ctsai89 Auto brightness is a nice feature, but probably nothing more. If you have a monitor that you set up manually the way you like but can't look at it, what would auto brightness change? I'm not saying you shouldn't buy and try that monitor, but you probably shouldn't do it just because of auto brightness.

Well with auto brightness: it's more likely I could avoid having to cover my window all the way up just because I want my monitors to be completely dim. Using the sunlight during the day sure is better for my eyes vs LED lightings in the room during the day. And I don't like my room completely dark, that hurts my eyes as well. I like it ambient.

I just today realized how reliant I am on the EW2440L for office use, which is not good as I've tried to find another as back-up and I can't. I had the brightness turned up to 5 as I was using the monitor briefly in another room with higher ambient brightness. When I brought it back to the office I noticed that images seemed sharper and edgier to the eye and I couldn't figure out what had changed. After a couple of days I have developed bad eyestrain where my eyes are half closed and the muscles around them are very tight. Remembered that the brightness was turned up a bit and urned it back to 0 tonight and hoping for relief. (Brightness of 5 on the EW2440L is still way dimmer than 0 on almost every other monitor).
I always keep phones/monitors at lowest possible. I also use an app called dark reader whenever I browse sites like this when I have to read long posts, I rather not see a white screen but my eyes do better when the screen turns dark.
But how dim should screen monitors really be? the best I've experimented with is lowest possible right before you almost can't see what you're trying to see on the screen. Anything higher than that will dry my eyes up.
Slacor seems like we need a pinned meta thread that summarizes our 'findings so far' i.e.
"these are phones/screens that multiple people have found usable" ,
"these are the physical problems we are having"
"these are our assumptions of the causes"
& also a little campaign of pestering actual engineers, psychs & eye docs to find the ones who might be interested in helping
My EW2440L has developed coil whine.

i´ve ordered a new EW2775ZH (270HVN02.3) because my second Benq GW2760S (AUOM270HVN02.0) died a month ago >To open Service Mode: Press Power on + Menu
unfortunalty it hasnt the same quality as my old one, getting eyestrain and fogginess after some minutes.
I am on win10 and i can see some flashing on the screen on static images like the windows desktop or the chrome browser. focusing is very difficult. this is very visible after opening a new window. it took me a while to focus the new content.
next i will order a newer benq model from 2018 (BenQ EW277HDR).
it has a newer panel revision AUOM270HVN02.6

good to know that i am not the only one.
what about the newer revision with "hdr" EW277HDR?
it uses a newer panel. have you tried this one too?

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.
Did you try adjusting down the RGB channels? The defaults in my HP have all the channels at 255. Taking those down will drastically lower the minimum brightness.

degen "I can't find the EW2740L (measured at 11 cd/m² at 0% brightness)"
Do you also take down the RGB channels from the default 255,255,255, and reduce the contrast level? That will allow you to get a much darker screen at 0 brightness, probably too dark even on units known for being too bright.
I just read this: "and I kept the OSD contrast at 10."
So you've done that already, but what about taking down the RGB channels? That will make a big difference.
