pcmonitors review of the EW2750L which they measured at 19 cd/m². Difference in measuring equipment or difference in panel?

                  I kind of wish I had gotten that monitor instead. I'm stuck with the EW2750ZL because I didn't return it in time. I didn't realize I could get the EW2775ZH shipped to Canada reasonably from the US.

                  I have been using the EW2440L without AMA on and the motion blur is really bad. I have been having nausea that is triggered by rapid movement in the background of 3d games which is something I've never had before.

                    degen Happened to me, too, when playing certain games. Especially side scrolling ones.

                      Muscles around eyes are still tensing badly. After a couple of hours I can't keep my eyes open as the lid muscles are dysfunctional and squeezing my eye shut. Forcing through this phase causes more problem that only manifest the next day. Heavy pain in the muscles around the eye that takes days to fade. My pupils are huge as well and that seems to correlate well with my symptoms.

                      I need to go back to the plasma until my eyes heal up because I have been pushing through. Switching to Windows 7 did make a big difference though and for a while I thought I had actually found a fix that would last.

                      My rankings are now:

                      Panasonic ST60 (plasma, would be perfect except it has extremely high input lag. no good for multiplayer games at all) -> BenQ EW2440L -> BenQ EW2750ZL (too bright) -> Some Dell CCFL -> BenQ GW2760HS (way too bright) ------------> iPhone 6s (completely useless can trigger bad headaches quickly, I will not look at it for even a few seconds)

                        KM No, I didn't buy it yet... Sorry, I'm still using MacBook Pro Retina. By now the Macbook looks bearable (at the brightness of 6/16).

                          degen Honestly, I highly doubt it has anything to do with the monitor and a lot more to do with what is driving the monitor. Video card, video driver, OS display settings

                              Many people have been 100% cured by switching displays. PWM has been gone over to death here but we tend to forget that so many people switched to a PWM-free display, were fine, and never posted again here or in the Apple thread.

                              All of those things you mentioned are important for those of us who still have symptoms. After all this time all we basically still know is 'Intel graphics are bad, and use Windows 7, here are some techy theories why that's so'.

                              In that case changing display's is one of the only variables we can affect.

                                  degen If it helps, great, but I suspect changing a monitor simply alters the output of the offering device, which is the video display subsystem itself, and so doesn't actually fix the underlying problem. Who knows

                                    I purchased GW2760HS and EW2440L based on feedback from this forum. I love them! The EW2440L is more flexible in terms of adjusting the brightness and contrast levels.

                                    degen I guess I was wrong on this. I am using AMA on "Premium" setting for some days now and it is not causing more eye strain.

                                        KM I'm back to using the EW2440L after a break. It's still the best non-plasma display I have and the only display practical for doing office work or input lag sensitive gaming.

                                        The ghosting is insane without using AMA so I would probably use it myself anyway even if it did add a bit to the eyestrain.

                                        Wish I had something new to add but at least I am functioning, sort of. Now I'm just worrying about getting a back-up GPU.

                                            I am so confused at why the muscles around my eye get so tensed. The light doesn't seem offensive in any way and I don't have any pain. Eventually though I can barely keep my left eye (worse side) open as it feels like it is being squeezed very hard. Other muscles in my face and the side of my head will tense up as well, more so on the left side as well.

                                            Persists for a long time after too.
